From 92a508bdb80fa3d1a9ce296c65c3d819f117fd22 Mon Sep 17 00:00:00 2001
From: Albert Cheng <acheng@hdfgroup.org>
Date: Tue, 13 Dec 2005 13:29:09 -0500
Subject: [svn-r11790] Purpose: Improvement

Description:
Some parallel system would dump some system messages in the stdout
stream of an MPI application.  That caused the output matching script
to fail unnecessarily.

Solution:
Added the STDOUT_FILTER feature to filter out those system messages
out of stdout result.

Platforms tested:
Tested in LANL Lambda.
