OGF Active Groups

Compute


Area Director: Ramin Yahyapour

The Compute Area is focused on the description and execution of computational tasks, and the scheduling and negotiation of grid resources.
 
 
Grid Resource Allocation Agreement Protocol WG (GRAAP-WG)
Group Information
Group Type: Working Group
Group Chair(s): Jim Pruyne, Wolfgang Ziegler
Group Secretary(s): Philipp Wieder
 
Group Description
The goal of the GRAAP Working Group is to produce a set of specifications and supporting documents which describe methods and means to establish Service Level Agreements between different entities in a distributed environment. The WS-Agreement Specification V1.0, a Web Services protocol to establish agreements between two services, has been published May 2007 as an OGF Proposed Recommendation: Just recently an errata version has been published fixin a few typos in the non-normative part. The new version supercedes the version of 2007 (see GFD.192). Along with this document the group has published the specification for extended negotiation and renegotiation on top of WS-Agreement as WS-Agreement Negotiation (see GFD.193).
 
Group Focus and Scope
Within the scope of the GRAAP-WG are the definition, the negotiation, and the management of Service Level Agreements (SLAs). The group especially focuses on the usage of SLAs and WS-Agreement, an SLA format and protocol specified by the GRAAP-WG, in distributed systems, Grids and Clouds. In the context of OGF, the relation to the Open Grid Services Architecture (OGSA) is of special importance.

The group is now working on a RESTful implementation of WS-Agreement.

Community request: In case you have implemented WS-Agreement, we would appreciate if you could invest the time and fill in this questionnaire. Also, if you plan to implement WS-Agreement Negotiation please let us know. Thank you.

Please find more information regarding the following topics on the respective pages of the GRAAP Wiki:
* Events related to WS-Agreement, GRAAP, and SLAs
* Existing implementations using WS-Agreement
* A discussion on interoperability between different WS-Agreement implementations
* A list of publications related to WS-Agreement and SLAs
* A discussion on SLA re-negotiation

Grid Scheduling Architecture RG (GSA-RG)
Group Information
Group Type: Research Group
Group Secretary(s): Ariel Oleksiak
 
Group Description
The goal of the Grid Scheduling Architecture Research Group (GSA-RG) is to define a scheduling architecture that supports cooperation between different scheduling instances for arbitrary Grid resources. The group currently focuses on the interoperation of different schedulers in an OGF-complaint ecosystem.
 
Group Focus and Scope
The definition of the scheduling architecture should support all kind of resources include network, software, data, storage and processing units. The research group will particularly address the interaction between resource management and data management. Co-allocation and the reservation of resources are key aspects of the new scheduling architecture, which will also include the integration of user or provider defined scheduling policies.

The group began with identifying a set of relevant approaches obtained in existing Grid projects resulting in GFD.64.

Currently, the GSA-RG reviews necessary protocols and interfaces to support interoperability between different Grid schedulers, and components of a modular scheduling architecture and their interactions. Services and protocols from other OGF groups are considered as potential basic building blocks of such an architecture and will be used wherever possible.

High Performance Computing Profile WG (HPCP-WG)
Group Information
Group Type: Working Group
 
Group Description
The objective of this working group is to work on the profile and specifications needed to realize the vertical use case of batch job scheduling of scientific/technical applications. This use case is often referred to as the "core" high performance computing (HPC) use case.

Job Submission Description Language WG (JSDL-WG)
Group Information
Group Type: Working Group
Group Secretary(s): Philipp Wieder
 
Group Description
The JSDL-WG has produced a language that describes the requirements of jobs for submission to Grids. JSDL 1.0 (published as GGF recommendation GFD-R-P.056 [http://www.ggf.org/documents/GFD.56.pdf]) is an XML-based language that focuses mainly on computational jobs. The JSDL-WG is working on extending this language to address a wider class of jobs.
 
Group Focus and Scope
Following the publication of JSDL 1.0[GFD.56] the group is working on improving and extending the language. An errata release of JSDL 1.0 is close to completion with clarifications for issues raised by the Grid community or identified through interoperability work. The group is
collaborating on a joint interoperability and experience report with BES-WG and HPCP-WG.

The group is also working on extending JSDL 1.0, for example, to allow more flexible resource requirements. Initially extending JSDL 1.0 such work is expected to lead eventually to a redesign and the next major version of the language.

OGSA Basic Execution Services WG (OGSA-BES-WG)
Group Information
Group Type: Working Group
 
Group Description
The objective of the OGSA-BES working group is to focus on a minimal sub-set of the EMS services and develop a recommendations document (i.e., specification) for them.

OGSA Resource Selection Services WG (OGSA-RSS-WG)
Group Information
Group Type: Working Group
Group Secretary(s): Ramin Yahyapour
 
Group Description
The OGSA-RSS-WG defines protocols for the scheduling functionality within the OGSA framework.
 
Group Focus and Scope
The OGSA-RSS WG will provide protocols and interface definitions for the Selection Services portion of the Execution Management Services (EMS) part of the Open Grid Services Architecture (see section 3.4.6, page 22 of GFD.30: “The Open Grid Services Architecture, Version 1.0”). The Resource Selection Services (RSS) consist of the Candidate Set Generator (CSG) and the Execution Planning System (EPS). The CSG can be used to generate a set of computational resources that are able to run a job in general, while the EPS uses this list to decide where to run the job. Other resources such as data are out of scope of these services.
