Message 123398 - Posted: 12 Dec 2018 | 6:55:02 UTC

Just swapped a GTX 970 from one PC to another, tried to run GFN and I get an error after 2 seconds:

Output file genefer16_20259418_0_r1191446169_0 for task genefer16_20259418_0 absent

Both PC's were doing GFN before the swap with no problems.

Any suggestions?

Thanks

That same issue happened to me recently, completely out of the blue. I reinstalled graphics drivers from nvidia and it went away...

No suggestions, but to comment I have seen this on CPU tasks as well

The output file is absent because the task fails before it begins to produce any output, and it is the boinc client that produces that message when it cannot find the file to send back.

So it could be almost any error that is almost immediately fatal at the point where control is passed to the PG code.

In the case of graphics cards my initial guess would be drivers?

More detail:

On CPU tasks I have seen it twice. Once it was triggered by having grossly insufficient memory allocated to the virtual machine running BOINC, and the other time it was an as-yet unidentified effect that only occurs when the Xen hypervisor runs a virtual machine using the Qubes OS and then only on PPS sieve. There were too many interacting bits to properly identify the actual trigger.

For your sake I hope it is drivers, as it is reasonably straightforward to check which ones were involved with each card before and after the swap

Don't waste time (as I did) looking for the output file.

Do look at the stderr listing on the website for your task -- there is a slim chance it might tell you something helpful.

Looks like Windows did an update just before the errors started.

Re-installed graphics drivers and all is good now.

I am getting this error consistently every time one particular machine does GFN16. It is by far my slowest machine so I assume it is a race condition. I have removed GFN from its permitted calculation types but it has got one more queued up.

It's not a race condition, but it's possible the app needs a cpu feature that your Athlon(tm) XP 1800+ lacks.

For others who might be looking into this, it's a 32-bit linux CPU task , and the error shown in stderr is :

<core_client_version>7.6.33</core_client_version> <![CDATA[ <message> process got signal 4 </message> <stderr_txt> </stderr_txt> ]]>


For now, you're correct in that the only thing you can do is not run GFN tasks on that computer.

The 64-bit genefer code requires at least SSE2, so I wonder if that is also true of the x87 80-bit CPU app? If so, then that would be the answer as the Athlon(tm) XP 1800+ has only SSE.
