 ## Usage
 
-NCCL follows the MPI collectives API fairly closely. Before any collectives can be called, a communicator object must be initialized on each GPU. On a single-process machine, all GPUs can be conveniently initialized using `ncclCommInitAll`. For multi-process applications (e.g., with MPI), `ncclCommInitRank` must be called for each GPU. Internally `ncclCommInitRank` invokes a synchronization among all GPUs, so these calls must be invoked in different host threads (or processes) for each GPU. A brief single-process example follows, for an MPI example see src/mpi_test.cu. For details about the API see nccl.h.
