I think you need to keep this.	The -n seems a requirement for a valid test
result.

-# pdsh args required to instantiate all instances of IOR in parallel
-# the chosen module must support ''-n <procs-per-node>''
-# -R<module>, -f<fanout> etc
-pdsh_mpiargs="-Rmqsh"

You can change
pdsh=pdsh
to
pdsh="pdsh -R ssh"
but maybe ssh doesn''t support -n.

Doesn''t this:
       chunk=`count_range $range`
-	if ((chunk > n)); then
+	if ((chunk > $n)); then
need to be 
+	if (($chunk > $n)); then
(similar question everywhere)

I don''t know that you can assume sudo
+					sudo /bin/bash -c echo clear ">" $LRU;
\

I think we need the -n here for valid results.
-		    $pdsh -S -b $pdsh_mpiargs -w "$test_clients" -n $ntask >>
$tmpf 2>&1 \
+		    $pdsh -R ssh -S -b -w "$test_clients"  >> $tmpf
2>&1 \
			"${cmdline[@]}"

You''ve hard-coded the task names -- this will only be right for this
specific
run.  It need to work for all values of clients_[lo|hi],
tasks_per_client_[lo,hi], etc.

print SCRFILE "set xrange [ -1 : 13 ]\n";
print SCRFILE "set xtics nomirror rotate ( \"Cli 1 Tasks 1

Also, the output files should depend on the value of tests, which users might
change.
tests=(write rewrite clear_cache read reread)

You must gather all this info from the details file (or test output)
