MPI_Reduce (send_buf, recv_buf, data_type, OP, root, comm)MPI, [mpi-using] [mpi-ref] the Message Passing Interface, is a standardized and portable message-passing system designed to function on a wide variety of parallel computers. The standard defines the syntax and semantics of library routines and allows users to write portable programs in the main scientific programming languages (Fortran, C, or C++).MPI_Iprobe. Performs a non-blocking test for a message. The “wildcards” MPI_ANY_SOURCE and MPI_ANY_TAG may be used to test for a message from any source or with any tag. The integer “flag” parameter is returned logical true (1) if a message has arrived, and logical false (0) if not. For the C routine, the actual source and tag will be ...MPI is a directory of C++ programs which illustrate the use of the Message Passing Interface for parallel programming. MPI allows a user to write a program in a familiar language, such as C, C++, FORTRAN, or Python, and carry out a computation in parallel on an arbitrary number of cooperating computers. Overview of MPIThe prototype for MPI_Reduce looks like this: MPI_Reduce( void* send_data, void* recv_data, int count, MPI_Datatype datatype, MPI_Op op, int root, MPI_Comm communicator) The send_data parameter is an array of elements of type datatype that each process wants to reduce. The recv_data is only relevant on the process with a rank of root. Tutorials and books on MPI. A helpful online tutorial is available from the Lawrence Livermore National Laboratory.
