MPI_Type_vectorCreates a vector (strided) datatype
#include "mpi.h" int MPI_Type_vector( count, blocklen, stride, old_type, newtype ) int count; int blocklen; int stride; MPI_Datatype old_type; MPI_Datatype *newtype;
|count||number of blocks (nonnegative integer)
|blocklength||number of elements in each block
|stride||number of elements between start of each block (integer)
|oldtype||old datatype (handle)
- new datatype (handle)
Notes for FortranAll MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK) have an additional argument ierr at the end of the argument list. ierr is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the call statement.
All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGER in Fortran.
