Now that BES has been revised it's time to start defining an HPC Profile
by Marvin Theimer 04 Aug '06

04 Aug '06

Hi; Up till now the focus of HPC Profile work has effectively been to engage with the BES and JSDL working groups to try to effect changes that would be useful to the HPC Profile specification effort. As a consequence the email traffic and discussions have taken place on the BES and JSDL mailing list and teleconference calls. At the July face-to-face meeting in Argonne we made a lot of progress towards redefining BES in a manner that would nicely support an HPC Profile specification. We also discussed what kinds of restrictions would be appropriate to JSDL for the HPC Profile as well as the possibility of creating a "basic HPC execution" extension profile that could be used instead of the Posix extension in order to support non-Posix (e.g. Windows) execution systems. Given all this, it's now time to start working on a concrete HPC Profile specification. That means that you'll start seeing traffic on the HPC Profile mailing list (ogsa-hpcp-wg) and that we will start holding weekly telecon calls to make forward progress. I'm sending this email to several mailing lists in order to alert everyone to the fact that the ogsa-hpcp-wg mailing list is going to start seeing traffic and will become the locus of the discussion for the HPC Profile work. So if you're interested in participating - or just lurking and watching - please do start monitoring (and contributing to) the ogsa-hpcp-wg mailing list. One of the first things I'll be doing on the mailing list is nailing down a date and time for a recurring telecon call. Also, we've created a place on gridforge for HPC Profile-related documents: https://forge.gridforum.org/projects/ogsa-hpcp-wg/ That's where we will be putting all the documents related to the HPC Profile, including straw-man proposals. Indeed, if you have a straw-man proposal that you'd like to submit concerning any or all aspects of the HPC Profile then please feel free to post your document(s) to gridforge and alert people to them via email to the mailing list. Thanks, Marvin.

'+' marks added text.] - Ellen to send an email to Chris Jordan with the information needed to add these two documents to the OGSA Roadmap + Information sent. Done. - Hiro schedule a joint call with OGSA-Data to explain the Information model work before GGF18. - This could be one agenda item on the joing EMS/Data call already being schedule. + Joint call between EMS/DATA & Info Model is scheduled for August 17. Done. AI-0803a: Hiro to look into an option for a second EMS/Data call on Sep 7. Tentative; needs confirmation with likely participants. - Jun to feed back proposals 1a and 1b to the CDDLM Working Group, i.e. pass back the minutes to the WG. Ask Michel in case of any questions related to these proposals. + Discussed during this call. Closed - BES-WG chairs to ask the data group to define the filesystems as their work product + Hiro sent actions to WG chairs. Confirm that this is so and close. + Put on the agenda of the joint EMS/Data call. * July 2006 F2F minutes approval ** 20060718-pm-2 (GFS) - approved with no changes ** 20060719pm-2 (Joint Mgmt Committee) - approved with no changes. - Confirmed that there are no concrete actions on OGSA-WG at this time. ** 20060720-am-1 (Joint CDDLM) - approved with changes - Change XPath to XQuery - Modily statement on "removing environment variables from CDDLM" to removing from Posix component. (Proposal 2 correctly states this.) AI-0803b: Michel to revise and upload Joint CDDLM minutes (Done) ** 20060720-am-2 (EMS Scenarios) - approved with no changes ** 20060720-am-3 (G.Fox comments) - approved with no changes ** Roadmap minutes are not available (postponed) * GGF18 update ** B2B F2F GGF18 is probably finishing at 1pm on Thursday. Agreed to try and start the interim meeting from Thursday afternoon since many people are likely to want to leave early on Friday. Tentative start time: 2:30pm on Thursday AI-0803c: Ellen to book the IBM facility on Thursday afternoon AI-0803d: Hiro to divide GGF18 B2B F2F survey into three periods: Thursday afternoon, Friday morning and afternoon. ** GGF18 sessions - BES clashes with EMS session. Asked Joel to try and resolve it by moving one to a different slot. There are many dependencies, however. * Joint CDDLM discussion Discussed proposals from the F2F minutes (reproduced below and marked with '>') > PROPOSAL 1a: Use XPath 2.0 as an interface between the CDL document > and the CDL components - Clarified that this should be XQuery not XPath. - Agreed that it would be nice to do but it is probably a feature for the next version of CDL. It is one topic to discuss at GG18 as part of the future direction of the CDDLM-WG (See also AI-0803b) > PROPOSAL 1b: Use xsd:ID/xsd:IDREF to allow relations between elements in > CDL documents - Jun thinks that this is not a good idea because ID must be unique in the document and CDL inheritance may break this guarantee by creating duplicate IDs in the resulting document. CDL has a mechanism based on non-unique ids. AI-0803e: Jun will provide an example of the CDL mechanism and why using ID/IDREF is not a good idea. > * Proposals 1a and 1b are recommendations for the further > development of CDDLM Restated that both these proposals are for post-version 1.0 of CDL. > > PROPOSAL 2: Eliminate the EnvironmentVariable concept from the > PosixComponent (CDL plugin) > > * Proposal 2 is specific to the OGSA EMS scenarios document. Agreed that this is a reasonable resolution for resolving the problem with the PosixComponent and is sufficient for the EMS Scenarios document. AI-0803f: Jun will update the CDL document to remove the Environment variables (See also AI-0803b) - A normative definition of PosixComponent - At the moment there is no such definition; there are only some examples. - Agreed that a normative definition is necessary and that it is not part of CDL version 1.0. Also it is probably too late to leave it for CDL version 2.0---since it is not scheduled yet. - Tentative agreement that this should be a work item for CDDLM-WG between these two document release - Dejan and Jun with discuss this in the CDDLM-WG and seek approval as a work item after CDL 1.0.

Resignation
by Manuel Pereira 03 Aug '06

03 Aug '06

Dear Colleagues, It is with genuine sincerity that I express my gratitude for the many kind and gracious friends that I have had the opportunity to work with over the course of the past several years. I have thoroughly enjoyed participating in GGF as well as the creativity, friendly atmosphere, and stimulating activities availed by IBM. I am writing to you to inform you that I am resigning from IBM and the technical/scientific industry, including GGF and my leadership involvement. Though seemingly abrupt, this decision has been under consideration for over a year. The sole reason for my departure is in response to an inexplicable and ever increasing draw and loving desire to serve in full-time Christian ministry. I am pursuing higher education and training in one of the finest seminaries available while serving as a pastor of a regional Bible church. I leave IBM and all of my related participating activities in excellent standing and repute. I would love to share more with you, however out of respect for the diverse community of GGF, I want to invite anyone who is interested in more details or would simply like to discuss the matter to please contact me at: manuel(a)trinitybiblechurch.org. Best regards, Manuel Pereira ------------------------------------------------------ IBM Almaden Research Center 1-408-927-1935 [Tieline: 457] mpereira(a)us.ibm.com ------------------------------------------------------
