    Bruce,

    Can you give us the latest on the possibilities of getting the Albert application in optimized forms? WIth the Altivec version I see super performance and know that this is also (based on SETI@Home experience) potentially possible with the PC type CPUs. I know that to have decent coverage there would have to be about 7 different "flavors"

    1) Standard
    2) AMD SSE2
    3) AMD SSE3
    4) Intel SSE2
    5) Intel SSE3
    6) I forget
    7) I forget #2

    Is it this complexity and the difficulty of ensuring the download brings the correct version down?

    Or something else?

    Or, the check is in the mail?

    Enquiring minds want to know! :)

      I think I read somewhere that Albert was basically automatically optimized. When it detects that SSE3 or whatever is available it automatically runs code better suited for that instruction set.

        Hmmm,

        I don't think it is doing a very good job then. If it was, I would expect closer concurrence between the G5 and the Xeons and I am not seeing that at all ...

          Even if it is too difficult to have boinc d/l the appropriate app it could be left as is. Then have a seperate d/l page where we can d/l the one we need and manually install the app. A lot of us are quite familiar with this proceedure because we have done so with our seti apps.

            @Paul:

            Make that

            1) Standard
            2) AMD SSE2
            3) AMD SSE3
            4) Intel SSE
            5) Intel SSE2
            6) Intel SSE3
            7) I forget

              If you're at this, make it that:

              1) Standard
              2) MMX
              3) MMX + 3Dnow
              4) MMX + SSE
              5) MMX + 3Dnow2 + iSSE
              6) MMX + SSE + SSE2
              7) MMX + 3Dnow2 + SSE
              8) MMX + 3Dnow2 + SSE + SSE2
              9) MMX + SSE + SSE2 + SSE3
              10) MMX + SSE + SSE2 + SSE3 + iA64
              11) MMX + SSE + SSE2 + SSE3 + VT
              ...

              ... you see a complexity in this pattern? ;)

                During the last weeks and months we have been mainly busy with getting the Albert setup working, so I had not much time to spend on further optimization.

                - The AltiVec-version of code is hancoded, explicitely using vector instructions where possible (at least in the very core of the program).
                - On Linux, if SSE is detected the App switches to a part of the program that has been optimized for SSE by the compiler (gcc 3.4 or 4.0).
                - On Windows we use the stock MSC compiler (7.1) on the generic version of the code.

                I played with compiler options, compiler versions and modifications to the code for quite some time, but found the following measurements not to give any significant improvement in the calculation times compared to the Apps we currently deliver:

                - prefer SSE2 over SSE when available (Linux)
                - use hand-coded vector code (for SSE2) instad of leaving the optimization to the compiler (Linux)
                - use SSE(2) optimization of the MSC compiler (Windows)
                - use icc (the Intel compiler, version 8) instead of gcc or MSC

                So my preliminary conclusions are that
                - The MSC compiler does a suprisingly good job, at least on our code
                - The SSE optimization of gcc seems to give results that are (nearly) as good as hand-written code
                - The AltiVec Unit is simply better (and somewhat easier to program) than the SSE stuff; thats why I desperately regret the decision of Apple ragarding CPUs.

                I began to play with the auto-vectorization of gcc-4 and icc-9, but without a usable result yet. It's something I'm still working on.

                  Jobs did it to me with the Lisa, now I have a G5 he is at it again. Sorry, it is all my fault. I was thinking to go all PowerMac over windows.

                  I guess I will have to rethink that one. Though, I would like to get a Quad this year.

                    Hello Bernd,

                    thx for sharing that information! It's good to hear that devs are looking into this. When I compare this to the optimization process of the seti application, several things come to my mind:

                    - I think the largest single contribution in s@h was the caching of FFT results.. anything like that possible here?

                    - 2nd was the usage of a special FFT library, can't remember the name but it was hand coded for different CPUs and instruction sets
                    -> since e@h searches for periodic signals I suspect you're using FFT as the main algorithm as well?

                    - 3rd was the impact of using the icc 8 or 9, with different flags for p3, p4, p-m and with some tricks the p3 version worked for AXP as well and they made a A64 version
                    -> would it be useful to talk with the seti guys about their optimization experiences with the icc? (thinking of TMR, crunch3r, Harold Naparst)

                        Hi!

                        I did a hand-optimized version of the albert code. (windows, no SSE)
                        It produces absolutely correct results, but at least two times faster.
                        Can I use it without any kickback?

                          I do not work here or anything, but speaking in general, I think it would be best to submit your changes to the E@H staff, so 1. they can validate your claims, and 2. they can possibly use those changes in their main albert client

                          Having a 2x improvement in windows would be a huge help if the results are really just as accurate.

                            I second that one: a 2x speed-up would be huge. May I ask how you got the source code?

                              Who's to say he did. Hand optimizing asm isn't much less difficult than running a disassembler on an executable to get (undocumented) asm out. Farthermore, running the app under a debugger would allow you to profile the execution and determine where the code was spending most of it's time, and thus where to concentrate the optimzation.

                                    Any results on this so far? Any beta-testers needed? :)

                                      I would like to help on speed optimization, but i don't know what is the way of it. Probably i can put my code on a webpage, but i think it would be not legal. I didn't get any e-mails in connection with legitimacy.

                                          Are you currently using your modified binaries? Because wow, 345.38 RAC is pretty good for an athlon 1700

                                            I seems so. He's crunching 1.5 times faster than my 2.5GHz X2 (for one WU)! That's damn impressive, even if the 1700+ may be OC'ed :)

                                              This is my fault -- I got caught up in some urgent things at this end. I've just written to you off-list.

                                                  Yes. Akosf has done three things to speed up our executable. One of these optimizations is very clever: it eliminates large numbers of (slow) divisions. We're in the process of building and testing new executables (for all platforms) that incorporate these changes. They should result in very substantial speed-ups.

                                                          Yes. Akosf has done three things to speed up our executable. One of these optimizations is very clever: it eliminates large numbers of (slow) divisions. We're in the process of building and testing new executables (for all platforms) that incorporate these changes. They should result in very substantial speed-ups.

                                                          If you need someone to help test in Linux, just give a shout!

                                                          I am really looking forward to this.



                                                          I'm also running Einstein exclusively in Linux and would love to help.

                                                              For Seti, I saw that the best boost is done with SSE2 optimization, and a lot of people own an SSE2 enabled CPU.
                                                              It shouldn't be too time-expensive to build only one optimized version...

                                                                          How many different GPUs are in the wild? Who will test the application?

                                                                          I think this is the biggest problem.

                                                                          I heard from someone over at SIMAP that there are two major flavors of GPUs. ATI and Nvidia. There are also some integrated intel gpus.

                                                                          Apparently they have already been using gpus in Folding@home. One guy has a link to a gpu compiler, looks like it will definetly work for newer gpus of both flavors, and it might work for older ones.

                                                                          At the bottom of his post he said
                                                                          "Above readings may enable u to mount u 2 teraflops desktop at low cost
                                                                          that is: about $20K

                                                                          ps: 1 teraflop == 1000 gigaflops
                                                                          Happy crunching :D"

                                                                          Here is the link to the SIMAP page about it. The gpu posts are at the bottom of the page.

According to the articles that I read at the time, their schedule called for releasing those API specs in late-1st qtr - early-2nd qtr of 2006, so any time soon...

                                                                            This family of GPUs covers a broad cost range, from moderate to very expensive, and has now been out for about 4 months, so there are probably several already installed in some of our crunching rigs. I'm quite sure that those of you who have them would be happy to test.

I know ATI wants to push this, however, I don't know how this will look specifically. It would be great if they'd provide highly optimized math libraries.

                                                                                          I hope E@H team will release soon this new applications for all platforms, the "200 days to completion" will be hugely reduced.

                                                                                          But it will be necessary to increase again the maximum number of WU's per day a host can download. Faster machines will process now much more WU's per day.

                                                                                          Or, in the future, I suppose the WU's size should be increased, to avoid overloading the data server.

                                                                                                @ Bruce - Just a suggestion - when you multiplied the quota, it might have been a good idea to also multiply the penalty for errored results. When working with a quota of 32, putting a 1 WU penalty on a serial-error host is going to take forever to limit the damage. When the daily "q" was 8, a penalty of 1 was significant, a fast-working deterent.

                                                                                                Respects,

                                                                                                      I am thinking I will have to switch my Linux clients back to using wine again..



                                                                                                      I have put two of my linux machines back into wine mode running the new windows binary from Akosf, so far it appears they are also enjoying the same speed increase. I will know for sure once they are done computing.

                                                                                                                      So, is it good for us to use?

                                                                                                                              Moral of story:

                                                                                                                              1.) Make sure you exercise some caution before you slipstream it to all your hosts. Related to this, since this opti is essentially an RE hack, that might explain why Dr. Allen wanted to run it through the testing loop before releasing it as an "official" EAH app, because of problems like that.

                                                                                                                              2.) To announce to the EAH community with a potential CAYS link, with no explanation or even a link to a site to allow anyone to see what's up about it is irresponsible, regardless of how clever the work is.

                                                                                                                              3.) My gut feeling is Dr. Allen is not going to be too thrilled about this development.

I know it is validating and things, but getting a better official word makes me feel better.

                                                                                                                                        The drop in cpu temp's probably related to the fact that the biggest algorithm change removed most of the slow division ops, so you're not using that part of your FPU much.

Probably i can put my code on a webpage, but i think it would be not legal. I didn't get any e-mails in connection with legitimacy.

We know from earlier in this thread that he has shown his optimized client to Bruce. His post only contained the link to the application. No installation instructions, so you need some familiarity with BOINC file structure to be wiling to install it. Look at the timestamp of his post.

We know from earlier in this thread that he has shown his optimized client to Bruce. His post only contained the link to the application. No installation instructions, so you need some familiarity with BOINC file structure to be wiling to install it. Look at the timestamp of his post.

The fact remains that if EAH wanted to have app version variety in the wild they would have made the source code freely available and encouraged folks to have at it, like SAH does.

                                                                                                                                              I took Dr. Allen's prompt and positive responses as an indicator he found the proof-of-concept app had merit, but we would have to wait until as many of the ramifications of full scale release could be evaluated and addressed.

One and two halfs have validated successfully, the 4th WU is waiting on someone else, and won't be validated for annother day or two.

                                                                                                                                                  I hope E@H team will release soon this new applications for all platforms, the "200 days to completion" will be hugely reduced.

                                                                                                                                                  But it will be necessary to increase again the maximum number of WU's per day a host can download. Faster machines will process now much more WU's per day.

                                                                                                                                                  Or, in the future, I suppose the WU's size should be increased, to avoid overloading the data server.


                                                                                                                                                  I wound up getting a bunch of small WUs right after I installed this on my XP 1600 system and slammed into the max quota per day within 12 hours. :-P

I will know for sure once they are done computing.


                                                                                                                                                    There is definitely the same speed increase using the windows binary under wine(as to be expected). So for those brave few, time to bust out wine again to make Linux match up to the new and improved windows binary.

At 80-100m per big WU unless I get a swarm of little ones at once I should be ok.

The optimized app's benefitting small WUs alot more than big ones. My time on big WU's has gone from 210-240m to 80-100m or a ~2.5x speedup. I had a handfull of small WUs as well. They went from ~60m to 11-12m a 5x gain.

At 80-100m per big WU unless I get a swarm of little ones at once I should be ok.


                                                                                                                                                                          Now THIS is REALLY disappointing. At 8 min. after midnight (UTC) my XP 1600 system downloaded two .DAT files and immediately parsed them out to 32 WUs. It then flagged that system as at Max Quota for the day...this was at 12 min. past midnight (UTC).

                                                                                                                                                                          According to BoincView, all 32 WUs are short ones that my system will burn thru in about 21 min. each. That gives me just under 12 hrs of crunching on that system before they're all gone. Looks like I'm getting the swarm of little ones you were worried about. Well, Seti will get more crunching when I'm out of Einstein WUs.

                                                                                                                                                                          I downloaded the optimized app so I could do MORE work for Einstein and chop down that 200 days number a bit. I guess if I do work more efficiently for Einstein, I can contribute more to DC as a whole once I hit my E@H quota.

                                                                                                                                                                                        So, is the Ixx version better for Pentium IV?

                                                                                                                                                                                        I'm testing your A36 in a Pentim IV Northwood 2.4Ghz with good results, but if there is a better specific version, could you link this one here, as the two previous ones?.

I've tried the A36 on four different machines and I'm not seeing any difference in performance at all. As far as I can tell, I've got it installed properly - I'm just not seeing any difference in speeds.

                                                                                                                                                                                                *Edit: Okay.. perhaps I was going by the wrong thing.. benchmarks don't seem to change any, but after watching the client for a while it seemed to be going a little faster than the expected time for similar workunits. I guess I'll just leave it on a machine for a while and check back after work when I get home.

Using standard app time was 4hrs 20min on my xp2500+ @ 2.1 Ghz. Now using for two days your A36 and times dropped to 1hr 45min. THat makes it almost 2.5 times faster, amazing! And the short wu only take 30min.

Using standard app time was 4hrs 20min on my xp2500+ @ 2.1 Ghz. Now using for two days your A36 and times dropped to 1hr 45min. THat makes it almost 2.5 times faster, amazing! And the short wu only take 30min.

I went from ~60m eta on some using the old app, to 11-12m using A36, on my 2.4gig A64x2.

Curious as to why your 'short' WUs are taking so 'long'. My XP 1600 is cranking them out at 21-25 min. each.

Can anyone tell me with which of the above an AMD "Athlon XP 2000+" and an Intel "x86 Family 15 Model 2 Stepping 9" would be considered compatible—or point me to a good reference?

Possibly the very lower power/performance cpu that from Cyrex currently owned by Via(??) might be equally neutered.

It is a p4(ht) 630, 3.0G prescott, sse3 (em64t). I've been using the A36, that is correct i hope? Thank you very much akosf for the optimization, it has helped this computer out immensely. :)

My machines about the same speed as his, and I've got a clutch with 25-30m etas about 2.5days down the queue.

Then the others done with A36 finished in 32 min. That is still the same rate of increase I saw with the longer wu's.

It seems that the A36 best for the Pentium M 745, is that correct?

If you need access to a Linux machine, I can give it to you.

Going from 75k+ seconds to around 28k seconds is a huge drop in compute time. Puts new life back in these old cpu's and will save me both time and money. I can do more work, in less time, on the same hardware, for the same cost!

Now it's time to install A36 on the last 4 'puters.

Seems to be running fine on a K6-2, and hopefully I'll be back in around 100 Ksecs. or so with a positive report! :-)

I've got one system that runs out of WUs (the small ones) in less than 12 hrs. (That's all it's been getting since I switched to the optimized app.)


                                                                                                                                                                                                                                                                I just got a batch that's running around 14 minutes each. At that rate, I'll be out in less than 8 hours. I don't run anything but einstein now, so if they don't increase the quota, my cpus will get some well deserved rest.

Nobody can do everything (and do a good job of it, that is).

Shouldn't forget the Solaris, either.

Judging from comments Bruce's made earlier the gains from hand optimization vs letting the compiler do all the work are very minimal outside of altivec macs. Which means that first he'll have to convert aksof's enhancements (improvment's in the fundamental algorithm) back into C(++?) and build executables for all the various platforms before releasing anything.

Related just to credit, the new boostapp will do nothing. The only one who's getting use out of it is the project itself and science intended crunchers (like me) ;-). AFAIK simply because your credit is just referred to your crunching speed (FLOPS/IOPS) and time (crunching 10k seconds on 2 wus instead of 1 does't change the total time spent for the project, it just cuts the credit in half per wu).

It saves time because it does more WU's in the same amount of time and I don't have to think about upgrading the systems. That's pretty simple isn't it?

It saves time because it does more WU's in the same amount of time and I don't have to think about upgrading the systems. That's pretty simple isn't it?

If you're counting wus(useless for yourself(!), just useful for the project itself) then ok. Nothing related to BOINC recuires an upgrade so you are not forced to do so. If the app gets faster and all use it your system is relatively as slow as before so if you want to speed up relative to the others the need of new hardware is clear independent of the software ...

Related just to credit, the new boostapp will do nothing. The only one who's getting use out of it is the project itself and science intended crunchers (like me) ;-). AFAIK simply because your credit is just referred to your crunching speed (FLOPS/IOPS) and time (crunching 10k seconds on 2 wus instead of 1 does't change the total time spent for the project, it just cuts the credit in half per wu).

If you're counting wus(useless for yourself(!), just useful for the project itself) then ok. Nothing related to BOINC recuires an upgrade so you are not forced to do so. If the app gets faster and all use it your system is relatively as slow as before so if you want to speed up relative to the others the need of new hardware is clear independent of the software ...

                                                                                                                                                                                                                                                                                                      btw: this is no attack on your person, k? I just wanted to illustrate the situation for credit hunters ... chill out :)


                                                                                                                                                                                                                                                                                                      OK, I'll make this simple for you: I have 2 P4's, one is a 2.8e and the other is a socket 423 @ 1.5Ghz, everything else is either dual or quad PIII Xeons at 500-700Mhz. Since the changes to the app allow each cpu to do more work in a give length of time, that makes the cost per WU go down. We are talking cost of the power to keep the farm running. Overall cost stays the same but the cost per WU is reduced.

                                                                                                                                                                                                                                                                                                      Run time for the old Xeons was in the range of 75k-95k per WU, depending on the speed of the cpu in question. Time per WU has dropped to 25-30k. The only other way to increase output would be to replace the systems I already have since they are all running the fastest cpu's they will support. Or, I could add another 6-7 machines of the same speed. Hence, it saves me money because I don't need to replace the systems, or add new ones to increase the amount of work done. And, it saves me time because I don't have to spend the time, and money, looking for the parts I need nor do I have to spend the time to build new systems. It saves me time and money, with the added benefit to the project of getting more WU's done in a given length of time with the resources they have available to them.

This is not the point we are talking about. You write that the money/wu is reduced. Absolutely correct but wus are crucial for the project not for your person.

There is no "need" from the project side.

Maybe you force yourself? This is independent of the software. I can force myself too to build another system, yes, now, tomorrow, yesterday ...

If you now stop crunching anything, then you have saved money and time because you are finished earlier, ok. But I guess you will search for another task for your cpus (S5 or something completely different) and if they are finished you are again searching and so on ... so your cpus are used all the time, indepently to what project they contribute. So money and time is the same.

                                                                                                                                                                                                                                                                                                        So we see, we all could but nobody has to upgrade. Just if you want to enlarge your contribution to the project there is a need to buy new hardware if the app doesn't change. Maybe you are so noble-minded and still want to increase working speed then it's a break for you and you would save money and time for a certain moment ... :-)

Your application is gret, my crunching times are half. Would you be able to send me, or post a link to linux binary code for albert application? Or your binary for windows ? Maybe we would be able to make something with Linux and OSX version. Thanx, gabberattack

Do we know what the 'official' view of these new apps is at the moment? (sorry if this is posted elsewhere but I couldn't find it)

Mainly I suspect the delay is in translating the assembly back into C to allow crossplatform development.

                                                                                                                                                                                                                                                                                                                                Bruce's promised new, official applications based on akosf's algorithm improvements, but they haven't done so yet. Mainly I suspect the delay is in translating the assembly back into C to allow crossplatform development.

But we haven't started distributing this faster application yet, for a simple reason. We are worried that our project server might break with the increased upload/validation disk load since the work will be getting done faster when we begin distributing new apps to all users. So we're upgrading the disk controllers and should be ready for this increased load soon.

                                                                                                                                                                                                                                                                                                                                  I can certainly understand why! The S38 optimized Windows SSE application does a workunit in about 0.30 the time of the current science application. That is like getting all at once over 3 times as many crunchers! At least that is a happy problem for you! :)

Would be interesting which app is faster, akosf's S-38 or the officially optimized one. Maybe the new official app will get another speed-up since Akos's further development may be not implemented yet.

                                                                                                                                                                                                                                                                                                                                      We've now incorporated Akosf's improvements into our source code. But we haven't started distributing this faster application yet, for a simple reason. We are worried that our project server might break with the increased upload/validation disk load since the work will be getting done faster when we begin distributing new apps to all users. So we're upgrading the disk controllers and should be ready for this increased load soon.



                                                                                                                                                                                                                                                                                                                                      Maybe you could just release the new linux binaries immediately. That way people like me aren't having to run wine to take advantage of the improvements in the new binary, and also, Linux is a relatively small share of the E@H computer base, so I doubt the increased WU's from the Linux machines would break anything.

                                                                                                                                                                                                                                                                                                                                      This would also allow for testing out the code before a widespread release.

It would only make sense if _all_ workunits have (e.g.) a longer integral time. But ok. They might merge several workunits to a single one.

That's so tiny market share that it will absolutely not overload your servers, Bruce :)

                                                                                                                                                                                                                                                                                                                                              We've now incorporated Akosf's improvements into our source code. But we haven't started distributing this faster application yet, for a simple reason. We are worried that our project server might break with the increased upload/validation disk load since the work will be getting done faster when we begin distributing new apps to all users. So we're upgrading the disk controllers and should be ready for this increased load soon.


                                                                                                                                                                                                                                                                                                                                              with all due respect, this problem is easy to solve. Rather than having 25+% CPU time waisted while running a known-to-underperform binary, I suggest to ask everybody to pay credit to other Hungarian's work (as I understood that Akosf is from Hungary) and thus run SZTAKI (http://szdg.lpds.sztaki.hu/szdg/) for a while. E@H updates its server in the meantime and we all will be back once you give the thumbs-up signal for it.

Would be interesting which app is faster, akosf's S-38 or the officially optimized one. Maybe the new official app will get another speed-up since Akos's further development may be not implemented yet.

We know akosf's gained very large improvements by changing the actual algorithm used. I'd be very interested in seeing if he's outdone the compiler in producing asm code as well. Excepting cases where the compiler doesn't know about new instruction sets (and special purpose processors without a good compiler) it's supposed to be very hard to do now.

The code can only be as good as you allow it to be. Alot of times people use variables in a way that makes them dependent on earlier calculations, and decreases the utilization of the CPU being able to do things in the pipeline.

I've gone from around 5 hours to 1 hr 15 min.

                                                                                                                                                                                                                                                                                                                                                              We've now incorporated Akosf's improvements into our source code. But we haven't started distributing this faster application yet, for a simple reason. We are worried that our project server might break with the increased upload/validation disk load since the work will be getting done faster when we begin distributing new apps to all users. So we're upgrading the disk controllers and should be ready for this increased load soon.

Would be nice, though. If I ever get the OK to use the electricity to bring my old rig online, I'll probably use my backup XP_Mobile Barton in it, but if and when I get a place of my own, with no power restrictions, I have on or two old XP 2500 T'breds that may again see the light of electron flow. :-) For my Barton core (with SSE), the 3DNow! app is only about 1-2% faster than the SSE app.

If the only changes to the next official app are the optimizations, then there should be no reason why us AMD folks can't continue using the D40 app...probably with an app_info.xml file of course.

If the only changes to the next official app are the optimizations, then there should be no reason why us AMD folks can't continue using the D40 app...probably with an app_info.xml file of course.

As you've probably noticed, the last few have been relatively tiny "tweaks", amounting to 1-5%, compared to the mighty leaps (20-30%) of the first 3 or 4 Akos Miracles. If the next official app(s) do come out this way, I wouldn't expect that there will be much more optimization possible on top of what he's already accomplished. We're getting pretty demanding, aren't we? Geez, give the guy a break :-) They're already going to go through hell, just trying to get Linux and Mac into the same neighborhood, or at least get them into the same TimeZone.

Geez, give the guy a break :-) They're already going to go through hell, just trying to get Linux and Mac into the same neighborhood, or at least get them into the same TimeZone.

                                                                                                                                                                                                                                                                                                                                                                                      Bruce's promised new, official applications based on akosf's algorithm improvements, but they haven't done so yet. Mainly I suspect the delay is in translating the assembly back into C to allow crossplatform development.

But we haven't started distributing this faster application yet, for a simple reason. We are worried that our project server might break with the increased upload/validation disk load since the work will be getting done faster when we begin distributing new apps to all users. So we're upgrading the disk controllers and should be ready for this increased load soon.

This removes the strain on the project server's disk controller at least a little.

                                                                                                                                                                                                                                                                                                                                                                                      From a discussion in our team board, voices suggested handing over the source code to akosf since he has done so much great work. This would enable him to have his optimizations running on all platforms, to my understanding. Would that be at all feasible?

The triple co-incidence time (H1+H2+L1) is already at about 1200hrs - twice the length of the 600hrs we are analysing now for the S4 run. Someone here recently asked 'what next' - well it's coming! Also akosf's ( or any other ) optimisations are going to flow for S5 too and be very bloody useful!

                                                                                                                                                                                                                                                                                                                                                                                              These are distance estimates ( in Megaparsecs or Mpc ) to detection limit on current sensitivity for a 'standard' binary inspiral event - discovery of which is keenly sought. Because volume goes as cube of distance, a 20% increase in radius, say, gives about a 70% increase in the sphere of space enclosed ( 30% gives about another 120%, 40% gives about another 170% ).
                                                                                                                                                                                                                                                                                                                                                                                              The upshot is that S5, as we speak, has collected significantly longer times on considerably larger volumes of space. So who wants their computer(s) to host the calculations that reveal some real breakthrough for science?!

I was wondering how much "good" triple-coincidence time data they were collecting, because the intruments are so incredibly sensitive they pick up the very least bit of earthly background noise. In fact, imho, the sensitivity is such and the planet is so noisey that a space-based instrument seems probably best (and I know one is planned eventually).

I was wondering how much "good" triple-coincidence time data they were collecting, because the intruments are so incredibly sensitive they pick up the very least bit of earthly background noise. In fact, imho, the sensitivity is such and the planet is so noisey that a space-based instrument seems probably best (and I know one is planned eventually).

                                                                                                                                                                                                                                                                                                                                                                                                  Updates like yours are encouraging, and certainly keep up my interest in the project! :)

One then takes the signals used in that system to perhaps deduce the flexing/distortion of spacetime induced by a passing gravitational wave propagating through the entire LIGO. The poorer alternative is to not do that control effort, but measure the light fluctuation at that port..... )
                                                                                                                                                                                                                                                                                                                                                                                                  Anyhows, what makes the project not entirely hopeless here on Earth - given that we are looking for alterations in spacetime of the order of 10 to the power of minus 21 while using instruments, wavelengths, noises etc all far larger than that - is that most 'background' is incoherent. This means that many non-astronomical influences like the 'shot noise' of a laser, or thermal movements of the atoms in the mirrors do not have a preference with respect to the direction of the effect of scientific interest. A good analogy is the seaside where there is a lot of slosh, froth, wind, waves and spray etc.... but if you watch for long enough ( much, much longer than these 'obvious' disturbances ) the tide comes and goes. In other words averaging smears away such temporary upsets and allows trends to be observed. Another helpful method is to 'park' the noise in less critical parts of the observed data. So if you have some noise component that blurs a region of particular interest ( technically in the power vs. frequency spectrum ) then one can cleverly design widgets to interact physically with the detector parts to channel energy away into other 'modes'. So you ask the tenor to sing just as hard but in the baritone range! In addition, if you can't do that, then make the noise well defined, 'narrow', well studied, and understood - hence you can confidently subtract it away from the data. Another expectation is that widely separated detectors ought not suffer identical patterns of incidental noise - like a tree being felled in the Louisiana woods, or a brushfire in Washington State - so comparison between sites ( with simultaneously locked interferometers ) is quite valuable. Another trick is to get the chalk and pencil out and make a well educated guess as to what sort of signal ought to be heard for some given astronomical phenomenon, and then search for that in all the hubbub.
