+.SS Usage tips
+.sp
+Since the tools are MPI applications, it helps to keep a few things in mind:
+.INDENT 0.0
+.IP \(bu 2
+One typically needs to run the tools within a job allocation.  The sweet spot for most tools is about 2\-4 nodes.  One can use more nodes for large datasets, so long as tools scale sufficiently well.
+.IP \(bu 2
+One must launch the job using the MPI job launcher like mpirun or mpiexec.  One should use most CPU cores, though leave a few cores idle on each node for the file system client processes.
+.IP \(bu 2
+Most tools do not checkpoint their progress.  Be sure to request sufficient time in your allocation to allow the job to complete.  One may need to start over from the beginning if a tool is interrupted.
+.IP \(bu 2
+One cannot pipe output of one tool to the input of another.  However, the –input and –output file options are good approximations.
+.IP \(bu 2
+One cannot easily check the return codes of tools.  Instead, inspect stdout and stderr output for errors.

+.SS Examples and frequently used commands
+.sp
+If your MPI library supports it, most tools can run as MPI singletons (w/o mpirun, which runs a single\-task MPI job).
+For brevity, the examples in this section are shown as MPI singleton runs.
+In a real run, one would precede the command shown with an appropriate MPI launch command and options, e.g.,:
