I've got a 550TI and a 690 in one 6 core machine.

swan_sync = 0
BOINC 7.0.25
Win7, x64
On multiproc systems use 99%
Use at most 100%

GPUgrid grabs one thread for each of the 690 gpus but not for the 550.

What can I do to have GPUGrid run both cards?

Thanks,

Ken

use the option in cc_config.xml:

<use_all_gpus>1</use_all_gpus>

Thanks Rantanplan,

When I started boinc after creating the config it momentarily shows all 3 gpus with a task but then drops the third. A minute or so later the third device (device 2) picks up task then drops it. It fails with a "computation error".

I ran "update" but the pattern recurs.

I am also running WCG wus on this machine and they are using 10 threads.

After aborting 4 wus, it's now running.


Curious if you can explain what happened.
