Executive SummaryThe GridCoord consortium held a workshop in Lisbon, on August 27-28th, 2005, called Grids@Large, which was co-localized with the Euro-Par 2005 conference. The aim was to bring together people with an experience in very large scale systems, and to explore how this experience could be reused in the Grid domains. Ten speakers were invited to demonstrate their knowledge in large scale deployment, and a panel was organized, to foster idea exchange (it was indeed animated and motivating). This spanned a wide spectrum: architecture, administration, networking, and Grid. The workshop was very successful, with an attendance of 35 people. Registration was made through the EuroPar registration page. All the expenses of the speakers were covered by the GridCoord project. The key findings of the workshop were:
The Grids@Large WorkshopWorkshop presentationIn the last couple of years, Grid has been following technical and scientific goals. Grids have grown to very large sizes, and the main issues have shifted to managing such big objects, and interacting with it. The international grid community has up to now developed environments based on “in-house” ideas and skills (Globus, Unicore, etc.), with little attention to sibling communities. The challenges set by really large scale use of grids will necessarily demand importing ideas from other technologies, in the first place peer-to-peer approaches, and component-based software engineering. So a workshop has been held in August 2005, to focus on displaying experience of people doing “actual” deployment and management of structures at a very large-scale, in a versatile and/or hostile environment (very large federations of clusters, intranets of international companies, the internet at large, etc.). It gathered researchers from the Grid, peer-to-peer and the component-based programming research area (mainly from Europe). In a previous discussion, it was pointed out that the real problem was not processors; it is rather managing users and institutions. It could be added: making long-term projects out of short-term budget commitments. In this respect, Grids are not different from anything else, but since the seminal Foster and Kesselman's comparison with the power grid; people have somehow collectively dreamed that they could be different. The goal of the workshop was not to provide an extensive, technical review of projects, but rather to explain what made possible the miracle that such a complex technical, institutional, human and financial organization works in the long-term. The workshop was made up with the contribution of ten invited speakers (who had their trip and accommodation paid for) and attracted thirty-five attendants. This grid workshop tried to give an updated vision of large-scale deployment, user management, financial issues, and security. Talks were held on topics like grid achievements, large-scale grids in other domains (particle physics), physical maintenance, and networking. This workshop was the place to show how grids can be real-life experiences. It was also a place of exchange, as mainly fruitful discussions took place, including one with Rosa M. Badia, from the CoreGrid Co-ordination and Education work package. The event took place in Lisbon, on August 27-28th 2005, and was co-localized with Euro-Par 2005 (http://europar05.di.fct.unl.pt/)which). Euro-Par is a series of “international conferences dedicated to the promotion and advancement of all aspects of parallel computing”. Its objective is to be the primary choice for researchers for the presentation of new results in their specific areas. The infrastructure for the workshop (rooms, meals, overhead projector), rented by the Euro-Par organization, provided entire satisfaction; Prof. José Cunha’s support was very gratefully appreciated. The funds involved (speaker support, logistics, meals, etc.) were provided by the INRIA and UNSA partners of the GridCoord consortium. This Grids@Large: Very Large Scale Grids workshop had a twin event, named Grids@Work: The Use of Open Middleware for the Grids, which was a week of events held in October in Sophia-Antipolis, France, between the 10th and the 14th. The week concentrated on proving how Grid is now a working reality, and seeing the different current possibilities, but also the shortcomings. A GridCoord Deliverable, called D.4.2.1, has also been written, “Specific workshop for Grid Researchers: Grids@Work”. The workshop homepage has been kept online (http://www-sop.inria.fr/workshop/gridatlarge/), and all the presentations remain accessible. The invited speakers The organizers invited all the speakers of the workshop. They were selected for their involvement in large-scale projects, and their influence on the administrative gears of their structure. They came from a wide spectrum of “large scale” fields like architecture, networking, programming, etc.
Workshop agenda The workshop was held on one and a half days. The first day grouped six talks, and was ended by a panel. The second day held the four last talks, and ended at 1pm.
