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.

/home/rieffelj/src/voxcraft-sim/src/VX3/VX3_SimulationManager.cu(415): CUDA Func tion Error: too many resources requested for launch Running simulation locally by default. ./vx3_node_worker -i workspace/locally/20200731155914.vxt -o workspace/locally/2 0200731155914.vxr

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

That is a tautological diagnosis. Where in your code is it requesting too many resources?

Restarting sometimes resolves the issue, briefly. On Aug 1, 2020, 2:21 PM -0400, Liu Sida notifications@github.com, wrote:

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.
