[mpich-discuss] MPI IO, reading MPI Writes without MPI read

[Ryan Crocker]

So i'm not sure if this is crazy or not, but i have file outputs from my code that write ensight gold files in MPI.  Here is the write, 

  disp = 3*80+4+0*ncells_hexa*4
  call MPI_FILE_SET_VIEW(iunit,disp,MPI_REAL_SP,fileview_hexa,"native",mpi_info,ierr)
  call MPI_FILE_WRITE_ALL(iunit,buffer3_hexa(:,1),ncells_hexa_,MPI_REAL_SP,status,ierr)

if i wanted to read that in binary in fortran, or C (preferably fortran) what exactly would i need to do?  I can't seem to write code that reads these in and produces anything that looks like the plot i get in paraview.  I know that MPI write puts out each processor data vector with that disp in between them, but i just can't make that structure make sense to me when i try to read it in.

Thanks for the help,
