Hi; The virtual design effort around the HPC Profile initiative has created a use case document, has discussed extension mechanisms, and has received a straw man design proposal from Ian Foster and Dave Snelling. Chris Smith and I have put together a second straw man design proposal so that we have two different proposals to discuss at the HPC Profile BoF in Tokyo next week. That proposal is included as an attachment to this email. Whereas Ian and Dave's ESI design had as its primary focus a unification of the Globus and Unicore designs, the focus of Chris and my design proposal is an evolutionary design in which there is a base case and numerous optional extensions. Of course, it also represents our views on how we think the HPC profile should look. :-) The enclosed paper is intentionally an unfinished design since our goal is to engender discussion and obtain feedback from the grid community for the HPC Profile effort. So we invite comments and feedback, both in email to this mailing list and in person during the BoF next week in Tokyo. Thanks, Marvin (and Chris).
