Thanks for the lead to Proactive.  I'll take a look at it.



Most of my work these days is in biological modeling, which means ~100s

of thousands of relatively homogenous agents per simulation.  Coarse

grained simulation (the kind manageable by "shell scripts and rsh",

though I prefer MPI) has worked for me so far.  But, I'm about to embark

on a project that might require a much more fine granularity, or more

accurately multi-grain hierarchical agents.  I'm just looking for an

evolutionary path to bridge from the current grain to the finer grain.
