This package adds support for CUDA tensor types, that implement the same function as CPU tensors, but they utilize GPUs for computation. It is lazily initialized, so you can always import it, and use is_available () to determine if your system supports CUDA.

NCCL can be easily used in conjunction with MPI. NCCL collectives are similar to MPI collectives, therefore, creating a NCCL communicator out of an MPI communicator is straightforward. It is therefore easy to use MPI for CPU-to-CPU communication and NCCL for GPU-to-GPU communication.
