GPU error when running node worker

[jrieffel]

I get the following printed to a history file when running vx3_node_worker. I have an NVIDIA Quadro K1200 (rev a2), and I'm using the custom CMake file for my GPU you provided in a separate thread.

1 GPU found.
=== set device to 0 for 1 simulations ===

Total GPU memory 4236902400 bytes.
Set GPU heap size to be 2118451200 bytes.

it says CUDA Func
tion Error: too many resources requested for launch.
i guess it's the reason.

[jrieffel]

That is a tautological diagnosis. Where in your code is it requesting too many resources? Restarting sometimes resolves the issue, briefly.

Thanks for all your hard work, voxcraft team! I think I was able to resolve the issue by booting my research computer into single user mode, thereby freeing up the GPU. Worth keeping this in mind for future resource-poor researchers!

Meanwhile, saving up for a Tesla..

@jrieffel if you document your process, we will share it as "voxcraft for resource-poor researchers" documentation.

Either way, we are looking forward to see how your lab uses voxcraft.

Keep the issues/pull requests/questions coming!
