The syntax of the blocking send operation is given below.
| MPI_SEND(buf, count, datatype, dest, tag, comm) | |
| IN buf | initial address of send buffer (choice) |
| IN count | number of elements in send buffer (nonnegative integer) |
| IN datatype | datatype of each send buffer element (handle) |
| IN dest | rank of destination (integer) |
| IN tag | message tag (integer) |
| IN comm | communicator (handle) |
int MPI_Send(void* buf, int count, MPI_Datatype datatype, int dest, int tag, MPI_Comm comm)
MPI_SEND(BUF, COUNT, DATATYPE, DEST, TAG, COMM, IERROR)
<type> BUF(*)
INTEGER COUNT, DATATYPE, DEST, TAG, COMM, IERROR
The blocking semantics of this call are described in Sec. Communication Modes .
