[Swift-devel] Falkon and Coaster support for MPI

[Ian Foster]

Ben:

I wasn't debating Falkon vs. Coaster, but raising this issue: as the  
primary motivation for supporting MPI jobs via multi-level scheduling  
sees to be the BG/P, then I think we need to think hard whether we  
want to spend scarce Swift/Coaster development resources on making  
Coaster support MPI on BG/P (a fairly specialized requirement).
