1) Message boards : Number crunching : How to force opencl on nvidia? (Message 6838)
Posted 19 Nov 2015 by bzaborow

I have a GTX960 card, I run linux64bit. For some reason I still get 1.03 CUDA3.1 app for this card automatically. How to force a 1.04 opencl app for nvidia? This thread: suggests it may boost performance. If an only option is app_info.xml, can I ask for a template?

I've changed GPU from a geforce to radeon HD7770 few days ago and since then I get always computation errors on GPU WUs. Stderr output from task says:

[Sep 18 15:44:40 UTC] 1 cruncher has been started.
[Sep 18 15:44:40 UTC] Core compilation failed. Exiting.
[Sep 18 15:44:40 UTC] Core compilation failed. Exiting.
[Sep 18 15:44:41 UTC] *Break* Shutting down...
[Sep 18 15:44:41 UTC] Core compilation failed. Exiting.

(full output:

The cruncher is restarted 10 times and every time it fails.

What may be the cause of those errors? I run other boinc projects which use GPU (Collatz, Milky Way) and they compute correctly.
My video driver is catalyst 12.6. I use 64bit linux.

Or maybe it is an upstream problem with dnetc?

it is an upstream problem with radeons 7xxx:
3) Questions and Answers : Unix/Linux : CPU units getting errors (Message 1087)
Posted 25 Sep 2011 by bzaborow
I get similar errors on CPU units, however only and allways when I suspend the tasks. Nvidia units suspend correctly. The tasks seem not to respond to some signals from boinc (after suspend request they still run and consume CPU, while boincmgr shows "computation error" status, I had to kill them manually).

my boinc version: 6.12.33 (linux), dnetc version - 1.02 (downloaded automagicaly by boinc)
