[ogsa-wg] Paper proposing "evolutionary vertical design efforts"

[Ian Foster]

Dear All:

The most important thing to understand at this point (IMHO) is the scope of 
this "HPC use case," as this will determine just how minimal we can be.

I get the impression that the principal goal may be "job submission to a 
cluster." Is that correct? How do we start to circumscribe the scope more 
explicitly?

Ian.
