I'm really in favor of ditching the PMPI layer and putting something better there.

I wouldn't go that far - the PMPI interface idea has been very successful and extremely useful and has lead to significant tool support. I think getting rid of it would be a huge setback.

I'm sorry; I was typing hastily while closing up my laptop and boarding a plane. I certainly don't mean deleting PMPI from MPI-4. I mean putting something better in MPI-4 that, over time, can replace PMPI (so that PMPI *can* be deleted in some future version). -- Jeff Squyres [email protected] For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
