Integration of GLUE 2 and OGSA-BES
by Sergio Andreozzi 09 Aug '07

09 Aug '07

Hi everybody, in the context of the OMII-Europe project, we are preparing to contribute an implementation of GLUE 2 to be integrated into OGSA-BES implementations (info providers will be available for the OMII-Europe partners, nevertheless the work can be leveraged for other platforms). The idea is to implement the GLUE 2 specification draft that will be available by OGF 21. The aim is to have a prototype implementation to be showed during SuperComputing 2007. Here is a draft document of the possible implementation approaches. You are invited to have a look and contribute for suggestions: http://omii-europe.forge.cnaf.infn.it/jra2/glue/bes-glue-integration Last notice, I will be on holiday for the coming two weeks, therefore we will resume this topic starting from 27 Aug. Cheers, Sergio -- Sergio Andreozzi INFN-CNAF, Tel: +39 051 609 2860 Viale Berti Pichat, 6/2 Fax: +39 051 609 2746 40126 Bologna (Italy) Web: http://www.cnaf.infn.it/~andreozzi

***SPAM*** Windows Workflow
by Steven Newhouse 07 Aug '07

07 Aug '07

AI-0614a: Steven Newhouse will check whether Windows Workflow can also be used with CCS / BES style services In under two days I was able to (from scratch) build some custom workflow activities to transfer files to/from a server over FTP and to use the HPCP web service to run a job on a cluster resource. This time also included gaining familiarity with the Visual Studio IDE, the Workflow builder components within that, oh and gaining familiarity with C#. From a developer perspective I'm obviously quite impressed! I did not really explore all of the different workflow activities that come provided (parallel, if/else, while, etc.) but the ones I did all seemed fairly straightforward to use. Its straightforward to give an activity properties and to specify these as customizations within a workflow. This allowed me to move a file from my workflow client to the HPC resource, to start a job on the resource, and to transfer back an output file. There are opportunities for simplifying this... e.g. parsing the JSDL file to extract out the transfer ins & outs. And to make the workflow more complex! There's a whole load of stuff on validation, hibernating/dehibernating running workflows, persistence, etc. that I did not explore. With a set of pre-defined configurable activities I see no reason why a technically competent person (not a programmer) could not use a preconfigured environment to build and run their own workflows. Steven PS: I am sure there are other equally excellent ways of doing this in other environments... my focus was on the Windows tooling.

Teleconference minutes - 26 July 2007 - Workflow
by Hiro Kishimoto 07 Aug '07

07 Aug '07

Hi all, Draft workflow minutes from 26 July 2007 attached. It is also uploaded onto the GridForge. - https://forge.gridforum.org/sf/go/doc14702 Thanks, -- Hiro Kishimoto --------------------------------------------- OGSA Teleconference - 26 July 2007 - Workflow ============================================= * Participants Michel Drescher (Fujitsu) Chris Kantarjiev (Oracle) Fabio Benedetti (IBM) Bahare Rahmanzadeh Donal Fellows (UMAN) Hiro Kishimoto (Fujitsu) Andreas Savva (Fujitsu) ZackK Minutes: Hiro Kishimoto * Agenda bashing Michel proposes the following as today's session; - Open discussion - Donal report out about Taverna - Discuss a schedule * June 14 minutes accepted * New action item AI-0726a: Show typical/existing use cases for cyclic dependency declarations (spawned from AI-0508a, owner unspecified) * Action items review AI-0508a: Donal to get in contact with Taverna Drill use cases for cyclic dependency declarations Donal has sent out overview of Taverna to the list and also will explain at today's session. AI closed. Since "cyclic dependency" is not covered, new AI specific to "cyclic dependency" is created but no one takes charge of it. AI-0726a (new): Show typical/existing use cases for cyclic dependency declarations (spawned from AI-0508a, owner unspecified) AI-0511b: Michel to pull workflow strawman proposal together No progress, keep it open. AI-0614a: Steven Newhouse will check whether Windows Workflow can also be used with CCS / BES style services No progress, keep it open. AI-0614b: Andreas will put the initial presentation points on the wiki Done. AI-0614c: Andreas will put the initial questionnaire points on the wiki Done. AI-0614d: Steve McGough will compile the list and put it on the wiki This is a list for presentations. Keep it open. We will clarify at the August F2F. AI-0614e: Steve McGough will look for the workflow material from the Berlin GGF Keep it open. * Taverna workflows by Donal Fellows Taverna is not service oriented workflow but data oriented workflow. It is actually data & control oriented workflow. Taverna is scientific oriented, underneath medical or pharmaceuticals resource managements are expected to be free to use. There is no run time authorization mechanism. However a workflow should go through ethics committee and it requires human intervention. How much work will be necessary to Tavarna people adopt standards? It should not be BPEL, Taverna is very very different from BPEL. BPEL workflow document is easy to becomes very large but Taverna is much sophisticate than BPEL. Taverna has very unique view for how to model. They don't depend specific execution environment but use specific meta date. * Next step Donal thinks it is remote chance to succeed workflow standard. No one wants to achieve workflow interoperability. Chris Kantarjiev says interoperability is out of our scope. Donal agrees. Control job dependency is in-scope. Donal thinks it is rather components dependency. Exapmle is just run posix jobs. Donal thinks Steve wants to stay simple cases. Hiro says we work on community practice document as fast track. Consensus is "focus community practice document" (fast track). Job dependency (2nd track) should be postponed and focus community practice document. * OGF21 session plan OGSA-WG will request 5 sessions including workflow. If it is not necessary, we can cancel it later. Chris K, our AD, is ok to submit 5 session request. Hiro will do so shortly.

Re: [ogsa-wg] [OGSA-D-WG] Definition of "data service"
by Subramaniam, Ravi 02 Aug '07

02 Aug '07

Hi, I would think that data is neither a resource, capability nor service. It is a unique entity/concept/essence. Thinking of data as a capability, resource or service can be problematic. Data is 'manipulated' by resources (could not think of a more appropriate word to represent the concept that I am thinking so I put it in quotes). To clarify data can be stored on a resource (storage), distributed by a resource (network), organised by or as a resource (file), operated on by a resource (CPU). Note: the items in parenthesis in the earlier sentence are resources (or more precisely resource types). A service provides access to or a view of a resource (i.e. a *portal* into one or a set of resources) - this latter part is congruent with the WSRF approach. By this thought process, a 'data service' or 'data resource' is a misnomer. A service is a portal into or the external manifestation of a resource which in turn 'operates' (in a wide sense) on data. Part of the confusion appears on where in this 'concept chain' we are. So if we are at the resource level we introduce terms like 'data resource' or at the service level 'data service'. In the example on files in the earlier part of the thread: The file is a resource used to organise data. The operations performed on a file is the service that is the external manifestations of the resource (i.e. the file) By this definition, we manage resources and not data. Actually data management is only achieved by managing the resources that 'operate' on data.

There is a separate question as to whether the data *is* a capability; I suspect it is, at least in some abstract sense. On the other hand, you might wish to distinguish the data as a special kind of capability that needs non-generic handling. So can you suggest the modification to the definition that will incorporate what you just above? "Donal K.

A data resource is an abstraction of a file, so I'd imagine that you'd want to describe it as a resource that is an ordered collection of organized information. (The idea is that it doesn't have to be in a file, but it does have many file-like characteristics.) It's strongly beneficial to the overall OGSA if you can have data resources being a subclass of resources (by referencing the OGSA glossary).
