Good that you found your way to the list. Now tell us what new hot
projects are up and running at Sarovar ;)

AFAIK, the Supercomputer that may be a cluster of 1000+ individual
computers appears as a single system to its system administrator/end
user.  Chaos like applications manage your other applications. (
http://www.purehacking.com/chaos/ ) We could be using OpenOffice,
Postgres or  any other application as we would on any other system. 
This much I digressed from AB, and also, once I get my hands on such a
machine, I'll update more details :)

Marvin Minsky pronounced AI to be "brain-dead" some time back, but
that is not the same as being stupid :)
