Fwd (replogle@ggf.org): [gf-chairs] GGF15 Session Scheduling is open
by Andre Merzky 17 Aug '05

17 Aug '05

Hi all, at GGF15, we will face a new policy for session scheduling: 2 sessions are allowed per group, more sessions need a confirmation of the AD. Although I understand the constraints GGF office is facing for scheduling sessions, I think we should try to get three sessions as at last GGF. After all we are (supposed to be) working on 2 documents, and want to advance the strawman to the document process soon. Do you have opinions to that? Do people feel three sessions are too many? Not enough? Please also note that 45 min slots are available as well, although counting for a full session. What may also help is a headcount of people who will attend GGF15. Could you raise a virtual hand, please? I'll be there.

Enterprise Grid Alliance...
by Andre Merzky 16 Aug '05

16 Aug '05

Hi all, I got pointed to the Enterprise Grid Alliance, and found a document there which might be of interest to the group (or not). From the summary: "The Reference Model provides a specific context for describing requirements, standards, comparing technologies and implementing grid solutions. The model delivers a framework and set of customer-based requirements needed to accelerate enterprise grid adoption. Included in its three main components are: - A common lexicon of grid terms - A model that classifies the management and lifecycles of the components required for enterprise grids - A set of use cases that demonstrate the requirements for enterprise grid computing. Like all of the EGA's work, the Reference Model is vendor neutral, technology and implementation agnostic, and will be continuously updated as the grid marketplace evolves." http://www.gridalliance.org/en/WorkGroups/referencemodel_download.asp The use cases described in the document are specified on a different level than the SAGA use cases - anyway, its an interesting read.

Java-Implementation
by Andre Merzky 09 Aug '05

09 Aug '05

Hi all, the Vrije Universiteit Amsterdam and Luisiana State University are currently implementing the SAGA API in C++. Java is the second language we want to approach, but we are somewhat short of resources. However, we do have the Java-GAT where we can start from, which already has internal parts available which we can reuse for SAGA. Also, the single Java GAT developer, Rob van Nieuwpoort at VU, will start to work on SAGA, however, he won't be able to implement that single handedly. Is there anybody in the group who wants to join that Java effort? Thomasz & Gregor: I heard from both of you some interest in a Java implementation before. Have you some/any resources to start with that in the next weeks? Anybody else who would like to contribute? Do you know of people/groups not on this list who would like to contribute? The implementation is supposed to be open source obviously (GPL or BSD License). We will probably use the same CVS repository that we use for other SAGA work (use cases, strawman and the C implementation), with anon read access. Best regards, Andre. -- +-----------------------------------------------------------------+ | Andre Merzky | phon: +31 - 20 - 598 - 7759 | | Vrije Universiteit Amsterdam (VU) | fax : +31 - 20 - 598 - 7653 | | Dept. of Computer Science | mail: merzky(a)cs.vu.nl | | De Boelelaan 1083a | www: http://www.merzky.net | | 1081 HV Amsterdam, Netherlands | | +-----------------------------------------------------------------+

Fwd (schintke@zib.de): [Gat] Interesting view on software libraries
by Andre Merzky 05 Aug '05

05 Aug '05

Hi Saga, Florian Schintke found a interesting paper on component reuasability. I think its awesome, although its results are probably difficult to apply to real world. However, it takes the Entropy of component domains into account. Consider the entrpopy in Grid middleware, and you immediately agree with the paper results! :-)) Thanks Florian!

Short Strawman versions
by Andre Merzky 04 Aug '05

04 Aug '05

Hi, to disable the excuse 'too long' for not reading the strawman API spec, we created a short version of the spec. It does not contain use case relation, notes, examples, and the detailed deiscussion of the API objects and methods, but only - intro etc - rationale for each subsystem - SIDL for each subsystem You can find the short version as pdf and txt on the WIKI: http://wiki.cct.lsu.edu/saga/ check the last links for the v0.2 version of the doc on the front page. However, please check the complete doc on any questions before complaining on the list, in particular when in doubt about call semantics.

Call for Cookies!
by Andre Merzky 04 Aug '05

04 Aug '05

Hi, Stephen made the proposal to create a CookBook for the SAGA strawman and later API, to increase the understanding for what we actuallt do. I started that on the WIKI, at http://wiki.cct.lsu.edu/saga/space/CookBook It would be great if people could contribute cookies or ideas for such (just create a page and describe what you want to see). Ultimately, we will also publich pieces from the UseCases there...

Job States
by Andre Merzky 04 Aug '05

04 Aug '05

Hiho. SAGA Jobs have currently following states: - Unknown, - HoldSystem, - HoldUser, - Hold, - Queued, - Running, - SuspendSystem, - SuspendUser, - Suspend, - DoneOk, - DoneFail I got the comment from colleques that PreStaging and PostStaging are missing. Indeed these stages seem not to fir into any of the above ones. Running would be a candidate, but since the remote resource is not neccessarily used anymore, that might be confusing. Should these stages be added? However, they do also not appear in the DRMAA specification AFAIK. Any thoughts? Another question: Assume I check a job status and find it 'DoneFail' - how can I determine the reason of failure? It would be useful to know the status the job was in before it failed (e.g. if it was prestating, I know then that staging failed, and the job never really started). Also it would be nice to be able to query for any error message. I think that the error query is distinct from the exception mechanism we will have: a job entering DoneFail should NOT throw an exception in my opinion - but that leads to above question: how can I query the error leading ot the DoneFail state? BTW: We should also check/sync with the error reporting mechanism for Tasks. Cheers, Andre. -- +-----------------------------------------------------------------+ | Andre Merzky | phon: +31 - 20 - 598 - 7759 | | Vrije Universiteit Amsterdam (VU) | fax : +31 - 20 - 598 - 7653 | | Dept. of Computer Science | mail: merzky(a)cs.vu.nl | | De Boelelaan 1083a | www: http://www.merzky.net | | 1081 HV Amsterdam, Netherlands | | +-----------------------------------------------------------------+
