036 Run a MoML model over and over again.
037 This class reads in a MoML file and executes it over and over again.
038 The time and memory usage stats are printed on stdout.
039
040 For example to run a model 100 times:
041 <pre>
042 cd $PTII/ptolemy/actor/gui/test
043 java -classpath $PTII ptolemy.actor.gui.test.Rerun ../../lib/test/auto/Sinewave.xml
044 </pre>
045
046 To run the model 10 times:
047 <pre>
048 java -classpath $PTII ptolemy.actor.gui.test.Rerun 10 ../../lib/test/auto/Sinewave.xml
049 </pre>
050
051 To create a ptplot file of the times and memory:
052 <pre>
053 awk '{  t[NR] = $1;
054 m[NR] = substr($4, 0, length($4) - 1);
055 f[NR] = substr($6, 0, length($6) - 1);
056 }
057 END {  print "dataset: time (ms)";
058 for (i=1;i&lt;=NR;i++) {print i, t[i]};
059 print "dataset: memory (K)";
060 for (i=1;i&lt;=NR;i++) {print i, m[i]};
061 print "dataset: free (K)";
062 for (i=1;i&gt;=NR;i++) {print i, f[i]};
063 }' /tmp/t &gt; /tmp/t.plt
