[jsdl-wg] application profile proliferation

[Joseph Bester]

I've been reviewing JSDL, the BES HPC Application Profile, and JSDL  
Parallel/SPMD profile to see how they can be used with Globus GRAM  
execution service. One concern I have is the way these various  
application profiles are redefining the same basic functionality  
(executable, arguments, environment, etc), either in their own  
namespaces or importing from the jsdl-posix namespace, sometimes with  
different behavior/features. It's not clear to me how (if at all)  
these are to be/can be composed.

The feature set of GRAM seems to span these profiles: some (but not  
all) of the limits from POSIXApplication are relevant, as is the SPMD  
functionality of specifying the various process counts and something  
like SPMDVariation. There is also a small amount of scheduler- 
specific and site-specific extensions that GRAM might have to deal with.

Do other groups have plans for implementing more than one of these  
profiles, and what approaches are you considering for doing so?
