[Swift-devel] How to do coasters on bgp?

[Ioan Raicu]

I believe the BG/P is one of those machines, where static resource 
provisioning is necessary. From the discussion we had on static vs. 
dynamic provisioning a week or so back, I think that might be a big 
hurdle (besides the other typical hurdles, such as network connectivity, 
language support, and nuances specific to the BG/P). Before moving to 
the BG/P, I'd argue for implementing static provisioning, where one 
could specify N nodes/cores for H hours, all contained in a single LRM 
job submission. Once that works in general, on your favorite LRM, then 
I'd move to the BG/P, and tackle BG/P specific issues.
