Subject: Re: [OMPI users] Best way to reduce 3D array
From: Ricardo Reis (rreis_at_[hidden])

  If using the master/slace IO model, would it be better to cicle through
all the process and each one would write it's part of the array into the
file. This file would be open in "stream" mode...

  like

  do p=0,nprocs-1

    if(my_rank.eq.i)then

      openfile (append mode)
      write_to_file
      closefile

    endif

    call MPI_Barrier(world,ierr)

  enddo

  cheers,
