Open Grid Forum

Events & Forums

Community Practice

Industry Standards

Bring communities together to

share, innovate, workshop and

outreach

Leverage expertise & experience of the

community to enable successful

building and operating of grids

Align with/influence other SDOs and/or

develop specifications that

lead to interoperable software standards

Application Area

Standards Areas Each group has an email list (

saga-wg@ogf.org

) and a GridForge

project

Simple API for Grid Applications (SAGA-WG)

Co-Chaired by:

Shantenu Jha , Thilo Kielmann , Tom Goodale

Note that SAGA-WG is one of many groups in

this Area

10© 2007 Open Grid Forum

Group Types

• Working Groups (WG)• Crisp focus on development of a specification or guideline• Clear milestones based on delivery of drafts and publication dates

• Research Groups (RG)• Focus can be broader than WG, but must be clear• Milestones based on delivery of drafts, organization of workshops, and workshop reports• Technology exploration (e.g., Semantic Grid-RG)

• Community Groups (CG)• Explore grid usage and requirements in a sector (e.g., Telco-CG)• Milestones based on delivery of requirements documents

• Full Listing:http://www.ogf.org/gf/group_info/areasgroups.php

11© 2007 Open Grid Forum

How Groups Work

• Because every group has a different charter and leadership, every group is different

• Consistent things:• Work is announced on the group email list• Deliverables are normally one or more documents• Documents follow the same publication process (OGF Editor)• “Rough consensus and working code” is the rule of thumb• All work done under OGF IPR Policy

• Inconsistent things:• Meeting cadence• Use of GridForge (web-based collaboration tool) for group work • Group deliverables differ based on chartered work

12© 2007 Open Grid Forum

OGF Editor

• Manages the publication process (GFD-C.1) and “pipeline”

• Ensures documents are consistently formatted

• Works with Area Directors/VPs to ensure technical viability of documents

• Drafts submitted to the “editor pipeline” • Editor project in GridForge• http://forge.ogf.org/sf/projects/ggf-editor

13© 2007 Open Grid Forum

Deliverables

• Different Groups have different deliverables• Research groups may hold workshops and create proceedings

documents and/or “best practice” documents• Working groups will likely deliver specifications but may have

preliminary “informational” documents to lay the foundation• Community groups may hold workshops that capture

requirements which are documented and given to working groups

• Other groups may document a well-used process in the grid industry or in the OGF organization

• Different deliverables require different document types

14© 2007 Open Grid Forum

OGF Document Types

• Informational• Informs the community of an interesting and useful

Grid-related technology, architecture, framework, or concept

• Specifies requirements related to a particular vertical application

• Experimental• Informs the community of the results of Grid-related

experiments, implementations, operational experience, or to propose an experimental specification

15© 2007 Open Grid Forum

Document Types

• Community Practice• Inform and influence the community regarding an approach or

process that is considered to be widely accepted by consensus and practice in the Grid community or within the OGF organization

• Recommendations (2 stage)• Documents a particular technical specification or a particular set

of guidelines for the application of a technical specification. The recommendations documents are intended to guide interoperability and promote standard approaches.

Standards Development

• Short Version of the Process• A group of people interested in creating a standard hold a

BoF (optional).• Grid Forum Steering Committee Approves a WG• In an open forum, the WG writes the specification• GFSG Review• Public Review• Final approval and publication

• Complex Open Process, …• but things can move very fast when there is energy

available.

18© 2007 Open Grid Forum

Technical Strategy Overview

• Defines the overall OGF technical strategy for the development of standards

• Three-year timeframe from 2006 to 2010• Describes the output of the OGF standards working

groups as well as the requirements that drive them.• Technical Strategy Document

• Focus Areas• Goals• Alignment Process• Use Cases• Roadmap

19© 2007 Open Grid Forum

Broad and Narrow Grids

• The concept allows for clearer communication encompassing all aspects and points of view on Grids.

• A Broad Grid is any collection of services• A Narrow Grid is defined by both the

technologies used, as well as the application focus. Some examples:• OGSA compliant Enterprise compute cluster• Web 2.0 Sensor Net linked to Google maps

20© 2007 Open Grid Forum

Narrow Grids of Focus

• Collaboration Grids• Multiple institutions, secure, widely distributed, VOs• Collaborative agreements & commercial partnerships• Financial Model: Increase overall revenue

• Data Centre Grids• Centralized management of multiple platforms• Aggregation of enterprise resources and applications• Financial Model: Reduce Total Cost of Ownership (TCO)

• Cluster Grids• Networks of Workstations, Blades, etc.• Cycle scavenging, Homogeneous workload• Financial Model: Lower marginal costs

21© 2007 Open Grid Forum

Goals of the TSC

• Identify use-cases, patterns, and scenarios• Publish documents• Design and drive the standards process.• Identify and highlight core architectural

standards • Encourage software developers

• From open source community and the commercial • To develop and implement standards

• Hold regular alignment summits

Technical Strategy & Roadmap

“Moon Shot” Goal

The Open Grid Forum should commit all its availableresources to the goal that before this decade is out,

commercial and academic organizationswill build real operational grids using

Open Grid Forum defined components.

There is a Gap Analysis too

• The Maturity column indicates the rough State of the Art with respect to each capability.

• Categories:• Out of Scope for the OGF• Gap that OGF should be investigating• Area of Grid Research• Evolving area either in OGF or some other SDO• Capability with Mature specifications or solutions.

TS&R Document Status

• Like all OGF documents it is always accessible in Gridforge

• forge.gridforum.org/sf/projects/tsc

• Has been through its Public Comment period

• To be published in time for OGF21 in October 2007

31© 2007 Open Grid Forum

OGF & DMTF Alliance

• Intention of the alliance is to cross-leverage each organization’s domain strength• DMTF focus on distributed management

infrastructure and information/data modeling of resources

• OGF focus on the deployment, operation and access to resources in a Grid

32© 2007 Open Grid Forum

Alliance Benefits

• Collaboration on broadening CIM to encompass Grid concepts

• Leverage technical and marketing resources in both DMTF and OGF

• Coordinate development processes and priorities between DMTF and OGF to ensure DMTF modeling standards address Grid technology, and that OGF Grid services address management requirements

• Education about technologies and activities across the organizations, and participation in each others events

33© 2007 Open Grid Forum

Current Work Register

• Review / Comment (1Q2007)• DSP 0225: URI Format for Published XML Schema• DSP 0230: WS-CIM Mapping Specification

• Extrapolate from the OGSA-BES work and submit to DMTF a general container model (current work in progress)

• Identify the base set of grid resources that need to be advertised that applications can consume (via requirements) and update the CIM as needed including how best to map/leverage information models. (current work in progress)
