Subject: [OMPI docs] reorder mpi rank
From: Sean Ross-Ross (srossross_at_[hidden])
Date: 2008-01-09 19:05:32

Is there a way to reorder the mpi rank at runtime or otherwise?

I have a program that makes files on each local node in somewhat of a
random fashion. I want to these files to correspond to a part of a
PETSc Distributed array used in another software package. My problem
is that PETSc expects these windows of data to be on a certain
ranking node. It seems that an easy solution may be to change the
rank of the nodes to correspond with the PETc array.

Thank you for your help
~Sean
