All, As promised, I've dusted down the Usage Scenarios, put new GGF boilerplate text (IPR statement, etc.) in, and submitted the document to the GGF Editor for public review. It will be great to see this document finally published. The document can be found in DOC and PDF (Sorry for the usually long GridForge URLs): https://forge.gridforum.org/projects/graap-wg/document/draft-ggf- graap-usagescenarios-02.doc/en/1 https://forge.gridforum.org/projects/graap-wg/document/draft-ggf- graap-usagescenarios-02.pdf/en/1 The GGF Editor tracker for the document is at: https://forge.gridforum.org/tracker/?aid=1726 Cheers, Jon.

GSA-RG session at GGF 16
by Philipp Wieder 09 Feb '06

09 Feb '06

Dear All, the GSA-RG would like to invite you to our session at GGF 16. Date: Tuesday, February 14, 2006 Time: 3:30 pm - 5:00 pm Location: Olympia B We are especially looking forward to see three presentations on state-of-the-art scheduling systems. These presentations will examine generic Grid scheduling requirements and will therefore also be of interest to groups like GRAAP or OGSA-RSS. Please find the respective abstracts below. I hope to see you in Athens. Best regards, Philipp. ABSTRACTS: ---------- 1. "Workflow Scheduling in the ASKALON Grid Environment" by Marek Wieczorek, University of Innsbruck The ASKALON Grid environment is a full Grid environment designed to compose and execute scentific workflow applications. The ASKALON scheduler is a dynamic scheduling service using different optimization techniques to maximize the user's profit in accessing the Grid. Pluggable architecture of the scheduler enables the user to apply different workflow scheduling algorithms, to apply advance reservations, and to consider different optimization criteria, among them execution time and economic cost. Acting as a part of a full Grid environment, the scheduler interacts with other components of the ASKALON, namely with the resource management, the enactment engine, the performance prediction and the monitoring services, trying to make scheduling decisions based on the most reliable and up-to-date information. Our goals are to make the service SLA-aware and to extend it in the directions recommended by the GGF community. Besides the functionality of ASKALON scheduler we will also reflect general requirements for a Grid scheduler. 2. "The VIOLA Meta-scheduling Service" by Wolfgang Ziegler, Fraunhofer SCAI Distributed applications or workflows usually require different specialised resources like compute nodes, visualisation devices, storage devices, or network connectivity with a defined QoS at the same time or within a given period of time to be executed successfully. Orchestrating such resources on a local level within one organisation is only a minor organisational problem. Orchestration of resources on a Grid level requires a service that is able to solve the same problems in an environment that probably stretches across several administrative domains. Additional conditions have to be taken into account, like site autonomy and different site policies. In this talk we first describe the environment where co-allocation of resources is of vital importance, the requirements for the MetaScheduling service that provides the required co-allocation means, and related work. In the next step we characterise the functionality of the MetaScheduling service, followed by the description of the current implementation. As a use case we show the integration of the scheduling system into the UNICORE Grid middleware and finally we present a new project based on this work that started end of 2005. 3. "GridWay Scheduling Architecture" by Ignacio Martín Llorente, Universidad Complutense de Madrid GridWay, on top of Globus services, enables large-scale, secure and reliable sharing of computing resources (clusters, computing farms, servers, supercomputers...), managed by different resource management systems (PBS, SGE, LSF, Condor...), within a single organization (enterprise grid) or scattered across several administrative domains (partner or supply-chain grid). GridWay is an open source meta-scheduling technology that performs job execution management and resource brokering, allowing unattended, reliable, and efficient execution of jobs, array jobs, or complex jobs on heterogeneous and dynamic Grids. GridWay performs all the job scheduling and submission steps transparently to the end user and adapts job execution to changing Grid conditions by providing fault recovery mechanisms, dynamic scheduling, migration on-request and opportunistic migration. The presentation describes the scheduling requirements for partner grid computing, the functionality provided by GridWay to meet those requirements, the GridWay scheduling architecture and finally its requirements on core Grid services for the implementation of such functionality.

minutes from 2/8 telecon
by Jim Pruyne 08 Feb '06

08 Feb '06

They are attached. Next week is GGF, so there will be no conference call. We'll plan to have one the following week, on the 22nd, unless no one is ready to do so soon after GGF. Also, and updated version of the spec. from today's call will be uploaded to grid-forge in a moment. --- Jim Attendees --------- Toshi Nakata Jim Pruyne Anne Anderson Asit Dan Wolfgang Ziegler Discussion ---------- * GGF session discussion. No concerns all set for next week. Toshi will use first session to update state of public comments. * Spreadsheet id 7: changed resource to "service" * Spreadsheet id 10: Decided not to add WS-Name since we're not familiar with it, and there is a very broad array of values that might be used here. * Spreadsheet id 11: We're trying to standarize on the term service rather than resource. * Spreadsheet id 12: Made some changes to how we refer to SDTs in 4.2.2 and 4.2.3, but we need to look at all of the places where we're referring to terms in the text and the schema. We should have a consistent method of referring to these with or without spaces. Toshi will take a look through the document to see where else this needs to be addressed (e.g. in Guarantee Terms, etc.)

condition expression language requirements for WS-Agreement
by Anne Anderson 08 Feb '06

08 Feb '06

WS-Agreement is supposed to be "a Web Services protocol for establishing agreement between two parties". Unless there are defined mechanisms for reaching agreement on the contents of a WS-Agreement specification, I don't believe WS-Agreement has met its primary goal. Particularly in the area of condition expression languages, there has been little successful work on feasible intersection/agreement mechanisms other than the work done in the field of "narrowing algorithms". For example, there is intersection/agreement between two general XQuery expressions is undefined. There is a comment suggesting that the condition expression language/dialect be completely at the discretion of the WS-Agreement instance originator, which will make this problem even harder unless there is a corresponding requirement that two parties must either agree on the dialect used (and that it have a feasible intersection/agreement mechanism) or that there must be a defined intersection/agreement mechanism between the two dialects. I recommend inserting a requirement that any language/dialect specified for WS-Agreement condition expressions must have a referenceable specification for computing intersection or agreement between any two expressions in the language/dialect. Unless this is done, WS-Agreement will not meet its goals and will not be interoperable. Regards, Anne -- Anne H.
