Help..My gpu client load's fluctuate..

post #1 of 9
Thread Starter 
Hye guys..
recently i have set up my rig i5 2500K to run bigadv on linux VMWare
while my gtx 460 folds on windows..all client running well until i realize the
gpu load wont maintain at 99% all the time, it fluctuate continuously..

Is this because VMware use all the core and ram for bigadv which cause this problem to occur, i can still finish the gpu WU without error but at longer tpf..
more details in the screenshot below..

Might not be the exact reason but its what i have come up with as i have the same problem running VM bigadv and v7 GPU clients at the same time. The GPU gets slowed down by some 30sec TPF.

i tried using v7 client, v6.41 and FAH Gpu Tracker..all give the same result, the loads will continuously fluctuate..same result when run at stock and OC speed..
i love sub 1minute 30second tpf but now i getting 2minute tpf..

Yeah, it looks like your GPU isn't getting the resources it needs from the CPU to run at 100% continuously. This also means that the CPU is giving up some of its bigadv time in order to take care of the GPU, meaning both clients have higher TPF. I don't fold bigadv myself, but I would try comparing your total PPD with and without the GPU folding.

Also, if you enable -advmethods on the GPU, you can get WUs that rely a lot less on the CPU, meaning better PPD when both clients are running. (Not sure whether the 460 qualifies for this though.)

Did you ever have the GPU client running alone without the VM going? Was the usage steady at that point?

Something you may try, use task manager and change the priority of the VM down a notch, or increase priority of the GPU client and see if that makes any difference..

for bigadv alone i get around 26k ppd at 32.24 minute tpf,
bigadv + gpu i get around 33k ppd with 34minute tpf and 2minute tpf respectively.

Before i ran bigadv, i have fold smp+gpu client for several days..the gpu loads 99% steadily on overclock speed..
i will give it a try, thanks for the suggestion..

Ok good stuff Now, the only remaining issue is that changing priorities in task manager is only temporary. To permanently have the priorities set the way you want, you will need to look into something like this: Prio - Priority Saver
