OGF PGI F2F Meeting April in Amsterdam : Paperboard with color markers - GLUE poster
by urbah＠lal.in2p3.fr 25 Apr '10

25 Apr '10

Morris, Balazs, Luigi and Johannes, For the OGF PGI F2F Meeting in Amsterdam on 28-29 April 2010 : I suggest, besides the video-conferencing facility for participants who can NOT fly, to use a paperboard with markers of different colors : This is very useful, for example to : - Keep the discussion on focus by writing short descriptions of the current - Context, - Scope, - Subject of discussion within context and scope. - Draw a sketch or diagram clearly showing components, interfaces, boundaries, relationships, messages, persistence, ... At the end of the meeting, Johannes can detach the useful papers from the paper board in order to keep them, make good photos and publish them on GridForge. If a paperboard is not available, a whiteboard with erasable color markers would still be useful (in this case, someone should bring a camera in order to take a photo each time the whiteboard has to be wiped). For everyone understanding of GLUE, I also suggest to present a poster of the lower part 'Computing Entities - Relationships' extracted from Figure 2 'Entities and relationships for the Computing Service conceptual model' in page 22 of the 'GLUE Specification v. 2.0' at http://www.ogf.org/documents/GFD.147.pdf. Thank you in advance. 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 -----------------------------------------------------

Re: [Pgi-wg] Condensed Requirements List Version 2 in Grid Forge + Wiki
by Etienne URBAH 23 Apr '10

Morris, Balazs, Luigi, Johannes and all, Concerning the 'Requirements Wiki' containing Requirements tables at http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/Require… : - I have updated the MAIN Requirements Wiki page according to both telephone conferences of today. So, following sections are now up to date : - IS Information functionality - AA Security (Authentication, Authorization, Delegation) - AR Application Repository - Ac Accounting - LB Logging and Bookkeeping - JM Activity Management - JD Job Description - The DETAIL pages are up to date only for following sections : - IS Information functionality - AA Security (Authentication, Authorization, Delegation) - AR Application Repository - Ac Accounting - LB Logging and Bookkeeping - JM Activity Management (only until JM4.3) I am continuing to update the DETAIL pages, which are the adequate place to add your own explanations, questions, remarks, suggestions and opinions. - Besides, I have re-proposed following requirements with improved title : - IS2 Each Service MUST publish its properties (Name, Type, Endpoints, ...) and the properties of its Endpoints in conformance with GLUE recommendations - IS8 For not yet finished Activities, the Information functionality MUST accept requests querying the Activity Status, and MUST return this Status with different levels of verbosity (basic, detailed, more detailed) - IS9 For already finished Activities, the Information functionality SHOULD accept requests querying the Activity Status, but MAY return an error - IS13 For requests querying Activity Status, the Information functionality SHOULD support query languages - Ac1 The global Accounting functionality consolidates Accounting data at the grid level, securely keeps accounting data as persistent, implements complex accounting queries, and support the corresponding CPU load. Therefore, those Accounting sub-functionalities MUST NOT be implemented by the Execution Service (which has performance requirements for Activity Management), but by a completely separate Accounting Service. 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 ----------------------------------------------------- On Fri, 23/04/2010 17:08, Morris Riedel wrote: > Hi team, > > you can find the next iteration of the condensed requirements list > (version 2) in Grid Forge (over 4 MB): > > http://forge.gridforum.org/sf/docman/do/downloadDocument/projects.pgi-wg/doc > man.root.drafts.condensed_requirement_lists/doc15964 > > > We still have some requirements not touched yet. > > > Unfortunately we only can continue to work on them on Tuesday, but we feel > that many of the important ones (i.e. job management and job description) > are included in this version. > > > Your co-chair, > Morris > > ------------------------------------------------------------ > Morris Riedel > Distributed Systems and Grid Computing Division > > Jülich Supercomputing Centre (JSC) > Info: http://www.fz-juelich.de/jsc/JSCPeople/riedel

Hi team, you can find the next iteration of the condensed requirements list (version 2) in Grid Forge (over 4 MB): http://forge.gridforum.org/sf/docman/do/downloadDocument/projects.pgi-wg/doc man.root.drafts.condensed_requirement_lists/doc15964 We still have some requirements not touched yet. Unfortunately we only can continue to work on them on Tuesday, but we feel that many of the important ones (i.e. job management and job description) are included in this version.

Meeting in Amsterdam next week
by Andrew Grimshaw 22 Apr '10

22 Apr '10

All, After much internal discussion we have decided not to send Mark to Amsterdam next week. With the ash cloud situation, the uncertainties of travel are too high, with the exception that we can be sure it will be a mess. We remain committed to the process though. We will therefore, attend electronically - starting at 9 am Central European. Besides a phone in, is there a particular video conferencing setup? Is there equipment we should buy? Or will we be using a screen share such as glance? And regular dial in? Andrew

FW: [Csfaculty] More than you could ever want to know about volcanic ash and aircraft engines
