Q. Functions employed for messaging passing?
The functions employed for messaging passing are:
int MPI_Send(void *msgaddr, int count, MPI_Datatype datatype, int dest, int tag, MPI_Comm comm.)
on return, msg can be reused instantaneously.
int MPI_Recv(void *msgaddr, int count, MPI_Datatype datatype, int dest, int tag, MPI_Comm comm.)
on return, msg comprises requested message.
MPI message passing can be either collective or point to point.
