[Swift-devel] limiting simultaneous jobs using the local provider.

[Ben Clifford]

Is there a way to limit the number of jobs that will be executing 
simultaneously with the local provider? (or perhaps with swift as a 
whole?)

There are a few throttle parameters in the configuration file but I find 
them slightly confusing, and setting them all to 1 appears to not have the 
effect I want - I think I understand them to limit the number of jobs that 
will be in a particular internal gram 'in process of being submitted' 
state, rather than the total number of actually executing jobs.

My immediate motivation for this is because the fmri workflow (which runs 
up to the incredible number of four cpu intensive executables 
simultaneously) pretty much kills my laptop for other purposes whilst its 
running. I'd much rather be able to limit it to one (or perhaps two).
