Two new OGF documents: GFD-E.103 and GFD-E.104 via DRMAA-WG
by Greg Newby 08 May '07

08 May '07

GFD-E.103: Condor DRMAA 1.0 Implementation -- Experience Report. P. Troger & B. Gietzel via DRMAA-WG. Abstract: This document describes experiences in the implementation of the Distributed Resource Management Application API (DRMAA) specification for the Condor workload management system. The document reports about issues that where identified during implementation and test of a DRMAA C library for Condor, which was evaluated successfully with the DRMAA working group compliance test for C bindings. We will give suggestions for improvement of the specification, mainly concerning readability of the GFD-R-P.022 specification document. GFD-E.104: GridWay DRMAA 1.0 Implementation -- Experience Report. J. Herrera et al., via DRMAA-WG. Abstract: This document reports about experiences made with running DRMAA working group compliance test for C bindings against GridWay 5.2 implementation of the Distributed Resource Management Application API (DRMAA). GridWay (www.gridway.org) is an open source meta-scheduling technology that, on top of Globus services, performs job execution management and resource brokering. 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. This document also includes some implementation details of the DRMAA API, and remarks some special considerations made to implement the DRMAA standard on a Grid (Globus based). The main difficulties arise because the nature of the Grid itself, as opposed to a classical Distributed Resource Management System (DRMS), which provides a single system image where all resources are in the same administration domain. For those who are wondering: there are some gaps in the document series numbering, due to numbers being pre-assigned for documents forthcoming soon. Also, there is a third DRMAA-WG document that will be announced shortly. Read these documents here: http://www.ogf.org/gf/docs/?final -- Greg Newby, OGF Editor

New OGF document: GFD-E.102: Interoperability Testing for The GridRPC API Specification
by Greg Newby 08 May '07

08 May '07

GFD-E.102: Interoperability Testing for The GridRPC API Specification. Y. Tanimura et al., via GridRPC-WG. Abstract: This document proposes a process of interoperability testing of the GridRPC API specification (GFD-R.52), which is submitted to the Global Grid Forum (GGF) recommendation track. Three independent implementations from different code bases, Ninf-G, GridSolve and DIET, are used for showing sufficient successful operational experiences. A strong belief that the specification is mature and will be useful is indicated through all the results of the test suites.

New OGF document: GFD-R-P.101: Resource Namespace Service Specification
by Greg Newby 08 May '07

08 May '07

GFD-R-P.101: Resource Namespace Service Specification. M. Pereira et al., via GFS-WG. Abstract: This document describes the specification of the Resource Namespace Service (RNS), which offers a simple standard way of mapping names to endpoints within a grid or distributed network. It functions as a Web Services registry that provides name-to-resource mapping. Names are mapped to endpoint references and are stored in a persistent namespace repository. RNS offers hierarchical rendering of human-oriented names, which makes resource mappings easily accessible and usable by human interface applications. It can be employed to manage the namespace of federated and virtualized data, services, or effectively any resource capable of being referenced in a grid/web environment. This document proposes a set of operations describing the port type, functions, and features of the Resource Namespace Service.

New OGF document: GFD-I.100: HPC Job Scheduling: Base Case and Common Cases
by Greg Newby 08 May '07

08 May '07

GFD-I.100: HPC Job Scheduling: Base Case and Common Cases. M. Theimer et al., via OGSA HPC Profile WG. Abstract: This document describes the set of use cases for batch job scheduling of scientific/technical applications, also broadly referred to as the core high performance computing (HPC) use case. A simple base case is defined that we expect to have universally implemented by all batch job scheduling clients and schedulers. Additional "Common Cases" are enumerated, which are anticipated to be applicable to at least two but not all batch job scheduling clients and schedulers. This Base Case and Common Cases will be used as a set of requirements for the forthcoming OGF proposed recommendation entitled "OGSATM HPC Profile". This document is a product of the OGSA HPC Profile WG of the Open Grid Forum. Read this document here: http://www.ogf.org/gf/docs/?final -- Greg Newby, OGF Editor

New OGF document: GFD-I.092: Use-Cases and Requirements for Grid Checkpoint and Recovery
by Greg Newby 08 May '07

08 May '07

GFD-I.092: Use-Cases and Requirements for Grid Checkpoint and Recovery. R. Badia et al., via GridCPR-WG. Abstract: This document describes use-cases to be addressed by the Grid Checkpoint and Recovery Working Group (GridCPR WG). The scenarios are also used to determine a set of requirements for these standards. Read this document here: http://www.ogf.org/gf/docs/?final Several more published documents to follow. As OGF's Editor, I'm happy to make you aware of these documents, which represent significant accomplishments for the groups involved. The GFSG believes it is in the OGF community's membership to be aware of new documents as they are published. You are getting this message to wg-all because you are on one of the many OGF mailing lists. The wg-all list is is a metalist. -- Greg Newby, OGF Editor
