7 行行文用行 If ( rank == 0 ) { // 0 } else if (rank == 1) { // 1 }

8 MPI_Send() MPI_Recv() 非 MPI_Isend() MPI_Irecv() 用 rank0 rank1

9 int MPI_Send(void *buf, int count, MPI Datatype datatype, int dest, int tag, MPI Comm comm) void *buf int count MPI Datatype datatype int dest int tag 用 MPI Comm comm

10 public void Send<T>(value, dest, tag) value int dest int tag 用

11 int MPI_Recv(void *buf, int count, MPI Datatype datatype, int source, int tag, MPI Comm comm, MPI Status *status) void *buf int source MPI ANY SOURCE int tag 用 MPI ANY TAG MPI Status *status

12 public T Receive<T>(source, tag) int source int tag 用

13 int MPI_Isend(void* buf, int count, MPI Datatype datatype, int dest, MPI Comm comm, MPI Request *request) MPI Request : 非子用 int MPI_Irecv(void *buf, int count, MPI Datatype type, int source, int tag, MPI Comm comm, MPI request *request)
