This is the information from the task page. I do not know what has caused this error but it seems like rosetta can't access/write the files it needs.
Have you tried resetting the project?

PS. It looks like WU are still failing on that machine, last computution error was reported today.

Normally just exiting BOINC and all science applications and then restarting them clears this error for me! No idea what causes it on my network.

Hey!!

Lately, I have started my computers crunching Rosetta@home again.
However, after reviewing the completed tasks, I find that my main quad core computer is constantly being granted less credit than it is claiming whilst my dual core one is the opposite!

Is there any reason for this?

Well, since you have your computers hidden, we can't look at the WU's that have failed and tell you why! Can you post a link to a few of the failed WU's please?
From my understanding, computation errors occues when there is an issue with a task on your computer and it either corrupts, fails to finish or there is some other error which makes BOINC exit the task. Validation errors occur when a tast has been uploaded and fails the automated validation checks.

Yes - agreed with above. If you are not running any GPU (CUDA) applications then I would downgrade to 6.4.7 if you are having problems. All of the 6.6.x clients seems to have major problems still.

Both your computers listed in your profile are showing new work units. I'm guessing this problem has fixed itself. In my experience this occurs when errored work units are reported.

Post:
The number of GPU requests will decrease over time. The new scheduler requests and deals with CPU and GPU tasks and requests seperately, therefore it requests them individually. Your BOINC manager therefore must have the correct amount of work for your CPU already.

There is not fix that I can see, other than suspending the CPDN project tasks and requesting new rosetta ones. This is a bug with the scheduler that has been pointed out to the developers many times.

I know that Primegrid where trying to create an ATI application however ran into problems and dropped the idea for now. Anyone else got clarification of all projects which have or are developing GPU apps??

On a side note: Folding@Home which is non BOINC based project supports both ATI and Nvidia GPUs.

I would also assume that the project time duration correction factor plays a part in this error. Also, please remember that on the requests which are asking for GPU work, they will always recieve 0 new tasks because rosetta has no GPU applications or tasks to send.

Post:
I'm guessing that the BOINC client does some calculations on CPU time which is available on your computer and reports the data to the rosetta server during the scheduler request for new work. It is then the rosetta server that decides the tasks will not be finished in time and gives the error.

Will 6.6.36 BOINC manager enable a CUDA enabled device to work on Rosetta @Home.
I hope so. Because the head of BOINC came out in a statement a while back (6 months ago) that to reach an exoflop would require GPU type devices. I dont think Rosseta will ever get enough computing power untill an exoflop is reached.


No Rosetta@home does not have a GPU application, nor is it going to have one in the near future. There is a huge thread on the topic on this forum, have a search for it. It will give you all the details for the discussion.

Has there been any talk of even bringing GPU work to Rosetta? I would think bringing the power of GPU folding would benefit this project greatly if done right.


So much talk that it is a dead horse that no one wants resurrected.
Is this Boinc client requesting GPU work a strain on the Rosetta servers? If so I will go back to version 6.4.5 and get rid of 6.6.63


I just checked through all my messages on one of my CUDA ready machines which isn't actually CUDA crunching anything currently. I see no GPU requests from this machine (using 6.6.36).

Hey,
I just came back to crunching seeing that CUDA is available to my graphics cards. Started all that stuff, but it seems I only get tasks for CPU.
Boinc sends requests for GPU work but never gets any tasks, whereas my CPU tasks flood the computer...
Didn't find anything on GPU issues, so what's that about? Why don't I get any work?


Because Rosetta does not do gpu processing right now. Only a few Boinc projects do...Seti and Milky Way come to mind right away. Milky Way is very iffy as to when and if you can get work, some have no trouble, some can't get any. If you want to crunch outside of Boinc, at Folding@Home you can use both Nvidia and ATI cards.


Seti@home is also having work problems at the moment because Astropulse which is a subproject is not working, causing huge strain on the other work units. I am able to get some but not enough to fill my cache. GPUGrid seems to be the most reliable project for giving GPU work, however, unless you have a reasonably fast nVidia card (64 cores or above) you will not meet the WU deadlines.

I find that HP's given temperature ranges for their computers are never actually correct. It is much better to find out what hardware components are in your PC and check each one with the manufacturer as they will give much more accurate figures.
My HP Pavilion a6430.uk with an AMD Phenom x4 9600 and an nvidia 8500GT is good up to a CPU temperature of 72ish degrees C and the graphics card is good up to just over 100.
When running BOINC 24/7 + CUDA, the CPU cores run at a constant 55 degrees C and the GPU at around 68 degrees C.

Mine are coming through very slowly and one by one. However, I still have about 36 hours cache time left provided I have no more errors.

They are failing with error 161. The validator is given the full claimed credit for these results so no harm done.


No it doesn't, or at least not in my case.

257062181 304453 7 Jun 2009 12:41:55 UTC 10 Jun 2009 22:27:57 UTC Over Client error Compute error 29,120.28 74.19 ---

But after those 2 failed WUs, so far I've returned 4 valid ones.


Yes it does.
Have a look at the actual work unit page for the first task you have outlined above: http://boinc.bakerlab.org/rosetta/result.php?resultid=257062181
At the bottom of the stderr out section it says:
<message>
<file_xfer_error>
<file_name>lb_thread_all_multi_hb_t326__IGNORE_THE_REST_12732_232_0_0</file_name>
<error_code>-161</error_code>
</file_xfer_error>

</message>

Which is the error message and below that it says:
Validate state Invalid
Claimed credit 74.1858587672511
Granted credit 74.1858587672511
application version 1.71

Therefore the credit for the workunit has been granted even though it does not show up on the tasks list because the result is labelled "invalid".

There seemed to be a server outage earlier, however, we are still in the dark as to what happened. The scheduler is running, so I am guessing that there are just no available work units as lots of computers will be requesting new tasks. I am yet to get any new ones too.

Looks like there is a bad batch of tasks out currently. All of my lb_thread_all_multi* tasks that I have got recently have failed with compututation errors (Error 161 if i remember correctly). All of the tasks claimed credit is being granted by the validator so I am not too worried.
