Hi Gilles, Thank you very much for your answer. I modified the code and it worked!
Here is the modified code: program main use mpi integer myid, numprocs, ierr integer comm1d, nbrbottom, nbrtop, s, e, it call MPI_INIT( ierr ) call MPI_COMM_RANK( MPI_COMM_WORLD, myid, ierr ) call MPI_COMM_SIZE( MPI_COMM_WORLD, numprocs, ierr ) ! call MPI_CART_CREATE( MPI_COMM_WORLD, 1, *[numprocs], [.false.]*, .true., comm1d, ierr ) ! call MPI_COMM_RANK( comm1d, myid, ierr ) call MPI_Cart_shift( comm1d, 0, 1, nbrbottom, nbrtop, ierr ) ! call MPI_FINALIZE(ierr) end program Best regards, Hector On Tue, Oct 6, 2015 at 4:30 PM, Gilles Gouaillardet < gilles.gouaillar...@gmail.com> wrote: > Hector, > > numprocs and .false. are scalars and MPI_Cart_create expects one dimension > array. > can you fix this and try again ? > > Cheers, > > Gilles > > > On Wednesday, October 7, 2015, Hector E Barrios Molano <hect...@utexas.edu> > wrote: > >> Hi Open MPI Experts! >> >> I'm using OpenMPI v1.10.0 and get this error when using MPI_CART_CREATE: >> >> simple.f90(10): error #6285: There is no matching specific subroutine for >> this generic subroutine call.
