I am running GIMPS on its own; because there was an indication on its homepage that SRBase could utilize my GPU, I installed BOINC, this project, and OpenCL AMD APP SDK 3.0 -- what else do I have to do to run SRBase using my GPU? Both GIMPS and you are laboring under the misapprehension that a message board is a list of frequently asked questions. I'd like to run GIMPS using my CPU (since it doesn't appear to utilize my GPU) and SRBase using my GPU simultaneously; can I do so? I'm using an AMD 3400G with a fairly powerful, integrated GPU.

In your account settings under Preferences for this project enable ATI + Nvidia. CPU TF was not setup and planned only GPU.

Those radio buttons (ATI and Nvidia) were already checked in the project's preferences when I looked. "TF"? There is a telegraphic reference to a path with regards to OpenCL -- all I've done is install and run this project under BOINC, then install AMD's SDK 3.0 (from Softpedia, AMD reportedly having withdrawn it) while it was running. Having done so (and completed several work units since), should SRBase now detect my GPU and switch computation to it automatically, or do I need to do something else? My CPU is at full capacity and my GPU is idle. I haven't rebooted -- I'll try that and edit this or report back if computation switched to my GPU.

Check also in BOINC client the prefs, Use GPU while computer is in use, also check the event log if your GPU is recognized.

I just now spotted the advanced view -- the suspend GPU option is not shown in the default view (it should be, or at least be deselected by default) -- computation is now taking place in my GPU. Thanks.

I spoke too soon -- in Windows Task Manager, it appears that Prime95 never exceeds ~48% CPU usage if BOINC is running. I get how due to the vagaries of Windows, giving Prime95 a priority of 10 doesn't result in it getting any more cycles, but none of the available settings in Prime95 or BOINC seem to alter the fact that Prime95 won't utilize more than half of available processor time if BOINC is running. I tried giving BOINC just 1 thread and 1% of available CPU time and I tried giving it all 8 threads and 100% of CPU time; processor utilization varies, but rarely approaches the over 90% it does running Prime95 alone. HWInfo shows my GPU utilization at 100% (though Task Manager seems to think the GPU is idle). I'm still looking for a means of getting SRBase to use my GPU without (significantly) interfering with Prime95.

Hi there. Prime95 will always force you to not run all threads on your cores for better performance even when you set it on local.txt file. It is not recommended to use HT for PRP/LLR, only for factoring on CPU.
