Re: [ogsa-bes-wg] Questions and potential changes to BES, as seen from HPC Profile point-of-view

Yes, GRAM users often (almost always) provide their own executable, either because they are CS-inclined, or because the "user" for GRAM is actually another piece of middleware that provides the more abstract interface you describe. BTW, this point of Peter's is what I thought everyone was talking about regarding heterogeneous resource descriptions, and that is what I was trying to address in this thread w.r.t. JSDL constraint models. It seems one could read Marvin's original question as being about resource discovery, but since he mentioned JSDL, I just assumed we were all talking about constraints in the job description. karl -- Karl Czajkowski karlcz@univa.com
