by Morris Riedel 27 Apr '10

27 Apr '10

Hi team, here some pieces of information about the telcon and screen-sharing tools for Amsterdam: (1) TelCon System using HiDef (Attention: New Number! Not the old PGI one) Free of charge when calling from Skype: +9900827045746500 International Numbers: United States +1 (201) 793-9022 Canada +1 (201) 793-9022 Austria +43 (0) 82040115470 Belgium +32 (0) 7 0357134 France +33 (0) 826109071 Germany +49 01805009527 Ireland +353 (0) 818270968 Italy +39 848390177 Spain +34 (9) 02885791 Switzerland +41 (0) 8 48560397 United Kingdom +44 (0) 8454018081 Room number: 5746500 The majority if participants in PGI felt in the past that this system is the best system to use. No costs from Skype and nothing to install on the computer. (2) Screen-Sharing http://webconf.vc.dfn.de/ogf-pgi-wg/ No login is required. Just enter as 'guest' with your real world name. (3) We might use a video-conferencing facility that is available in Amsterdam but this needs to be checked tomorrow morning. Details on this will be send out when we decided that it makes sense to use it after local investigation.

Condensed Requirments List Version 3 in Grid Forge (ready for Amsterdam)
by Morris Riedel 27 Apr '10

27 Apr '10

Hi team, you can find the currently condensed requirements list (version 3) in Grid Forge (~ 6 MB): http://forge.gridforum.org/sf/docman/do/downloadDocument/projects.pgi-wg/doc man.root.drafts.condensed_requirement_lists/doc15968 An excel-export version of it can be found at: http://forge.gridforum.org/sf/docman/do/downloadDocument/projects.pgi-wg/doc man.root.drafts.condensed_requirement_lists/doc15969 Balazs, Etienne and myself spent the morning to finalize the list having the wiki as input. All requirements that have been re-proposed in the meanwhile will be discussed after the aforementioned list in Amsterdam in the next two days. @All: Please go through the wiki and the list and check whether we dropped requirements that you find substantial for PGI and re-propose them via e-mail.

OGF PGI : Requirements Wiki - Re-proposed and brand new requirements - Requirements needing clarification
by Etienne URBAH 26 Apr '10

26 Apr '10

Balazs, Morris, Luigi, Johannes and all, Inside the 'Requirements Wiki' containing Requirements tables at http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/Require… : As of now, re-proposed and brand new requirements requirements are : - 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 - IS14 In order to prevent overloading the Execution Service (which has performance requirements for Activity Management), the Information functionality SHOULD be separated from the Execution Service - Ac0 In order to permit efficient Accounting, a grid infrastructure MUST provide an Accounting functionality (without real time requirements) which consolidates Accounting records at the grid level from various systems, securely keeps Accounting records even after Activities have finished, implements complex accounting queries, and supports the corresponding CPU load - Ac1 In order to prevent overloading the Execution Service (which has performance requirements for Activity Management), the Accounting functionality MUST be separated from the Execution Service - JM6.11 For all requests concerning Activities, the Execution Service functionality MUST accept, as input parameter, 1 Activity ID - JM11 The Execution Service MAY provide its functionalities to Clients through various protocols (RPC, Corba, ActiveMQ, ...), but MUST provide them to Clients through a Web Service As of now, requirements needing clarification are : - NF8 Clean specifications and interface definitions, don't keep obsolete and never used elements (by whom?) - NF15 Need to support high availability and reliability - NF16 Single global namespace for resources of all kind (storage devices, compute device), ... - NF17 Easier usage to get more users involved. How does it effects PGI?! A general rule like global namespaces (for example: path) - NF18 Potential re-use of PGI portTypes by other services (for example: information portType) 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 -----------------------------------------------------

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

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
