2015-01-14 · • Wildcards are allowed in C and Fortran – src can be the wildcard MPI_ANY_SOURCE – tag can be the wildcard MPI_ANY_TAG – status returns information on the source and tag – Receiver might check status when wildcards are used mpi_send (data, count, type, dest, tag, comm, ierr) mpi_recv (data, count, type, src, tag, comm, status, ierr)
MPI的点对点通信包括阻塞式和非阻塞式：. 阻塞式通信调用 MPI_Send/MPI_Recv. MPI_Send不会返回，调用MPI_Send发送数据的进程会被阻塞，直到缓存为空. MPI_Recv不会返回，调用 MPI_Recv接收数据的进程会被阻塞，直到缓存被填充.

In Fortran, MPI routines are subroutines, Different types in Fortran and C, correspond to languages basic types MPI_Send(array[0], 1, subtype, 0, 123, MPI_COMM_WORLD);. Rank 0: original array. MPI_SEND does not complete until buffer is empty (available for reuse). – MPI_RECV MPI Send-Receive Struct: General mixed types (for C structs etc.) .

MPI_Send will not return until you can use the send buffer. may or may not block (it is allowed to buffer, either on the sender or receiver side, or to wait for the matching receive). Best How To : Whether you have to write a complex data structure to a file or over the network in MPI, the issues are the same; you have to extract the data into "Plain Old Data" (POD), save it, and then output it, and likewise be able to unpack the saved data into the same sort of structure. Broadcasting with MPI_Send and MPI_Recv. At first, it might seem that MPI_Bcast is just a simple wrapper around MPI_Send and MPI_Recv.

MPI_Sendrecv совместима с MPI_Send и MPI_Recv, т.е может "общаться" с ними.
