A question about that. Lets suppose I want to use a bproc based cluster
just to run parallel processes, like if it was a SMP box. No need of
load balancing and so on. Really I just need a local queue system on
master node, isn't it ? Just mantain a queue of programs, written
in MPI or just with bproc to do the spawns, and there it is. 

Ah, and about mpirun-mpiexec ? If I just run my MPI program and it
does an rfork() or thelike on init, no need for scripts that do
the spawning via [rs]sh, which looks like the main reason for mpirun.

Missed something ?
