Let's give thanks to Akos Fekete, of whose hard work and love of programming, who has stoked the fire of progress in Einstein@home. I thought that whoever concurs with me on this could drop a line or two (one post per participant, please).
Thanx Akos

I've dropped several already so one more can't hurt:
Thanks again, Akos, for your fine efforts and hard work!
Akos, I've never imagined crunching times that we're seeing now.
Your programming skills are very impressive, too bad Windows
programmers aren't more like you!
Thanks and Well Done!

Absolutely stunning, stunning and stunning!!!
A brilliant effort.
May this thread break records! :-)

Thanks to your improvements...I can crunch Einstein@home at a much faster rate...It was easy for me install the optimization...And i'm so enthused about the results coming in that i have allocated more resources toward Einstein@home.

Thanks Akos, and congratulations on a remarkable professional achievement.
I can only agree with the others.
Thank you.

Thank You, Akos, for your excellent work.
You have celebrated the 1st of May with three new releases. You are a real Held der Arbeit (hero of labour).
Alright, where do I go to d/l this thing? I presume it won't negatively affect any of my other projects? Will it overheat a laptop? I run einstein on one machine that is win ME and another win XP. Thanks.

You can download the optimized apps here. Just check with something like cpu-z what instructions your computer supports.
Lets try to keep this a thread dedicated to Akos

Thank you Akos for your brilliant work - the speed improvements are breath-taking. And thanks a lot for speeding up all - even very old - x86 CPUs with your optimized clients.

I think it's a bit ridiculous that you want this thread to exist so people can thank him for creating his optimized work but discourage people from asking how they should actually go about using it. Especially since this thread is/may be the first place some readers have ever heard of it.

I am sorry if that was the tone that you got from my post. I think it is great that you are asking questions and want to optimize your computer. I was in no way trying to discourage you or any others from asking these questions, I even provided a link to where you can find the answers. I was simply trying to state that this thread is not necessarily the place to post you question, start a new one, or take a look around and see if someone has already asked/answered your question in another thread. Akos has done a lot for the E@H community, and I didn't want this thread to get too side-tracked (as they tend to, and I admit to being guilty of that at the moment) from users sharing their thanks.

To Akos...what a guy..to put your time and talent to making this number crunching so "much" more interesting. I have been updating with each successive application you have provided...
Your "talent" is appreciated!!
I too wish to express my appreciation to Akos. It's simply breathtaking what my old crusty machines are capable of now. I've set my systems to focus on crunching just this project now until it's finished, so your efforts have not only made these systems much more efficiently utilized, but had the side effect of stoking up greater interest on my part on this project. Here's hoping that the visibility you get in this virtual world will result in rewards in the real one.

There're two different factors at work behind the speedup. The quality of the algorithm, and how efficiently it's translated into machine instructions. The later is generally a function of the compiler in converting from a high level design into assembly language. This can be done by either taking a c/c++/fortran/etc program which is easily and quicly writable and compiling it, or writing the asm by hand. The traditional number for c vs asm development time is 10:1. As compilers get more sophisticated the ammount of knowledge of exactly how the processor works needed to gain better performance grows increasingly high. Also, the vast majority of code in an app is seldom executed and hand tweaking would show little or no benefit. This, combined with the 10:1 devtime is why modern apps are almost never written in asm anymore.
The first factor, quality of algorithm is as much a factor of time/effort invested as anything else. And here in lies the rub. LIGO is a hardware project, not a software one. And as every EE/ME/etc knows, the hardware is the hard part where all the time/effort/money needs to be spent. Software on the other hand is quick/easy/cheap to develop, and can be given a tiny slice of the budget.
If Akos is reading this, I'd be interested in knowing what the breakdown on the speedup is between better algorithms (I know his 1st version was lagely this), and better implementation of existing ones (his most recent SSE/x87 fpu interleaving is this). And also how much of the code he's actually rewritten in a meaningful manor. I could do a binary diff, but anywhere replacement code was a different length than the original it would result in changed offsets throughout the app that would generate lots of false positives.

Well done, good stuff, happy hackings,
And happy crunchin',

Well done sir !
Tremendous publicity for the project too !

Great job, Akos!!
1. Only thinking of the time necessary for new generation processors to double the CPU speed we can realize the INCREDIBLE value of your job.
2. More important than 1 ... you SHARED it with us. Nowadays, this is an example.
Thank you very much!!!!
Kind regards.

I'm getting ready for S5 by switching almost all of my crunching resources over to Einstein@home...Your optimizations make this project even more exciting...We're getting closer, faster to discoveries that may change the way we think of the universe.
____________
Great job, Akos!!Thanks!
2. More important than 1 ... you SHARED it with us. Nowadays, this is an example.You are right!
As far as i know, these improved routines will be used for S5 phase too.
So it is also a good exapmle for coopearation.
Great job Akos! Just switched back all my machines back to Eintein because of you!
____________
Great job Akos Fekete !
I just wanted to thank you for the optimizations to the client program. I think such good low level programmer, who know about inside assembly are very rare. I would not be surprised when some great banks or software companys would offer you a job somewere in the world.
Greetings

Let's give thanks to Akos Fekete ... who has stoked the fire of progress in Einstein@home.stoked it? he's poured a load of petrol on it more like!
some exelent work, all my older computers are now crunching einstein too (they took too long with the standard app) and i've also increased my resource share for einstein as well :)
bring on S5! :D
it seems we're speeding through the S4 data ;)
again, many thanks, it's great to see speeds of 8 GFLOPS in BoincView :)

Thanks to our USER OF THE DAY - AKOSF! And congrats!

I just got his app on one of my machines (finally) and it dropped the crunch time down from about 5 hours to 1 hour.
I posted in the crunchers forum (optimized apps) some questions for other machines so I can get them humming along like my first machine is.
Truly amazing.

Ok...one question. When they come out with this S5 data will we have to uninstall ur optimized apps or reinstall new ones? Etc....what do we do then?
---Thank you.

The way Akos' apps are, S5 will automatically download and start running, without any issues. S5 is already going to be generically optimized, have not heard if someone is going to do specific optimizations or not.
____________
OK, in light of recent happenings I'm going to revive this thread.
Thank you Akos, I hope your S5 efforts are eventually appreciated by the scientific community, and that they can be integrated into the stock client in the near future, I understand the reasons why we had to stop, as soon as an EinsteinBeta@home project starts I'm signing up.
I think I can say that every cruncher who's ever used your optimisiations both appreciates AND recognises your ability and enthusiasm for this project and it's sucess.
Keep going, and don't get downhearted.

To quote Albert Einstein,
“The most powerful force in the universe is compound interest�.
As soon as there is an " Einstein@Home.Beta " I'll return to donate
my " Wasted CPU Cycles " to this project.
Hopefully -"- akosf -"- will be there, " wasted cpu cycles " permitting.
I realize that with a tightening of the qourum to 2 results, some adjustments
needed to be made, but I wonder, how many " scientists " actually looked at the
output of the so called " Official App ", and nodded their approval. Maybe they
just looked over the source code and gave their approval, placing their faith
in Intel, Microsoft, or whatever for the binary to pass muster.
This I believe is the greatest error in the "BOINC Paradigm".
There's no such thing as a " wasted CPU cycle ",
I believe I can count on Intel/AMD to defend me on this.
There is a marginal cost to each cpu cycle above "sleep".
I don't think it's asking too much of "BOINC" to assure me that
every cycle I donate is used wisely, efficiently, and in good faith.
Your 2 cents are up.
guido.

Thank you, Akos. Let's hope the project fixes its database issues before it's too late to speed up crunching S5.
I have nothing to add to Guido's message except that.
