JSDL Working Group Telecons
by Mark Morgan 03 Jan '11

03 Jan '11

Folks, As of today, I think all of the necessary e-paper work has been done to include me as one of the JSDL WG CoChairs. As a member of the PGI working group, and also as a supporter of JSDL technologies, I know that there are a lot of things that people would like to address in JSDL. To that end, I would like to start having regularly scheduled telecons for the JSDL WG again starting in the new year (starting the week of 10 Jan 2011 to 14 Jan 2011). I haven't figured out the telecon mechanism yet, but will before the first telecon. I've created a Doodle Poll to try and zero in on an acceptable telecon time. If you are interested in participating in JSDL, please go to the link http://www.doodle.com/xv6zv4re34p85xkq and indicate your availability for telecon participating. Voting for a time slot is an indication of your willingness to attend telecons when possible. You can assume that the existence of a time slot on the doodle pool constitutes a vote from me to attend at that time slot. I know that a lot of the times are kind of early for US folks, and probably a bit late for Japan, but hopefully they split the difference a bit. Also, I suggest we start out with a telecon every other week and increase the number as necessary once things get going. Thanks, Mark

OGF PGI : GLUE 2.0 attributes for usage inside JSDL - Requirement 100 (JD3)
by Etienne URBAH 17 Dec '10

17 Dec '10

Morris, Johannes and all, Concerning GLUE 2.0 attributes for usage inside JSDL : I have updated the draft document at http://forge.gridforum.org/sf/go/doc16171 This draft document now provides with more explanations : - JSDL leaf resource elements, - GLUE 2.0 'ComputingService' attributes, - GLUE 2.0 'ExecutionEnvironment' attributes. Please take at look at it, and do not hesitate to criticize it in order that we improve it. 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 Glossary of Acronyms and Terms - Erratum on the link

17 Dec '10

Morris, Johannes and all, The 'PGI Glossary of Acronyms and Terms' has now ended public comment period and is now referenced by SIENA as input document.

Using this 'OGF Editor Version' as basis, I have taken into account the public comments, and I have saved the result (with highlighted changes) as version 1.1 in http://forge.gridforum.org/sf/go/doc16036 for you to review. Do not hesitate to ask for further improvement.

PGI bylaws
by Oxana Smirnova 16 Dec '10

16 Dec '10

Hi all, please find attached the promised proposal for the PGI decision-making procedures (which looks just like a bylaw now). It is longer than half a page, but it's basically a formatting matter. If it is formatted without bullets (like the "Quorum" section), it gets shorter. Preamble can be removed as well, if we are into saving ink and paper. Cheers, Oxana

OGF PGI : Using GLUE 2.0 inside JSDL
by Etienne URBAH 09 Dec '10

09 Dec '10

Morris, Johannes and all, Concerning the usage of GLUE 2.0 inside JSDL : +------------------------+ | List of requirements | +------------------------+ I propose following list, which is extracted from chapter 4 of the 'PGI chart of priorities for the detailed specification of PGI requirements' at http://forge.gridforum.org/sf/go/doc16156 : For JSDL (apart SPMD, MPI and Application profile) -------------------------------------------------- 100 : http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/ReqJD3 The Job Description document MUST reference all grid entities in conformance to the GLUE specification 112 : http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/ReqJD17 Job Description document should offer a clear separation between resource requirements and application requirements (for example: suggest to put memory information into resource), e.g. improving the JSDL specification in this context (if necessary) 115 : http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/ReqJD20 It must be possible to specify hardware characteristics (e.g. in terms of a benchmark value) corresponding to the indicated performance numbers For JSDL SPMD and MPI --------------------- 108 : http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/ReqJD13 Job Description comes with support for requesting multi-processor Activities (for example: threads/node, network topology, task/core mappings, multi-threading and such like). For JSDL Application Profile ---------------------------- 34 : http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/ReqAR1 An easy way of launching applications or pre-configured /pre-installed software w/o specifying location details. Installed/pre-configured ones should be exposed as well as part of the resource description. The available software should be exposed through the service and in turn be requestable for resource/applications statements in JSDL. E.g. extending the JSDL with "pre-configured sw pieces" and/or "software libraries", e.g. global namespace of this applications might be beneficial as well. , etc. 35 : http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/ReqAR2 Application management, for example: pre-installed applications, abstract notion of the application (i.e. specify w/o executable locations) 113 : http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/ReqJD18 Job Description document should offer a new re-usable structure to describe an executable composed as folder and filename +------------------------------------+ | Detailed work on requirement 100 | +------------------------------------+ 100 : http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/ReqJD3 The Job Description document MUST reference all grid entities in conformance to the GLUE specification Rationale --------- Figure 1 of the 'Job Submission Description Language (JSDL) Specification, Version 1.0' at http://www.ogf.org/documents/GFD.136.pdf] clearly shows that, in order to work correctly, a 'Superscheduler, or Broker, or …' has to match client requirements expressed in the JSDL document to information provided by a Grid Information System. Therefore, it is essential that client requirements on entities described by GLUE use only GLUE classes and attributes. For XML purposes, I propose to use the 'glue' namespace specified at http://schemas.ggf.org/glue/2008/05/spec_2.0_d42_r01 JSDL elements clearly incompatible with GLUE 2.0 ------------------------------------------------ Searching for JSDL elements clearly incompatible with GLUE 2.0 at http://www.ogf.org/documents/GFD.147.pdf I have found following ones (but careful study by other persons could perhaps find other ones) : - JSDL 'ProcessorArchitectureEnumeration' specified in JSDL section 5.2.1 and used by the 'CPUArchitectureName' element specified in JSDL section 6.4.15 : The corresponding GLUE 2.0 enumeration is 'Platform_t' specified in GLUE 2.0 appendix B.26. While some JSDL values (such as 'powerpc' and 'sparc') match GLUE 2.0 values, some other JSDL values (such as 'x86_64', 'x86_32' and 'ia64') do NOT match GLUE 2.0 values (which are respectively 'amd64', 'i386' and 'itanium'). Therefore, I propose to deprecate JSDL 'ProcessorArchitectureEnumeration' and replace it with GLUE 2.0 'Platform_t' enumeration (for XML, inside the above described 'glue' namespace). - JSDL 'OperatingSystemTypeEnumeration' specified in JSDL section 5.2.3 and used by the 'OperatingSystemName' element specified in JSDL section 6.4.12 :\\ The corresponding GLUE 2.0 enumerations are 'OSFamily_t' specified in GLUE 2.0 appendix B.23 and 'OSName_t' specified in GLUE 2.0 appendix B.24.\\ GLUE 2.0 permits the client to specify the desired OS either through a vague requirement ('OSFamily' attribute) or through a precise requirement ('OSName' attribute).\\ Therefore, I propose to deprecate JSDL 'OperatingSystemTypeEnumeration' and replace it with the GLUE 2.0 'OSFamily_t' and 'OSName_t' enumerations (for XML, inside the above described 'glue' namespace). Practical usage of the 2 previous proposals permitting backward compatibility should be easily achieved using the JSDL 'other' value as described in JSDL section 4.3 'Semantics of the JSDL “other” Value'. Please study and criticize the above proposals. Do not hesitate to add comments and suggestions for improvements at http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/ReqJD3 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 -----------------------------------------------------
