</h3>
<div class="Unindented">
A good way to run steps in parallel within a single test, especially when there are following steps, is to use the Unix Make utility. Writing Makefiles is beyond the scope of this document but here is a minimal example that will run “runsim cpu1” and “runsim cpu2” in parallel. For more information on make try “info make” at the Linux command prompt.

<div class="listing">
<pre class="listing">#!/bin/tcsh -x

# run the cpu1 and cpu2 simulations in parallel. 
# The -j parameter tells make how many jobs it may run in parallel

make -j 2
