Hi !

Running the program shown below leads to an output which changes
randomly. All the processes print a rank between 0 and 2.
I tried it on 1 -8 processors on a SGI Power Challange. 
Does anybody know what might be wrong ??

The program is:


      program main

      implicit none
      include 'mpif.h'
      integer  myid, numprocs, rc, ierr
c
      call MPI_INIT( ierr )
      call MPI_COMM_RANK( MPI_COMM_WORLD, myid, ierr )
      call MPI_COMM_SIZE( MPI_COMM_WORLD, numprocs, ierr )
c
      write(*,*) 'Process ', myid, ' of ', numprocs, ' is alive'
c
      call MPI_FINALIZE(rc)
      stop
      end


Thanks for your support,

	Jan
