about expressing requirements on resources in JSDL using XQuery
by Sergio Andreozzi 26 Oct '10

26 Oct '10

Hi Morris, this document contains examples for the idea of using XQuery to express requirement on an XML-based resource description (in this case this is GLUE 2.0) http://ogf.org/documents/GFD.137.pdf The advantage of this approach is that JSDL is not bound to a set of terms and does not need to be changed according to the evolution of the information model. Cheers, Sergio -- Sergio Andreozzi - Policy Development Manager EGI.eu - Amsterdam - The Netherlands - http://egi.eu

OGF PGI - Requirements for Job Description
by Etienne URBAH 19 Oct '10

19 Oct '10

Morris, Johannes and all, Concerning the OGF PGI requirements for Job Description : From the EDGI use case 'Marshal Activities from Service Grid to Desktop Grid', the most important requirements, sorted by decreasing priority, are : JD3 (100) The Job Description document MUST reference all grid entities in conformance to the GLUE specification JD11 (107) Job Description should be only used for Job Description not for any kind of feedback. Job status information should not be communicated with a 'changed JSDL' JD4 (101) The Job Description document specification MUST permit the Client to request automatic data stage-in and stage-out JD22 (116) Clearly separate file and directory in the data-stagings. e.g. within the job description the element should be clearly labeled as file or directory, e.g. different aspect of handling directory or a file The other requirements labeled 'yes' are welcome, EXCEPT the 2 following ones, which generate too much COMPLEXITY in the Execution Service : JD6 (103) The Job Description document specification MUST permit the Client to request that at specified Activity states, the Execution service sets the Activity on 'Hold' [NO] JD8 (105) Job Description supports, 1) service-directed data-staging (i.e. specify data-stagings),2) client-initiated data-staging (i.e. specifiy data-staging but service will do nothing only control whether files existing), 3) manual data-staging (i.e. no specification of data-staging elements) [NO] 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 -----------------------------------------------------

Requirements mapping: Continued
by Oxana Smirnova 14 Oct '10

14 Oct '10

Hi again, here are the rest of requirements mapped to ARC, EGI and GROMACS use cases: ARC ----- Info: 1, 4, 6 Security: 9, 28, 29, 30, 32, 11 NF: 145, 146, 148, 149, 150, 156, 160 EGI ---- Accounting: 36 Info: 1, 4, 6 Security: 9, 17, 20, 21, 22, 23, 28, 29, 30, 32, 11 NF: 145, 146, 147, 148, 149, 150, 156, 160 GROMACS ------------- Info:1, 4, 6 SecurityL 28, 29, 11 NF: 148, 149, 156 I have to note that I did not prioritize requirements, because they can not be compared: there is no way to argue that e.g. a requirement of traceability is more or less important than that of using SOAP. I also should say that I noticed no duplicates, at least no obvious ones. And, the level of requirements varies really a lot, from extremely generic to extremely specific, which again prevents comparison. Cheers, Oxana

Re: [Pgi-wg] PGI Use Case Document: FINAL CALL for Group Comments
by Etienne URBAH 07 Oct '10

07 Oct '10

Morris, Johannes and all, I am not certain that the SourceForge Engine has sent following information to any other PGI member than myself, so I am sending it directly : I have submitted following review on the PGI Use Case Document, with 'PGI-Use-Cases-Review-Etienne.doc' available at http://forge.gridforum.org/sf/sfmain/do/downloadAttachment/projects.pgi-wg/… : Congratulation to Morris and Johannes for having achieved to collect these Use Cases on Distributed Data Processing (Grids). Concerning the Use Cases presented by EDGI (chapters 5, 6 and 7), I have directly : - added, inside 'Use Case Situation Analysis', the list of relevant official or de facto standards. - made cosmetic formatting changes. For the other chapters, I have inserted comments were needed. The most important ones are : - What are the software skills of users : Developers of the application which they use; Advanced users of the application; Users of a scientific grid portal or a workflow engine to launch something they do NOT know at all, but which should give them back useful scientific results; … ? - Please provide the detailed sequence of interactions between the users and the Grid infrastructure. Preconditions, triggers and postconditions are also useful. - Which parts of the scheduling are performed by the user, and which parts are performed by the Grid middleware (matching user requirements with resource capabilities) ? - Please provide precise description of resources which are the boundaries of the Grid infrastructure(s), and whose interfaces are used by the Use Case. - Is this really a requirement on Grid middleware, or rather a requirement on the Workflow engine ? I have also updated the properties of the MS-Word document. To view the submitted review, visit http://forge.ogf.org/sf/go/docr1214 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 Mon, 04/10/2010 23:42, Morris Riedel wrote: > Dear PGI team, > > the latest-greatest use case document (13 use cases, 43 pages) can be found in GridForge: > http://forge.gridforum.org/sf/docman/do/downloadDocument/projects.pgi-wg/do… > > If you have final comments please let me have them by Wednesday, > 2010-10-06 (end of the day). > > We already have given group members a long time to comment on the > use cases via our review process, telcons or via the mailing list, > so I don't expect any major changes. > > If any comments are minor (e.g. typos, formatting, minor wordsmithing) > I'll incorporate them and submit the document to the OGF editor on > Thursday morning. > > If I receive more serious comments I'll discuss with Johannes to > schedule time in our telcon this week, at which we'll agree either > to address them before publication or to create trackers/todo's and > defer them to a next version of the use case document. > > > Finally, I would like to thank the members of the PGI working group > for their great work in contributing with their use cases. > > > Your co-chair, > Morris > > ------------------------------------------------------------ > Morris Riedel > Deputy Division Leader > Distributed Systems and Grid Computing Division > > Jülich Supercomputing Centre (JSC) > Info: http://www.fz-juelich.de/jsc/JSCPeople/riedel
