Breaking News - Irving Wladawsky-Berger Keynote Added to OGF22 Program
Irving Wladawsky-Berger, Chairman Emeritus of the IBM Academy, will keynote Wednesday's program at 1:15 PM. He will present "Cloud Computing, Grids and the upcoming Cambrian Explosion in IT". Irving is well known for his early leadership of the internet, Linux and Grids and was an early contributor to GGF.

OGF Launches Thought Leadership Series
OGF recently launched its new thought leadership series to give thought leaders in OGF and the greater Grid and distributed computing community the opportunity to express their ideas, opinions and perspectives in an online public forum. One of the main goals of the series is to stimulate discussion and provoke lively debate on a broad range of hot topics and issues facing the grid and distributed computing community.

Wolfgang Gentzsch, Coordinator of the German D-Grid Initiative; Geoffrey Fox and Marlon Pierce, from the Community Grids Laboratory at Indiana University; and Ian Foster from Argonne National Lab and University of Chicago, have helped us kick-off the series with an interesting range of articles that provide a flavor of the diverse subject matter OGF hopes to address. Wolfgang's article outlines the "Top 10 Rules for Building a Sustainable Grid". Geoffrey and Marlon tackle the hard issues, "Too much Computing, Too much Data and Never too much Simplicity", facing the Grid community as emerging new computing resources and alternative approaches change the overall landscape. Ian Foster's article, "There's Grids in them thar Clouds" discusses whether or not "cloud computing" is just a new name for grid.

OGF welcomes everyone to comment and encourages all thought leaders in the Grid and distributed computing community to submit articles for this series. Submitting is easy to do, simply email it to thoughtleadership@ogf.org.

GLUE Q&A with Working Group Co-chair Sergio Andreozzi
GLUE is one of OGF's newer working groups, having formed in January 07. Over the past year, the team has been very active, working to facilitate interoperation between Grid infrastructures via enabling the development of interoperating Grid middleware components in response to existing use cases. GridConnections recently caught up with Sergio Andreozzi at the Management Developer's conference to get an update on their progress:

GridConnections: What is GLUE?

Sergio Andreozzi: GLUE is about information interoperability in the Grid context, a key building block to enable services to become aware of each other in terms of capabilities and functional states. Some of the questions that we try to answer are: how does a meta-scheduler discover available computing resources, execution environment characteristics, and protocols? How does a visualization tool build views of the available resources? How is information defined and structured to enable exchange among services?

The second generation of the GLUE Information Model is being designed in the context of OGF in order to leverage the existing solutions defined by various Grid projects and with the aim to unify them into a recommendation, thus adding one more piece to the puzzle of standard-based interoperability. This is important for many actors of Grid systems: middleware developers, so they have a clear definition of what is important to measure and expose; end-users, so they know the terms to use when specifying the requirements for their applications; and Virtual Organization managers and Grid operators, so they can compare the resources from different administrative domains.

GridConnections: What is the timescale for this specification and who do you expect will be the early adopters?

Sergio Andreozzi: By OGF22 (February 25-28, Cambridge, MA) we expect to have a mature proposal to be presented and, based on the feedback that we receive, we plan to publish it for public comment just afterwards. In the context of the OMII-Europe project, we are already implementing the specification and we are building a framework (codename GLUEMan) to manage information providers for GLUE 2.0 leveraging WBEM technologies. The early implementation is meant for early evaluation of both the information model and the various renderings that will be defined by the group (e.g., XML Schema, LDAP, SQL). Early adopters will be the projects participating in the GLUE 2.0 definition, among them EGEE, UNICORE, ARC, TERAGRID, D-Grid and AustralianGrid.

GridConnections: What lessons did you learn as you were developing this specification?

Sergio Andreozzi: First thing was that the Open Grid Forum is "really open". My perception had been that starting and co-chairing a working group in OGF would be a difficult and long process. The experience was instead totally different. The proposal was easily accepted and the GLUE WG became official in just a few weeks. Going to OGF also expanded the interest in this activity and now we have more projects supporting this work. During the first year of work I had also fruitful collaborations with other OGF working groups such as the Reference Model and the OGSA WGs. Of course there is a cost to pay for this. Producing a recommendation is a social process which requires more time than making everything on your own. But if we look at the history in other contexts, (e.g., telecommunications, WWW), we understand that this is the main path to realize the vision of what Grid should be and to open to a healthy competition among the various players.

I also learned that becoming an active participant in OGF eases interactions with other working groups and provides much more opportunity to exchange ideas and receive valuable suggestions.

GridConnections: What are your future plans for the recommendation?

Sergio Andreozzi: Our goal is to produce and present a mature specification at OGF22. This includes main entities (e.g.: administrative/user domains, service), computing entities (to model complex computing resources as clusters or supercomputers) and storage entities. The months following OGF22 will be dedicated to make it a proposed recommendation with available open source implementations that can be adopted by the Grid community.

Special Insert - OGF22 Session Previews
The leaders of the following sessions wish to invite all interested OGF22 attendees to come to their sessions to learn, participate and meet their fellow colleagues!

Cloud Systems BoF
Wednesday 2/27 at 2:00 PM in the Cambridge Room
There will be a Birds of a Feather session at OGF22 on "Cloud Systems" that aims to set scene and review options for OGF activities in this area. It follows a keynote by Irving Wladawsky-Berger of IBM on "Cloud Computing, Grids and the upcoming Cambrian Explosion in IT". Anyone interested in either presenting or participating in a panel at this BOF should contact gcf@indiana.edu so we can plan the session.

HPC Profile Working Group
Tuesday 2/26 at 11:15 AM in the Cambridge Room
The HPC Profile WG recently produced the "Interoperability Experiences with the High Performance Computing Basic Profile (HPCBP), Version 1.0", which is an OGF document currently in public comment. At OGF22, we will focus our efforts beyond this "Basic Profile" into two specific areas: a File Staging Extension (for moving files into and/or out of a HPC Basic Profile-compliant service) and the "Advanced Filter Extension" (for dynamically querying HPC Basic Profile-compliant services for information that might be relevant to the client). We encourage everyone to attend to contribute requirements, feedback, and general opinions to ensure success of the HPC Profile WG!

JSDL Working Group
Monday 2/25 at 11:15 AM in the William Dawes Room
The JSDL-WG has produced a language that describes the requirements of jobs (or activities) for submission to Grids. Work continues on improving and extending the language to a wider class of activities, including Web service invocations, parallel Job execution, and more complicated submission patterns such as parameter sweep submissions. The group is also resolving issues raised by the Grid community. At OGF22, the group will discuss ongoing work on defining parameter sweep jobs and new work on representing all information about an activity---not just its submission requirements---over the activity's entire lifetime.

GLUE Working Group
Wednesday 2/27 at 9:00 AM and 3:45 PM in the William Dawes Room
Thursday 2/28 at 10:45 AM in the Crispus Attucks Room
The GLUE Working Group is converging towards a stable version of the GLUE Information Model specification. During OGF 22, the status of the model and the reference implementations will be discussed. If you are interested in GLUE adoption, take the opportunity to participate in the session and get engaged in order to early adopt the upcoming standard and to provide feedback so that your specific scenarios are fully supported by the specification.

Remote Instrumentation Services in Grid Environment - use cases
Wednesday 2/27 at 9:00 AM in the Thomas Paine Room
The RISGE-RG main purpose is to integrate approaches in defining remote access interfaces to sophisticated laboratory equipment in e-Infrastructure environments. This concerns steering, monitoring and user access to unique instruments. The RISGE explore issues related to the usage of advanced Grid capabilities such as interactivity, visualisation in the process of monitoring as well as execution of measurement tasks and experiments on complex remote scientific equipment. This session is a continuation of the discussion and work started during first RISGE-RG group session at OGF21 in Seattle. During this session the group will discuss the first collected use cases and present best practices. If you are interested in remote instrumentation, interactivity, steering and visualisation in grids - don't miss that session.

GSM Working Group Sessions
Wednesday 2/27 at 9:00 AM, 10:45 AM, and 11:30 AM in the Molly Pitcher Room
Would it not be nice if every storage system could be accessed from the Grid? From a single disk server to multi-petabyte tape robots, a common interface to storage systems must deliver interoperation and flexibility. The Grid Storage Management working group (GSM-WG) is the standards group for the Storage Resource Manager (SRM) protocol which provides a common control interface to Grid storage elements. Across the Large Hadron Collider Computing Grid, about 200 storage elements run SRM version one and over 50 version two. With at least seven different interoperating implementations, the protocol is now a widely used and well established standard.

OMII-Europe: Using open standards to deliver interoperability
Monday 2/25 at 11:15 AM in the Molly Pitcher Room
OGF standards play a crucial role in the work done by the OMII-Europe project. This EU-funded project is tasked with delivering a set of interoperable components that can work across three Grid middleware platforms: gLite, Globus and UNICORE. OMII-Europe has have identified five key components and are re-engineering them using open standards. These components enable Grid users to overcome boundaries between Grid infrastructures and harness the power of more resources. This presentation will describe these components and how the OGF standards have helped achieve interoperability. Moreover, a real use case will be explored in which this software is not only beneficial, but necessary. This will be complemented by a live demo on Monday (25th) evening which will show how the combined use of the OMII-Europe components helps e-scientists.

DAIS Working Group
Wednesday 2/27 at 3:45 in the Thomas Paine Room
The DAIS WG is defining service-based access to data sources. It has already defined specifications for relational/XML resources. The group is now extending this framework for Resource Description Framework (RDF) based data, which is of importance with the proliferation of semantic web technologies. The proposed RDF specifications define two classes of access: one for managing RDF(S) data using ontology handling primitives; and another based on the SPARQL query language for RDF. At OGF22, we will report on progress on specifications, including a new Glossary of Terms and use cases which show the usage of Semantic Web technologies in the Grid.

OGSA Data Movement Interface (DMI) Working Group
Monday 2/25 at 1:45 PM in the Thomas Paine room
The OGSA Data Movement Interface (DMI) Working Group is very close to its final goal of producing a specification that provides a service orientated framework for initiating and managing the movement of data from a user specified source and sink. The service infrastructure will then manage the transfer which could be scheduled and pick a suitable protocol to do this with. By OGF22, we hope to have taken the spec to public comment so if you want to know more or want to comment on what has been produced then please come to the OGSA-DMI session.

Scaling DRMAA codes to the Grid: A Demonstration on EGEE, TeraGrid and OSG
Tuesday 2/26 at 3:30 PM in the Molly Pitcher Room
The session describes the DRMAA language bindings and the support for interoperability provided by the GridWay Metascheduler. GridWay DRMAA implementation allows applications intended for clusters to scale to grid environments. As use case, we will demonstrate a widely used Bioinformatics application, CD-HIT, running on the EGEE, TeraGrid and OSG Infrastructures.

Porting Applications with Globus GridWay
Wednesday 2/27 at 10:45 AM in the Cambridge Room
GridWay is a widely-used metascheduling technology that performs job execution management and resource brokering on heterogeneous and dynamic Globus Grids. The session provides an overview of the process of installing, configuring and using GridWay, focusing on the development of applications using the C and JAVA bindings of the DRMAA OGF recommendation, which assures its compatibility with other management systems that implements the standard, such as SGE, Condor, Torque

The Preservation Environments Research Group (PERG)
Tuesday 2/26 at 3:30 PM in the Thomas Paine Room
This session will explore the implications of the use of Rule-Oriented Data Systems for the enforcement of preservation policies. Multiple international efforts are investigating the enforcement and validation of Trustworthy Digital Repository Assessment criteria. The projects include the NARA/SDSC Transcontinental Persistent Archive Prototype, the EU SHAMAN project - Sustaining Heritage Access through Multivalent Archiving, and the EU CASPAR project - Cultural, Artistic and Scientific knowledge for Preservation, Access and Retrieval. We will discuss the choice of management policies that should be enforced by the preservation environment, and demonstrate how related policies can be implemented as rules within the iRODS data grid software.

OGF22 Program Updates
Charlie Catlett - What OGF Can Do for Enterprises (A View from the CIO Office)
Tuesday at 8:30 AM
OGF and its predecessors have evolved over the past several years in terms of both who are the customers and how many customer communities can be effectively served. Catlett will speak about the needs of three communities from a first-hand perspective: scientists and engineers using distributed infrastructure, multi-institutional grid service providers, and large campus (university or laboratory) service providers. These requirements, and most importantly their intersection, provide a rich set of areas for OGF to contribute to information technology today. The term "Grid" is rarely precisely defined among these communities, but the purpose of OGF - and its opportunities to impact information technology - transcends terminology. Even when it comes to OGF's middle name.
