MPI_Reduce (send_buf, recv_buf, data_type, OP, root, comm)This function is non-local. Successful completion might depend on the existence of a matching receive function. This function can return before a matching receive function is invoked if the MPI implementation buffers the message. However, buffer space might be unavailable, or outgoing messages might not be buffered for performance reasons.
Using MPI with C. Parallel programs enable users to fully utilize the multi-node structure of supercomputing clusters. Message Passing Interface (MPI) is a standard used to allow several different processors on a cluster to communicate with each other.
