Is there a way to limit the GPU usage? #387

Open GoogleCodeExporter opened 9 years ago

What i want is to limit the usage of GPU from pyrit to something like 80%. The 
reason is that after some time the gpu starts showing artifacts. I dont have 
temp problems. The higher temp was 60°C. It'not much.

no, you can't limit usage with any of OpenCL, Calpp or Cuda implementations.
when computing, you should also shutdown your X server.
closing X you'll free some other resources also...
(what do you want to do? playing games and computing pmks at the same time?)
read about OpenCL at khronos

Of course i dont want to play games while computing pmks...  

The artifacts appeared with the X server *down*, that is why i asked.
It thought it was weird. THe problem occured after ~40m.

maybe telling something about which implementation gives you artifacts? 
(OpenCL|Cuda|Calpp, driver version, gpu model, are you telling nothing...)
did you noticed something wrong in your dmesg, or /var/log/messages?
maybe acpi wants to do some powersaving and gpu is driven by pyrit...
