I am relatively inexperienced in PVM culture and have questions...
We are considering purchasing an IBM J-30 SMP. Could anyone offer
opinions on the general applicability or feasibility of running PVM
apps on this type of K way SMP? I'm particularly interested in how
one maps particular CPU nodes to given execution instances, 
assuming one can do this via startup directives,or that the PVM
daemon "automatically" does this.
 
Has anyone had any experience in running the IBM SMP in "single image"
mode, and if so--does this imply that the user has shell level control
over how simple command shells are mapped to particular CPU nodes.

If PVM is considered a un-feasible or sub-optimal scheme for deploying
"parallel" jobs on an SMP, does MPI generally offer conceptual and/or
structural advantages?

thanks in advance for any opinions...

regards,
joe glassy
