[Users] parallel program

[David Rideout]

Well there is a Cactus portal I understand, but am not too familiar
with this.  Perhaps someone else will elaborate.  If you have access
to a grid then perhaps you can use this to launch your jobs.

Cactus is designed to be extremely portable -- it runs on a large
variety of machines with different MPI implementations.  So I'm not
sure what limitations you refer to.

Cheers,
David
