I might be missing the point here, but DE is a timed domain, so a simulation runs for a particular amount of time. The DE Director a start time and a stop time, which can be synchronized to real time. The design doc at http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII1.0/ptII1.0/doc/design/design.pdf has the details. Now, if what you are tring to do is repeat the same simulation 1000 times, then that is a slightly different. Say your DE demo has a start time of 0.0 and a stop time of 100.0 and is not synchronized to real time. The DE Inspection demo is like this. I have some notes about how create a class called MoMLSimpleApplication that will read in a .xml file and run it. The notes are at http://ptolemy.eecs.berkeley.edu/~cxh/ptpub/filter.htm You could probably adapt that class so that you could run it from a command line. If your shell has the 'repeat' built-in, then you could do something like: repeat 2 $PTII/bin/ptinvoke ptolemy.actor.gui.MoMLSimpleApplication ptolemy/domains/de/test/auto/multirate.xml Or, you could hack up a shell script. Note that if the demo is graphical, then MoMLSimpleApplication might not automatically exit. This is probably a bug. One hack would be to try using the -test code that is in ptolemy.actor.gui.MoMLApplication that is supposed to kill the process after 2 seconds. You could also use a Timer.
