The MPI_Alltoall is an extension of the MPI_Allgather function. Each process sends distinct data to each of the receivers. The j th block that is sent from process i is received by process j and is placed in the i th block of the receive buffer. Syntax c++ See more Returns MPI_SUCCESSon success. Otherwise, the return value is an error code. In Fortran, the return value is stored in the IERRORparameter. See more All parameters are significant on all processes.
