Dear Marty Humphrey, NorduGrid would like to take part in this year's HPCP SC07 interoperability demonstrations (Nordugrid will have its own booth at SC07). During the GIN session at OGF21 we were informed that the HPCP group and you were coordinating this year's event. Unfortunately because of overlapping program we could not attend the "HPC Profile -- SC 2008 interopfest" session at OGF21. Would it be possible to read the notes if there are such (was this session really about SC08 and not SC07)? NorduGrid coordinates the development of the Advanced Resource Connector (ARC) middleware. As part of the recent ongoing development ARC acquired a new job management interface, the A-REX component which is a BES-compliant and JSDL capable job submission and management interface. As a first step we'd already listed NorduGrid's A-REX on the SC07 HPCP page as an implementation (http://forge.ogf.org/sf/go/projects.ogsa-hpcp-wg/wiki) and studied all the available material on the gridforge, joined the HPCP OGSA-WG (Gabor Roczei is our representative). Unfortunately, the information available on the "SC2007 HPC Profile Interop Fest Status" and the linked "HPC Basic Profile Compliance test" pages leaves many questions open. In particular, we'd like to know more about the followings: 1) how will the security be treated?, what will be used for authentication/authorization? 2) what sort of jobs will be submitted and by what kind of client(s)? Would be useful to be able to check out an example jsdl job request. Is the HPCBasicProfileComplianceTester page already functional? 3) What are the plans related to data stage in? 4) In general, what is the communication channel for the SC07 preparations, where can we post our questions? Is it the ogsa-hpcp-wg@ogf.org mailing list? best regards, Balazs Konya Technical Coordinator NorduGrid Collaboration ps: Marty, due to the approaching SC07 i decided to post my mail directly to the ogsa-hpcp-wg list as well. If this is the right discussion forum let's keep the discussion here.
