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
