1. Purely MPI. Start singletons (or smaller groups), and connect via
sockets using MPI_Comm_join. You can setup your own DNS-like service, with
the goal of having the independent MPI jobs leave a trace there, such
I'm afraid that won't work - there is no way for the job to "self assemble".
One could create a way to do it, but it would take some significant coding in
the guts of OMPI to get there.

However within my org I faced very strong opposition to allow passwordless
ssh or rsh. For security reasons we want to minimize the opportunities to
execute arbitrary codes on the db clusters. I don;t want to run other
