Easy docker build and run

git clone https://github.com/wilicc/gpu-burn
cd gpu-burn
docker build -t gpu-burn .
docker run --rm --gpus all gpu-burn

You can pass build arguments to specify the CUDA version, the compute capability, and base image distro, e.g.:

docker build --build-arg CUDA_VERSION=13.0.0 --build-arg COMPUTE=75 --build-arg IMAGE_DISTRO=ubi8 -t gpu-burn .

Building

To build GPU Burn:

make

To remove artifacts built by GPU Burn:

make clean

GPU Burn builds with a default Compute Capability of 7.5 as specified on NVIDIA's CUDA GPU Compute Capability. To override this with a different value:

make COMPUTE=<compute capability value>

COMPUTE selects a single virtual architecture for the default -arch flag. For a fat binary targeting multiple architectures, or to opt into architecture-conditional (sm_90a) or family-specific (compute_100f) features, set COMPUTE= to suppress the default and drive the build entirely from -gencode flags via NVCCFLAGS:

make COMPUTE= NVCCFLAGS='-gencode=arch=compute_86,code=sm_86 -gencode=arch=compute_90,code=sm_90'

CFLAGS can be added when invoking make to add to the default list of compiler flags:

make CFLAGS=-Wall

LDFLAGS can be added when invoking make to add to the default list of linker flags:

make LDFLAGS=-lmylib

NVCCFLAGS can be added when invoking make to add to the default list of nvcc flags:

make NVCCFLAGS=-ccbin <path to host compiler>

CUDAPATH can be added to point to a non standard install or specific version of the cuda toolkit (default is /usr/local/cuda):

make CUDAPATH=/usr/local/cuda-<version>

CCPATH can be specified to point to a specific gcc (default is /usr/bin):

make CCPATH=/usr/local/bin

CUDA_VERSION and IMAGE_DISTRO can be used to override the base images used when building the Docker image target, while IMAGE_NAME can be set to change the resulting image tag:

make IMAGE_NAME=myregistry.private.com/gpu-burn CUDA_VERSION=12.0.1 IMAGE_DISTRO=ubuntu22.04 image
