Find Nearest GPU (NVIDIA) Device

Little program that makes use of HWLOC bindings into CUDA-driver/-runtime to find the nearest CPU (NUMA) to the GPU device(s).

Can be useful for configuring systems that bind to CPUs/Cores using some index value.

Compile

Requires CUDA 10+ and HWLOC v2, uses CMake to generate the build system:

$ mkdir build && cd build
$ cmake ..
$ make
$ ./nearest-gpu

Where Used

SLURM

Use to set the gres.conf for each GPU device, example of what this looks like:
