Mine is the 9.18.10.3257 for HD4000

Which GPU? I tried a few old copies of the intel driver for my HD4600 after it didn't work in 8.1, to no avail.


Seems there is no driver on intels site for HD4600. For my HD 4000 there was one.

For me, the apps were "running" according to BOINC, but GPU-z showed no utilisation. BOINC % didn't move, then a while later i'd get a computation error.


Yes, that's exactly the behaviour. After changing to boinc 7.2.26 the computation error occured immediately

I've updated my notebook to Windows 8.1 and then ran the standard Windows update. One of this windows updates installs a new version of the intel graphics driver. After installation of this windows version driver, the GPU Apps didn't work anymore, with different errors depending on the Boinc version (no work progress with boinc 7.0.64, or calculation error with boinc 7.2.26).

The solution was to download the latest driver from the intel homepage (9.18.10.3257) and install it. But during installation the message occurs, that there is already a newer driver installed (the one, which came from windows update). So you have to confirm, that you want to install the "older" one.

After the installation the GPU apps run successfully.

empty space has a constant amount of energy content, a small but fixed amount for each element of volume. The Dark Energy*. But do take care to note that this really doesn't equate to an everyday concept very well, meaning that's it's not like we have a sample of it to play with. This recycles a concept brought up by Einstein himself, the so-called 'cosmological constant'. Back then Albert was trying to achieve something rather different though. He wanted to make a universe which wouldn't change much in size, a static flavour.


So if you interpret Dark Energy as manifestation of the cosmological constant, then there is another interesting aspect. Is the cosmological constant realy constant?

If you take the results of the WMAP mission, then the ingredients of the universe were changing over time. At the time, where the microwave background emerged (when the universe was 380000 years old - "scource wikipedia/wiki/dunkle_enrgie"), this were 10% neutrinos, 15% photones, 12% atoms and 63% dark matter. No dark energy, and, by definition, a cosmological constant with value 0. Today the ingredients are 4,9% atoms (baryionic matter), 26,8% dark matter and 68,3% dark energy. That means, that the dark energy increast over the the last 13,3 billion years. And therefore the cosmological constant should have changed with the increasing dark energy.

Looks like we are back in business here.

Just sent all my finished tasks in from all 7 hosts.



My uploads also were successful now

There seems to be still a problem....

No, there's no problem. Please note that every single line in the message text you posted is labeled [INFO ] and not [ERROR].

The messages change because each 'task' is actually a 'task bundle' and you are seeing the changeover between each sub-task in the bundle. In particular, look for the lines

[20:40:53][9684][INFO ] Data processing finished successfully! [20:40:53][9684][INFO ] Starting data processing...


that indicate that one sub-task finished correctly and a new one was started. Of course, as a result you will then see

[20:40:54][9684][INFO ] Checkpoint file unavailable: status.cpt (No such file or directory). ------> Starting from scratch...


simply because it is a new sub-task.


I understand.I saw the messages in the context with:

"Statistics: count dirty SumSpec pages 505426 (not checkpointed), Page Size 1024, fundamental_idx_hi-window_2: 1100505"

I don't know, if that means anything.

And here's the result:
The testtask was processed successfully, uploaded and is waiting for validation
Here is the link.

There seems to be still a problem. Look at timestamp 20:40:40 and 22:09:59 in the attached Stderr.txt

STerr.txt shows the follwing messages

Thanks, yes, it should be :-)


Access to Alber@home is OK now.
I set up the same configuration, with wich I detected the defect.
At the moment, everything seems to be correct. status.cpt file was created correct an checkpoints are written. That's already far beyond the point, where the error occured.

I let the task process completely until the end and will then give a final statement. But at the moment every thing looks good.

Sorry, we're also testing full SSL site access on albert. I disabled it again so you should be able to contact the server flawlessly now.

Thanks for testing this as well ;-)

Oliver


I will do the retest tomorrow, when I'm back in the office. Hope SSL is still disabled then.

We deployed BRP5 v1.38 on albert (test project) which contains another set of upstream patches that should (hopefully) finally fix the issue. In order to limit our deployment effort we just released the Win32-CUDA and Win64-OpenCL versions.

@Rechenkuenstler/Claggy: please test and report back.


Thanks,
Oliver


Sorry. I have been away for a few days. Sure, I will retest and report.

Cheers

Posted 4 Jul 2013 by Profile Rechenkuenstler
Noticed the following in the BOINC Event Log.

03/07/2013 03:03:53 | Einstein@Home | Task PA0057_01191_213_5 exited with zero status but no 'finished' file
03/07/2013 03:03:53 | Einstein@Home | If this happens repeatedly you may need to reset the project.


This is repeated several times for this task which has not finished yet.

What does this actually mean. Is it important. Do I need to reset E@H.

If this is important, the message is well hidden with no highlighted indication there is anything wrong.

BobM


Look here http://einstein.phys.uwm.edu/forum_thread.php?id=10193

Check if you have a status.cpt file in the slot subfolder. I suppose you don't.
Depending in your settings, the task will not restart, until calculation is done. Then it can,t create the finished file.

For now, the version 1.36 was deprecated. However, to solve the problem, those who experienced this problem can attach to Albert@Home at http://albert.phys.uwm and try to reproduce the problem with the debugging settings I mentioned above.

Sorry for the inconveniences
HBE


I think, it's not that easy. And they wouldn't have deprecated Version 1.36, if there weren't a problem. I think, the developers will find it and fix it. Everything else is speculation

Hi Oliver,

here is the test history. You can't see the stderr.txt files on the webpage, because I aborted the tasks, when the result was clear.

success with 7.0.42 reproduced
error with 7.0.64 reproduced
7.0.55 error
7.0.47 error (plus 2 x freeze of the graphic card when restarting from scratch)
7.0.45 error
7.0.43 success
7.0.44 success
7.0.45 error reproduced
7.0.44 success reproduced

7.0.45 is the first bad one.

Regards

I've switched back both computers from Boinc 7.0.64 to Boinc 7.0.42 and on both computers BRP5 is running successfully


This is interesting indeed. It would be really helpful if you could help us identifying the exact client version that introduced the error. If you're willing to do so, these are steps to follow:

1) Attach to our test project at http://albert.phys.uwm.edu/
2) Reproduce the error with 7.0.64
3) Reproduce no error with 7.0.42
4) Iteratively bisect the versions between those two, available here: http://boinc.berkeley.edu/dl/

By 4) I mean: given the following available versions...

* 7.0.42
* 7.0.43
* 7.0.44
* 7.0.45
* 7.0.46
* 7.0.47
* 7.0.48
* 7.0.52
* 7.0.54
* 7.0.55
* 7.0.56
* 7.0.57
* 7.0.58
* 7.0.59
* 7.0.60
* 7.0.61
* 7.0.62
* 7.0.63
* 7.0.64

4.1) pick the last working version (start with 7.0.42) and the first non-working version (start with 7.0.64)
4.2) pick the version in the middle of the set (start with 7.0.55) and test if it's working
4.3) if it's working it becomes your new "last working version". If it's failing it becomes your new "first non-working version"
4.4) continue with 4.2 until you found the failing version that introduced the error.

Please note: each test you run will reduce the versions remaining to be tested by 50%, hence will quickly tell us which client version introduced the problem (assuming that the bug was introduced in one of the version between the two you reported).


Thanks in advance,
Oliver


Hi Oliver,

tried to perform the testing. The problem is, that there are no Tasks available for BRP5. Tasks to send = 0. And I get the message from the boinc client, that there is no work available. So we have to suspend the test until tomorrow evening. Please make sure, that there are tasks available on Albert@home.

regards
