I was wondering if I am the only one that has this problem running GPUGrid?

I definitely have the option for "Use GPU when Computer in use" unchecked, but I often notice that GPUGrid is still in use even though I am using the computer. All the CPU BOINC applications that I run stop immediately. The reason that I can tell when the GPU hasn't stopped is because my screen is slow and jerky to update when using the computer. When I open the BOINC Manager, the elapsed time for GPUGrid continues to count up etc.

The only way to stop it is to shut down the BOINC application and run it again.

Any suggestions of how I can fix this or is it a known bug?

Bump! Anyone having the same experience?

I've noticed something similar
Actually, GPUGRID does seem to stop running on BOINC in the sense that the percentages do not increase at all while the checkbox is unchecked, but I have a feeling the app is still hogging the GPU.

Could it be that some of the GPU ressources are not entirely freed by BOINC when the box is unchecked? I get poor graphics performance when unchecked, and it improves significantly if I kill the application.

My guess is that unfinished running portions of the WU, the ones that were being calculated in the GPU before unchecking the box, are still stored in GPU memory to avoid losing a couple percentages. I'd rather have it flush the GPU completely... I did notice that closing and re-opening the app at that time mathe tasks lose about 1% which maks me believe that this "pause" mode is not entirely transparent for the rest of the system

Just my 2 cents, I have no idea how BOINC and GPUGRID work together ;)

If you have set Computing Preferences:

Leave applications in memory while suspended?
(suspended applications will consume swap space if 'yes')

to be yes then that would explain the second scenario ... not sure about the mifiring on the original suspend though.

hey, thanks, I didn't even see that option.
Makes sense now!
