GRID A100X not using full power

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

GRID A100X not using full power

Postby luckenbach » Mon Sep 07, 2020 9:06 am

I've noticed that my DGX a100 is not using full power of the GRID A100X cards and wondered if this is an opencl/nvidia driver thing. here is my nvidia-smi output from inside of the FAH container.

Welcome to the F@H Forum luckenbach,

Can you please post the log file? Ensure you include the first 100 lines which will inform us of what the system configuration is and what the client settings are. If you require guidance, please view this topic: viewtopic.php?f=24&t=26036

Please note the on high-end GPUs, if you're folding a small WU, then the power consumption would be low since the GPU isn't being fully utilized. Moreover, F@H makes use of specific GPU components which means that other components aren't being used so less wattage would be recorded. If you provide the log files as above, we can shed more light on your situation :)
ETA:
Now ↞ Very Soon ↔ Soon ↔ Soon-ish ↔ Not Soon ↠ End Of Time

Welcome To The F@H Support Forum Ӂ Troubleshooting Bad WUs Ӂ Troubleshooting Server Connectivity Issues

Re: GRID A100X not using full power

That is the first 200 lines of the logs, i will note that I did end up slotting up the CPU into 16 core slots leaving around 32 cores for 'not folding' tasks.

Hi!

We're super thrilled to have powerful GPUs like A100X pitching in!

The current 134xx projects for the COVID Moonshot perform well on the A100, but the systems aren't quite large enough to fill up the entire GPU to achieve full utilization. We're making some improvements in core22 over the next few weeks that you should keep an eye out for that will improve utilization substantially, and eventually we will be able to allow multiple simulations to take advantage of Ampere's multi-task scheduling to completely fill up the whole GPU.

I think you're the first volunteer with an A100 I've worked with, so if you'd like to be pulled into testing the latest core22 variant, send me a private message with your email and we'll rope you in!

Thanks again for contributing, and for bearing with us!

Hello John! :)

This is sort of off-topic I'm afraid (sorry sorry!), but I was wondering if you could quickly say if maybe these utilization improvements would also apply to AMD Vega architecture, as I think my Vegas should be able to give more than the appx 1.2M PPD or so they currently yield even with these large moonshot WUs you're handing out nowadays.

Thank you!

@FaaR: A few bugfixes for AMD Vegas will go into core22 0.0.12, so we're hoping that you'll see improved PPD too!
