[FRIAM] FW: Distribution / Parallelization of ABM's

[Douglas Roberts]

I forgot to mention: the project that I am currently working on is named
MIDAS, funded by NIH (http://archive.nigms.nih.gov/research/midas.html).
One of our project teams just received a grant from the TerraGrid community
for 200,000 compute hours to develop a grid-aware version of EpiSims.  The
successful proposal for that grant can be found
here:http://www.friam.org/uploads/MMarathe.pdf

Regards,

--Doug
