Simulation library in Python

[Samir Patel]

For last couple of weeks, I was doing lot of research
on various simulation libraries. Only one I find in
python is http://simpy.sourceforge.net. It is very
powerful, but it seems that it does not have any
active development. I am sure there are more than
that. Where are they?

If one wants to create a new simulation program, what
are different packages to use:
simulation event list - priority queue?
simulation model creation (preferable data flow) -
dia, Pyut, OGL
reports - http://reportlab.com

http://docutils.sourceforge.net/

graph -

http://navi.picogui.org/svn/misc/trunk/rtgraph/

http://matplotlib.sourceforge.net/

animation - Blender?, VTK, VPython
cad - http://pythoncad.sf.net
GIS - ?
Storage - ZODB
Import/Export - ?

I am interested in creating a professional level
simulation model in Python, so any help regarding this
will be very much appriciated.

sketch, maybe.

*Lots* more. More than you can shake a stick at... But, when I was
using them, I never found any free graph plotting libraries that did
everything I wanted (Python or no Python). It's a hard thing to do
well.

Pygame.

I think Bernhard Herzog has released some free GIS code in Python
recently. And IIRC, Fredrik Lundh sells GIS code of some kind.

xsdb (very new, though). Plus of course, all the usual relational
suspects, and Gadfly, Sleepycat BSDDB (in standard library), etc.

- of what?

I think Simpy is about as close as you're going to come - it's the best
I've seen in Python. I haven't tracked it lately but if you send a note
to the developers I think that you'll find they're still active.

Personally, I (and the group of which I'm a member) are doing our
modeling in C++/CSim. It's mostly a speed of simulation issue but I
have to admit that I haven't done any comparisons between the C++/CSim
and Simpy. I'm just assuming that the compiled nature of C++ and the
interpreted nature of Python will give the edge to C++. Our models can
run for a long time so speed of execution is important. If anyone has
information to the contrary, I'm all ears. (or eyeballs, or something)
