GPUInformation

This code prints some relevant information regarding the GPU capabilities. If multiple GPUs are available, it prints the information of all GPUs.

Generally, this tool is an extremely dumbed-down version of nvidia-smi, but some of the queries might be useful to use in actual cuda code, e.g. when calculating the number of blocks and the threads/block.

Build with

$ nvcc GPUInformation.cu -o gpu_information

or use the provided CMakeLists.txt.
