PGI additional co-chair election process
by Riedel, Morris 08 Jul '10

08 Jul '10

Dear PGI members, as Balazs recently stepped down as a co-chair we have now two positions vacant for these roles to support me in chairing the activities of the group. Although I'm still keen in supporting this group as co-chair, some new roles within JUELICH (e.g. becoming deputy division head) will have potentially an impact in the time I can invest in this group and thus we need urgently a backup for me - the sooner the better. The election of the new co-chairs is an open process and the group decides, but keep in mind that we have a tough time schedule and these positions should be filled as soon as possible to maintain progress. Hence, to support a faster election process, I already discussed group setups with members of OGF and PGI folks, I would therefore like to take the opportunity to recommend the group setup as follows: (1) I recommend that Johannes Watzl (LMU, Munich, Germany) would be one of the additional co-chairs. Johannes is active in GIN since years and participated in PGI since it's beginning as being an effective secretary. Furthermore, his technology-neutral position makes him even more a suitable candidate for chairing sessions/workshops with delicate decisions among the technology providers that contribute to PGI. I already discussed this with Johannes and he is willing to take this role once selected by the group. (2) The selection of Johannes would leave the secretary position as vacant. Given the past and current efforts of Etienne Urbah (LAL, Paris, France) via posters/e-mails/wiki-pages/etc., I would recommend that he should be elected for the secretary role. I already discussed with Etienne his contributions and he is keen to support the group as well in a more formal position. (3) One further additional co-chair position is still open. I'm in discussion with GIN/PGI members from outside of Europe to promote PGI as an international activity! Until these discussions will come to a fruitful state with folks that are willing to give the time required, I'm still open to receive recommendations from the community. Finally, please send me any serious objections (privately) to the proposed setup. If I do not receive significant objections until the end of next week (2010-07-02), I see this setup as being agreed by the group. Afterwards, I will be once again in contact with our area director Andrew Grimshaw to officially confirm the above recommended setup.

OGF PGI Execution Service : UML Sequence Diagrams for 3 different cases of Endpoint Stability
by Etienne URBAH 07 Jul '10

07 Jul '10

Morris, Johannes and all, Inside the requirements for OGF PGI Execution Service, there are 3 different cases of stability of Execution Service Endpoints, with corresponding consequences on the Activity ID. In order to ease understanding and discussion, I have created, for each of the 3 cases, a corresponding UML Sequence Diagram showing a possible sequence of operations : - JM4.4 (48) Single Endpoint JM4.7 (50) The Activity ID may be completely opaque http://forge.gridforum.org/sf/go/doc16006?nav=1 (PNG) - JM4.5 (49) Factory and Management Endpoints JM4.8 (51) From the Activity ID, the Client must be able to extract the URL of of the Management Endpoint http://forge.gridforum.org/sf/go/doc16007?nav=1 (PNG) - JM4.6 (168) Transient Endpoints - Each Execution Service must store the Activity ID inside a Name Server JM4.9 (52) The Client must be able to query the Name Server with the Activity Name in order to get the current Activity ID http://forge.gridforum.org/sf/go/doc16008?nav=1 (PNG) The source file is 'PGI Execution Service : UML file (ArgoUML)' at http://forge.gridforum.org/sf/go/doc15878?nav=1 I hope that these 3 UML Sequence Diagrams will be useful. Best regards. ----------------------------------------------------- Etienne URBAH LAL, Univ Paris-Sud, IN2P3/CNRS Bat 200 91898 ORSAY France Tel: +33 1 64 46 84 87 Skype: etienne.urbah Mob: +33 6 22 30 53 27 mailto:urbah@lal.in2p3.fr -----------------------------------------------------

We've "uploaded" our use cases to Morris (unfortunately, it turns out that we don't have write access to the PGI gridforge site so there not publicly available yet). -Mark

meeting notes from OGF29?
by Balazs Konya 01 Jul '10

01 Jul '10

Hi PGI, I heard from the nordugrid people that many things had happened during the productive OGF29 sessions. I was wondering if meeting notes containing decisions are available somewhere? Or the decisions are implicitly contained in the google document? bye, Balazs

Probably No PGI Telcon Today
by Morris Riedel 01 Jul '10

01 Jul '10

Dear PGI team, I'm in an important meeting the whole day and unfortunately can't chair a telcon today. I leave it to Johannes to organize a telcon if he finds time for it. Potentially some use cases and questions can be discussed. If there is no telcon, we should continue to provide the use cases as agreed last week in Chicago.
