Upcoming Events

Dear Readers:

OGF23 is one of the largest and most important grid and distributed computing events taking place this year. The program features an extensive set of activities for all those interested in learning about Grid and distributed computing technologies. During the week, participants can choose from numerous sessions, workshops, seminars, keynote presentations and tutorials being offered by OGF and our event partners OGF-Europe and BEinGrid.

That is why we ask all the session leaders to brief you on their plans for the event and have dedicated this edition of the GridConnections newsletter almost entirely to OGF23. Even if you are not planning to go to Barcelona, you will want to refer back to the program schedule after the event to view the session presentations. If you will be at OGF23, do not miss the Town Hall meeting on Monday where there will be a very important final read-out from the Board sub-committee exploring OGF's future direction and mission.

OGSA DMI Session
Monday, 2 June at 14:00 in Montjuic

The OGSA-DMI has just gone through its final public comment phase - this session will give a very brief overview of the specification, describe how public comments were resolved and go on to discuss renderings and implementations of the OGSA-DMI specification. A fun session for all to attend.

Exploring Cloud Computing
Monday, 2 June at 15:45 in Barcelona B

A mix of invited talks, panel and free ranging discussion. Let us debate:
1) What is and equally interestingly what isn't a cloud?
2) What is implication of Clouds for Enterprise Data Centers?
3) If TeraGrid evolves to PetaCloud, how would it look?
4) What are research issues for Clouds?
5) Can one (or who could) "trust" clouds. Can clouds be used across borders of countries with different government policies?
6) Will Cloud interoperability be important; if so at what interface(s) will it be provided?
7) What is the killer app for clouds?
8) What is pricing model for clouds. Are data, computing, persistent and pulse services, communication all cost effective?
9) Are software environments like Hadoop or Google Application Engine (GAE with a python base) general?
10) Which is more promising in near future. Infrastructure as a Service Iaas (as in Amazon) or Platform as a Service PaaS (as in GAE) or both
11) How does MPI work?
12) and last but hopefully not least where do Grids fit in?

Opportunity still exists for other speakers

Quality for Grid & Grid for Quality Workshop: Sharing Experiences and Perspectives of Grid and Open Source Communities
Monday, 2 June at 15:45 in Barcelona A

This workshop aims at creating the floor for specific discussions about the Quality Assurance initiatives from two different perspectives: Grid and Open Source. The Agenda involves international Grid and Open Source experts. A relevant focus will be given at surveying how Grid can help people in assuring the quality of their software and how the classical QA best practices could be useful in the Grid environment, usually open source based. Interested in contributing and in participating, please, contact manieri@eng.it or matteo.melideo@eng.it for confirmation of attendance and request for further info.

Data Grids Birds of a Feather
Monday, 2 June at 15:45 in Montjuic

Data Grid concepts, such as "shared collections" and "shared resources" are useful in creating "collaborative data management infrastructures" for global enterprises and large-scale science. They allow data and storage resources to be collaboratively shared across multiple organizations. The proposed group will discuss on standards and best practices for data grid solutions. Anyone interested in either presenting or participating in this session should contact arun@sdsc.edu.

Integrating Service and Desktop Grid Birds of a Feather
Monday, 2 June at 15:45 in Sarria

There are scientific communities whose applications require much more computing resources than existing service grids (SG) like EGEE can provide. The main objectives of our session are to support these new communities with the necessary extensions of the existing Grid infrastructures, with the adaptation of their applications to this enhanced Grid infrastructure and with the provision of standard APIs and Grid application development tools.

To support the specific needs of these scientific communities we will interconnect EGEE Grid with existing Desktop Grid (DG) systems. Both of them having advantages. SGs are flexible but expensive. DGs are more restricted but able to collect 1-2 orders of magnitude more CPUs than SGs. This interconnection will provide advanced capabilities to more researchers, capturing commonalities, fostering interoperability, promoting open standards and federating approaches across disciplines. A last objective is to extend the potential user communities to involve ordinary citizens, students and employees to apply Grid technology in their every day life. The project objectives are complementary with the objectives of EGEE and a strong partnership between EDGeS and EGEE is foreseen.

Grid Economics and Business Models
Tuesday, 3 June at 15:45 in Barcelona B

As on-demand pay-per-use access to resources and Grids are brought together, technologies such as Utility and Cloud Computing are offering opportunities for new ways of accessing resources and new business models. Alongside these new business models are the economic and technical issues of resource pricing, access, security and payment. This session aims to explore some of these issues. The session will consist of presentations, including results from research being carried out in these areas, followed by discussion.

Tuesday, 3 June at 15:45 in Montjuic

The goal of the RESERVOIR project is to advance the competitiveness of the EU economy by introducing a powerful ICT infrastructure for reliable and effective delivery of services as utilities, in a manner analogous to electricity and telephony. This infrastructure will support the setup and deployment of services on demand, at competitive costs, across disparate administrative domains, ensuring quality of service. RESERVOIR will lay a foundation for a service-based European online economy, where services will be transparently, scalable and flexibly provisioned and managed for the benefit of businesses and citizens.

The prime deliverable will be an architecture and a reference implementation of a service-oriented infrastructure (SOI), which - building on open standards and new technologies - will provide a dependable framework for delivering services as utilities. We will demonstrate how this infrastructure supports the deployment and management of complex service scenarios. We aim to achieve significant quantifiable improvements in service delivery productivity, quality, availability and cost.

Remote Instrumentation Services in Grid Environment - Demo (LEGO Mindstorm) and Presentations
Tuesday, 3 June at 15:45 in Sant Gervasi

Using Grid Techniques to Optimise Energy Efficiency
Wednesday, 4 June at 09:00 in Barcelona C

With rising energy prices and growing concern about global warming, the question of energy efficiency has become a major concern for the ICT industry. This workshop will explore how grid mechanisms and techniques can capture and implement policies to enable more efficient use of IT resources. We have speakers from industry, academia and OGF; there will also be plenty of discussion. Potential approaches might include the development of scheduling algorithms for energy-aware management of task allocation, improvement of techniques for modelling energy efficiency, standardised formats for monitoring of and accounting for energy consumption, and the specification of appropriate policy frameworks.

Grid: Tools, Middleware and Applications Workshop
Wednesday, 4 June at 14:00 in Barcelona C

The need to integrate databases (DB) and DB technology in a grid environment has been already recognized as a fundamental requirement for many applications coming from several scientific domains. In that sense, some tools and services have been developed to deal with such needs. This workshop is aimed at reviewing the state of the art of the related research activities. Developers are invited to present tools and services designed to virtualize databases and their access through a grid environment, while users communities will report about the usage of those services and further requirements. This workshop represent a good opportunity for developers and users from different fields to exchange their experiences and solutions

GIN Security Profile Session
Wednesday, 4 June at 14:00 in Montjuic

During the interoperation and interoperability work in GIN, Grid security (authorization, authentication) is always a major showstopper. While numerous OGF specifications have been defined (and even more actually exist outside of OGF), we found that production Grids adopt these new set of standards or profiles rather slow, which typically is due to the slow adoption in the middleware systems deployed on these infrastructures. This in turn limits the scope of many interoperable components within cross-Grid scenarios. Therefore, based on feedback from the GIN discussions at OGF21, several workshops, and on the lessons learned from numerous interoperation / interoperability demonstrations this session will discuss how a security profile within production Grids would look like. Topics discussed will include the limitations of proxies, technologies for authorization and authentication, and standards (i.e. profile) that lead to a mid-term convergence between rather new SAML-based technologies (e.g. used within OMII-Europe or Shibboleth Federations) and long-term established technologies deployed on production Grids (e.g. Attribute-Certificate-based VOMS).

Wednesday, 4 June at 15:45 in Montjuic

BES, HPC extensions to BES, JSDL and GLUE are complementary specifications that together enable a richer description, selection and execution of activities for computing resources. If you are involved in their implementations, join this session to start the discussion on how to profile the usage of these specifications in order to enable an interoperable job submission activity across different Grid middleware implementations.

GLUE Working Group
Wednesday, 4 June at 17:30 and Thursday, 5 June at 09:00 & 11:00 in Montjuic

The GLUE Working Group submitted for public comment two specifications related to the GLUE 2.0 conceptual model for Grid resources and its realizations in terms of the XML Schema, LDAP schema and SQL. Join our sessions to learn about the content of the two new documents and about the ongoing implementations. Your use cases and feedback will be a valuable contribution to the evolution towards the final specifications.

JSDL Working Group Session
Thursday, 5 June at 14:00 in Les Corts

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. At OGF23 the group will discuss ongoing work on defining parameter sweep jobs, and on representing all information about an activity---not just its submission requirements---over the activity's entire lifetime.

Mapping HASS - e-Research for Humanities, Arts and Social Science Community Session
Thursday, 5 June at 14:00 in Sant Gervasi
