Message 75870 - Posted: 24 Apr 2014 | 16:23:40 UTC

Problem short description:
First pps_sr2sieve task(s) failing with message "Output file pps_sr2sieve_xyz for task pps_sr2sieve_xyz absent"

Scenario:
BOINC client version 7.2.42 for x86_64-apple-darwin
OS: Mac OS X 10.6.8 (Darwin 10.8.0)
CUDA: NVIDIA GPU 0: GeForce GT 330M (driver version 5.0.36, CUDA version 5.0, compute capability 1.2, 256MB, 178MB available, 158 GFLOPS peak)
OpenCL CPU: Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz

Detailed description:
Upon client update with subsequent work fetch for NDIDIA GPU six new tasks were uploaded.
After a few seconds in most of the cases the first task, in rare cases up to the first three tasks terminated with abortion errors like the following:

"...
24-Apr-2014 15:57:12 [PrimeGrid] Requesting new tasks for NVIDIA
24-Apr-2014 15:57:14 [PrimeGrid] Scheduler request completed: got 6 new tasks
24-Apr-2014 15:57:16 [PrimeGrid] Starting task pps_sr2sieve_73193435_0
24-Apr-2014 15:57:22 [PrimeGrid] Computation for task pps_sr2sieve_73193435_0 finished
24-Apr-2014 15:57:22 [PrimeGrid] Output file pps_sr2sieve_73193435_0_0 for task pps_sr2sieve_73193435_0 absent
24-Apr-2014 15:57:22 [PrimeGrid] Starting task pps_sr2sieve_73193373_1
..."


In most of the cases then the second task, in rare cases the fourth task started and terminated without errors.

Regards

Joerg

The tasks were working a few weeks ago, but aren't now. Since the app hasn't changed, we should look for changes in the configuration of your laptop, or in the way the laptop is being used.

Has anything changed recently?

Hi Michael,

I went through the stdoutdae.txt log file;
since Feb. 11th, 2014, the error has occured each time when the CUDA PPS sieve project had been activated and the work fetch was initiated (13 times in total).

The mysterious missing output file error was occuring each time only for the first task processed, and in a single case for the first three tasks.
The second task (or, in one case, the 4th task) and all later tasks ran smoothly afterwards, though.
The CUDA driver version is 5.0.36; which is the latest version available for this HW/OS combination.
Note that the graphics card has no DP capability - but should this have an impact?

Let me know what other information, log files, etc, are required to resolve this issue.

Thanks in advance and best regards

Joerg

Something changed on your computer. It was working before, now it's not. You need to figure out what changed.

Message 75883 - Posted: 24 Apr 2014 | 23:22:20 UTC - in response to Message 75877.

Addendum I:

the task abortion with the computation error is observed in a second scenario.

Steps to reproduce:

1. Within the Tasks Tab of the BOINC client, suspend pps_sr2sieve tasks while they are in status "ready for execution" (this is the case when another pps_sr2sieve task is in active state)

2. Wait for the active pps_sr2sieve task to finish and to upload the result.

3. Resume the suspended pps_sr2sieve tasks; the first will fail with the "Output file ... absent" error.

Addendum II:

the task abortion with the computation error is observed under BOINC client versions 7.2.33 as well as under 7.2.42

Referring to your remark on changes on the computer I have no clue what may impact the error; one suspect should be ruled out as the OS has not recieved updates recently (OS X 10.6.8 is more or less out of maintenance sadly).

Same goes for hardware modifications - none recently.

If you have other suspects, just let me know so that I can check.
Just in case you have access to the underlying code - looking from the application (coding) side: what can cause the application to throw the "Output file ... absent" error message - can that be a timing issue?
I have had a look into the respective slots subdirectory where the running pps_sr2sive task is currently assigned to, but there was no such output file.

Thanks in advance and best regards

Joerg

Unfortunately, that error message merely indicates that some problem occurred, and gives no help in figuring out what the cause is.

The best suggestion I have is to take the following steps:

1) Uninstall BOINC

2) Delete the entire BOINC data directory

3) Reinstall BOINC

If that doesn't fix the problem, you can also try the following:

4) Uninstall the video driver.

5) Reinstall the video driver.

OS X 10.6.x is really old and rumor is that Apple is not supporting it anymore.
I had 10.7.5 running on my mac pro and I could not get my GTX 470 to crunch anything until I upgraded to 10.9.x. Just something to ponder.

Of course a Mavericks upgrade might be an option.
As the laptop in question is no designated cruncher I have (many) good reasons to stay with 10.6.8.
Being an Apple customer since the early nineties, experience has taught me to switch to the latest OS version on non-test systems only after some maturity latency.
For Mavericks this shall be at least 10.9.4. for this system.
I have another box where a test system currently is crunching on a 10.9.2 partition, but the productive partitition on this box is on 10.8.5.

Hi Michael,

thank you for your feedback. I'll follow your hints considering the CUDA driver and BOINC client reinstalls after the currently running tasks have completed and will report on the outcoming.
