Stress Testing CPU and GPU - not enough power!!

[donpavlov]

I want to stress Test my CPU and GPU, but am currently limited by the tests not beeing demanding enough.

My setup:

• Intel Xeon 11xxx, Quadro RTX 5000, nvme SSD
• Ubuntu installation, mainly without a dedicated display.

My problems are the following:

• Running GPU Tests without a dedicated display is nearly impossible using pts.
  • Only Tests i found working and generating a bit of power usage: xsbench-cl, and lulesh
• Running both CPU and GPU Stress in parallel is not generating enough power usage on the GPU.

I can use the following non pts command on lulesh to make the gpu run under full load:

./lulesh -s 256 -c 10 -i 200

But if I run the following:

PTS_CONCURRENT_TEST_RUNS=20 TOTAL_LOOP_TIME=30 phoronix-test-suite stress-run lulesh-cl xsbench xsbench-cl

I can only utilize the gpu to 30-40%.

If i connect a display to the device, use startx to start the display server i though i might be able to run unigine: The machine is only accessible via ssh right now. If necessary usb and keyboard can be directly connected, but it is not desired.

DISPLAY=:0.0 phoronix-test-suite benchmark unigine-heaven

i get the following error:

 The test run did not produce a result.

Can somebody help me out here?
Either recommend a good test to run on the gpu or adjusting the options/commands i used.

Those particular GPU tests are rather crappy / old... gromacs v-ray luxcorerender and others are more real-world, demanding, and don't require display.

Gromacs sounds interesting.
But how can i run the latest gromacs with a gpu profile?
Or should i keep using gromacs-gpu?
