Benchmarking AWS

[Eightvfx]

I've been running the benchmarks on AWS instances, and discovered a big problem: vraybenchmark linux can't see the nvidia GPUs on the g- and p- series machines. Anyone have any ideas?

Thanks!

OK, figured out the GPU problem - the instance I used didn't have CUDA on it (duh). However, I am still having problems with the GPUs.

On the p3.8xlarge and p3.16xlarge, I am getting the following error:

./src/ocl_tracedevice.cpp(1907) : CUDA error 700
CallStack (from HasCallStack):
error, called at src/lib/VRay.hs:155:91 in vraybench-1.0.8-IH0QNi1KrDm4hWP4n3RvTh:VRay

On the p2.8xlarge and p2.16xlarge they are rendering, but there is some sort of limit preventing the improvement in the speed (maybe a GPU number limit?):

Tesla K80 11439MB	3:00
Tesla K80 11439MB x8	0:30
Tesla K80 11439MB x16	0:30

I'll post the full benchmarks for all the useful AWS instances in a separate post once we have these working

Do you know what driver version are these GPUs using?

Here?s a dump of my Google Sheet GPU section. Probably won?t format nicely as I am on mobile.

Alright. The driver seems reasonably new. This error comes from the CUDA API and means "something went wrong". I would guess that it might not be V-Ray GPU, since the benchmark is running on many other machines without such problems.
Is updating/changing the drivers an option?

Best,
Blago.

Here's the result of updating the driver:

That?s really strange. Do you by any chance know if other CUDA apps run there fine?

Best,
Blago.

[Eightvfx]

Can you suggest something I can run through command line which would be a good test? I have been running Redshift but that is on a slightly different configuration (same base image, however).

If it runs fine, can you try to delete everything in %temp% and in %appdata%/NVIDIA*. If this doesn?t work, we might have to arrange remote session to see if we can help with anything. Is that an option?

Unfortunately sometimes bug in drivers can cause only specific workflows to not work, so I can?t promise anything yet.

Eightvfx, you can try running V-Ray Benchmark Next which has been released last month.
