Information about the GPU

• nvidia-smi is a command line tool.
• cudaDeviceProp data structure is a data structure which you can use from your CUDA program. An example is static.cu to read static properties of the GPU like compute capability, number of SMs, memory sizes, etc.
• Nvidia Management Library(NVML) is a library which you can link to your CUDA program. An example how to use it is dynamic.cu to read dynamic properties of the GPU like current temperature and clock frequency at runtime. Link with /usr/local/cuda/targets/x86_64-linux/lib/stubs/libnvidia-ml.so or simply flag -lnvidia-ml
