Subject: Re: [OMPI users] MPI-IO puzzlement

what is the communicator that you used to open the file? I am wondering
whether it differs from the communicator used in MPI_Barrier, and some
processes do not enter the Barrier at all...


world, I only use one comm on this code.


    CALL MPI_file_open(world, TRIM(flname), &
          amode, MPI_INFO_NULL, fh, ierr)

I have run this code in other machines, with other configs and got no
problem. I'm running with all debug flags turned on but it just hangs
there without any feedback to me. I wonder if there is something I could
do to have some feedback.
