Topic 226237

     Ive been running CPU W/Us on a new rig for about a month now. The CPU is a Ryzen 7 3800x. I have it running 50% of CPUs at 100% of the time. This is my daily driver so 50% works well.

 

     I have never run GPU W/Us and would like to set up to do both CPU and GPU (if that's feasible). My video card is a Nvidia GeForce RTX 3060. Is it just a matter of marking boxes (in E@H project tab) 'Use Nvidia GPU' and appropriate 'Applications'? Is it possible to set the GPU at 50% full time?

 

     Now... with the CPU W/U running I tried a higher % and paused when in use. Problem is, something is causing my machine to think its in use every 5-10 minutes. If I have the screen saver going it shuts that off randomly. That's why Ive been running things full time.

 

     Any pointers would be very much appreciated!

it's not possible (currently)

it's not possible (currently) to throttle the GPU in the same way that you throttle the CPU. it will use as much of the GPU as the science application is coded for.

if you run the Gamma Ray GPU application, you will use about 95+% of the GPU for nearly the entire run (with a few seconds of lower utilization during the FP64 portion at the very end of computation).

if you run the Gravitational Wave GPU tasks, they are more limited by the CPU since some portion of computation still takes place on CPU. GPU utilization will likely be a little lower, like 60-75%.

but you can't control or change these yourself. they will use what they need, no more, no less.

but the 3060 should provide a good boost to production, GPUs are many times faster and more power efficient that CPU crunching.

Can I run both GPU and CPU at the same time? Should I just stick with GPU W/Us?

As I said this is my daily driver and dont want to slow it down til its a pain to use...
