Hey  there,

So I'm currently running O3AS1 (Previously was running O3ASE) and something I've noticed is that my gpu is (according to task manager) hardly used at all? "einstein_O3AS_1.00_windows_x86_64__GW-opencl-nvidia.exe" is running in task manager but it utilizes more cpu then it does gpu, which for cpu is overall about 20-30% and for gpu only about 2-5%. My pc does seem to be working and heat up but task manager still displays this low overall usage. The tasks are being completed in a timely manner and quickly despite this?

After going deeply into it, if you specifically switch task manager to look only at CUDA usage, it starts to show 99-100% but this for some reason does not affect the overall gpu usage? Can anyone pls explain this?

Thanks!

Aver

 

Additional: I run only Nvidia Gpu tasks and not cpu.

Task Manager defaults to

Task Manager defaults to showing 3D video usage on gpus.  But crunching BOINC on gpus uses none of the 3D video engines on gpus.  Hence the 0% usage showing.

You switch to viewing CUDA usage is the correct way to use Task Manager for gpu crunching monitoring.

Nothing is wrong.

Most of us don't rely on

Most of us don't rely on Windows Task Manager for GPU monitoring.  I think two of the favorite applications used for that purpose by Windows people posting here are:

HWiNFO

GPU-Z

Neither one is flawless, but either one can likely give you quite a bit of information on how your GPU is running.
