Mid-range Computing Use case modified
by Mark Morgan 27 Sep '10

27 Sep '10

I have uploaded the "Mid-range Computing" usecase document with revisions to address comments. Summarized as follows: * Comments from Morris Riedel - Comments embedded in the original -- I tried to address these as they popped up in the document - PGI section could be filled in with more detailed "requirements" that are not covered by BES, JSDL, etc. -- I'm not really sure what you mean here. That section says that those specs cover what PGI needs, so there are no additional requirements not covered by them. I can't really list requirements not covered by BES and JSDL without knowing details of PGI that I don't have * Comments from Etienne - The template is BAD -- The template is the exact one that we as a group decided on (more than once) to adopt. Comment is therefor irrelevant and unhelpful. * Oxana - Does not address necessity of common interfaces and standards -- No part of the use case requires those things, why should the use case have them? - Too generic -- Possibly, however, changing it to be less generic would significantly change the use case itself making it a new use case and so I left it as it is. if it is unacceptable in its current state, then that is OK, but otherwise it is what it is.

High Capacity Use Case updated
by Mark Morgan 27 Sep '10

27 Sep '10

I have uploaded the "High Capacity Computing" usecase document with revisions to address comments. Summarized as follows: * Comments from Morris Riedel - Clarify difference between HTC and HPC -- Based off of your comments embedded in the document itself, I have added a small clarification statement in the introductory paragraph - Title is confusing -- clarify -- Wasn't entirely sure what to do with this, so I changed the title to get rid of the "Traditional HPC User" portion, hopefully disambiguating the title. * Comments from Etienne - The template is BAD -- The template is the exact one that we as a group decided on (more than once) to adopt. Comment is therefor irrelevant and unhelpful. * Oxana - Does not address necessity of common interfaces and standards -- No part of the use case requires those things, why should the use case have them? - Not sure how its different from the mid-range use case -- I believe that it is, but that is a subjective assertion and I am willing to accept that it isn't different. If it isn't, then we can as a group decide to pick one or the other - Implementation suggestions all over the place -- I can't agree with this comment. There are a number of places where implementations are given as examples, but they are not suggested as solutions -- I also describe some implementation details in the "How does it relate to PGI" which I agree shouldn't be in there, but we all agreed as a group to adopt that template, and the template asked for those items and so they are there. In my opinion, they are there because of the template, but not part of the use case in general.

Reminder: PGI Set of Requirements & Upcoming Specification Work
by Morris Riedel 24 Sep '10

24 Sep '10

Hi PGI team, I looked up the latest-greatest requirement table that is available in GridForge: http://forge.gridforum.org/sf/docman/do/downloadDocument/projects.pgi-wg/do… According to the prioritized use cases we can narrow them down to the urgent important ones in order to proceed with the specification work. We have done the long process of doing the glossary and use cases. Now it's time to finally create the specs while these documents are soon at the OGF editor. In this context we said that anybody can come up with a specification that take the requirements based on the prioritized use cases into account. Please make yourself familiar with the requirements again. This enables us to finally identify the urgent ones derived from the use cases and render them into specifications during October. The discussion about this process will start next week in our Telcon, but please prepare the telcon with getting yourself familiar again with initial collected requirements/use cases. Let's aim at a rough consensus-based specification at Supercomputing 2010 (mid-Nov). Take care, 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

PGI Glossary v.10: FINAL CALL for Group Comments
by Morris Riedel 22 Sep '10

22 Sep '10

Hi PGI team, the latest-greatest glossary version 10 can be found in GridForge: http://forge.gridforum.org/sf/docman/do/downloadDocument/projects.pgi-wg/do… Etienne incorporated the comments from the draft reviewers. If you have final comments please let me have them by Sunday, 2010-09-26 (end of the day). We already have given group members a long time to comment on the glossary within the 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 Monday morning. If I receive more serious comments I'll discuss with Johannes to schedule time for a final telcon discussion next 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 glossary. Finally, I would like to thank Etienne for its work on the document. Take care, 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

Genesis II Security - Trust Anchor(s)
by Etienne URBAH 22 Sep '10

22 Sep '10

Duane and Andrew, I have carefully read the document 'Genesis-II Security Implementation' at http://forge.gridforum.org/sf/go/doc15435?nav=1 Basic interoperation between different grid infrastructures require to establish mutual trust and common processes. Currently, Security Policies for EGI are proposed by EGI SPG 'Security Policy Group' at https://wiki.egi.eu/wiki/SPG In particular, 'Approval of Certification Authorities' at https://documents.egi.eu/public/ShowDocument?docid=83 defines that the Trust Anchor is IGTF http://www.igtf.net/ In order to permit basic interoperation between EGI and infrastructures using Genesis II, members of EGI SPG need to have precise information on Trust Anchor and Security Process used by grid infrastructures using Genesis II. Referring to your above mentioned 'Genesis-II Security Implementation' document : 1.1.2 Resource Identity ------------------------ - The document states 'All Genesis II grid resources are given X.509 identities' and the 4th entry of a 'typical certificate chain of trust' is a 'global Certificate Authority (CA) "trusted" by all grid participants'. - Please explain precisely this "trust" process : If this process does not use IGTF as unique Trust Anchor, please indicate the mandatory (and perhaps optional) Trust Anchor(s) for grid infrastructures using Genesis II. 1.1.4 Existing Identities -------------------------- - The document states 'Alternatively, users may have identities that are managed by directory systems such as NIS/YP, LDAP, etc. Genesis II integrates with these systems to virtualize these identities into the grid' - Does Genesis II really create X509 certificates (like an SLCS CA) ? - If yes, which Root CA does Genesis II use ? - Are you sure that this Root CA will be accepted by the target resources inside the grid infrastructures using Genesis II ? - If yes, what is the trust mechanism ? 1.1.6 Identity Provider Resources (IDPs) ----------------------------------------- - The document states 'New grid identities can be created and managed using Genesis II Identity Provider (IDP) resources' implementing 'WS-Trust Security Token Service (STS)' - Same questions as for section 1.1.4 Precise answers to these questions, taking into account real operational constraints, would permit EGI SPG to understand the security process offered by Genesis II, and perhaps to define a more flexible policy about Trust Anchors, permitting real interoperation with grid infrastructures using Genesis II. Thank you in advance for taking the pain of understanding these questions and answering to them. 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 -----------------------------------------------------

No PGI TelCon today
by Morris Riedel 16 Sep '10

16 Sep '10

Hi team, both chairs (Johannes and myself) are currently busy in the European event EGI Technical Forum. Therefore, there is no PGI Telcon today. Thanks so far for sending the final use cases to the list and please continue in case you didn't yet. Our aim is to have the document ready for OGF and we need another pass around the list before we submit it to the OGF editor. Take care, 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
