Dear Corinne:

the debugger gdb can be used to run in batch mode.

gdb ./model_name

will go to the crash, but you can set breakpoints before that.

I wonder if it would not help to start with a working Batch swarm 
example?  Compare your approach with it?

Last Spring, I was teaching my graduate course on agent based modeling 
and decided to try to fix up the Swarm Sugar Scape to include a batch 
model and a parameter handler.  A couple of students did use this for 
testing and adding in new features, so I'm pretty sure it worked.  I 
mean, I can't test it now very much because I'm busy, but my 
recollection is that it did work, it runs now, and I don't think I would 
have packaged this up and given it to them if it did not work. 

I recall being quite proud of this at the time, and I cannot remember 
why I didn't publicize it to this list or such. 

Since it is a small file, I'm attaching it.  I hope you don't mind.
