Config suggestions for a RTX 3080?

I know this is going to vary a lot per user and am not expecting a fully complete, out-of-the-box solution. But I wonder if I could get more work out of my 3080 with a few tweaks?

 

Currently I have the four E-Cores on a 12700F reserved for Einstein work only. (I run CPU tasks on other projects like Universe.) I tried reserving P-cores but it doesn't seem to change GPU utilization much; by that I mean Afterburner reports the GPU seems to be taking a walk in the park, I've never seen its temp exceed 62 degrees.

I selected the following apps:

- MeerKAT--because I read this one uses mostly GPU

- Gamma-ray Pulsar binary search #1 (GPU)

- Multi-directional Gravitational wave on O3 (GPU)

I set 0.2 utilization for BRP apps, 0.2 for FGRP and 0.5 for GW--this is because I only have 16gb memory total, and the O3 tasks want to use 4 gb each... I'll revisit this setting once I upgrade to 32 gb.

 

Does anyone want to offer suggestions of what I could improve in the meantime?

I'm not crunching for glory but I figure my config is probably what a newbie comes up with so there should be room for easy improvement in there. :)

Thanks.

This is what I am using on

This is what I am using on one of my rtx 3080 ti boxes.

I do NOT know what settings are appropriate on a P/E core CPU.

YMMV (Your mileage may vary)

You haven't made your computers visible (they default to hidden).  Seems like a Linux-based rtx 3080 should be able to manage 2M+ RAC.  A windows one is usually a little slower.  But you should still be able to get a very respectable RAC out of your system.

You can also run FGRPB1G with 1 CPU usage.  And the other two with 0.9 CPU usage.  FGRPb1G will run two tasks faster than one task (divide a two task time by 2 to compare with a single task time). I think the other two apps its more of a wash between a single task and two tasks.  But running them 2 at a time allows a mix and match of processing the GPU tasks.
