[mpich-discuss] writing results of a parallel code in a single txt file

[Jeff Hammond]

are you using MPI-IO?  if not, i don't see how this question belongs
on the MPICH discussion email list.

with the information you have provided, i conclude that you have
written an incorrect parallel program and not that there is anything
wrong with MPI.
