Reduction on investment is making scientist to become more and more efficient on the use of resources and international cooperation will become a key target. These major aims are clearly reflected on the activity of IBERGRID. The usage of the resources of the IBERGRID NGI has increased in a 18% from last year reaching almost 180 million KSI2K hours from July 2012 until June 2013. The Large Hadron Collider (LHC) experiments continue representing the major share of these usage, but multidisciplinary Virtual Organizations keep the same share as previous years, being IBERGRID one of top NGIs in EGI dedicating a major share to non-LHC scientists. On the other side, the usage of the EGI infrastructure by Spanish users have increased up to 161 million KSI2K hours from July 2012 until June 2013, 20% more than in the same period of the previous year. The participation of Spanish institutions in European projects in Research Infrastructures has increased up to 12 European projects, some of them showing their result on this book. This year’s edition specially addresses cloud computing and expertise from user communities. Challenges such as the federation of virtual infrastructures and the easy deployment of services and virtual appliances constitute a major trend in today’s research. The Spanish participation in the EGI’s Virtualized Clouds Task Force has been important and relevant. Regarding the use cases, experiences in the LHC, energy, biodiversity, en- gineering and security will be presented and discussed, surely showing many common points for exchanging approaches and solutions. ICT advances in dis- tributed systems in terms of data, fault-tolerance and interoperability will also be presented. Finally, it is important to mention that IBERGIRD organizes the 2013 Tech- nical Forum of EGI in Madrid, Spain. This event will bring over 400 of par- ticipants with interest on distributed infrastructures for research, including top members of the European Commission. This seventh IBERGRID conference has been co-located with this major event. We believe that attendees to IBERGRID will strongly benefit from the wider scope of the technical forum while increasing the changes of impact to their presentations. IBERGRID is a mature and lively community that seamlessly work with a wide impact on the Spanish and Portuguese research communities. It constitutes a major example of bi-lateral cooperation and a solid partner for international cooperation.

Martins G. Borges, N. Dias, H. Gomes, J. Gomes, J. Pina, C. Manuel Laborat´oriode Instrumenta¸c˜ao e F´ısica Experimental de Part´ıculas, Portugal [email protected], [email protected] Abstract. SPARKS is a new flexible and modular solution to optimize the execution of computing tasks with the minimum of available resources, focusing on power consumption reduction. SPARKS acts as a third party agent inter playing with the Local Resource Management System (LRMS) and the cluster resources. The agent tries to influence the resource al- location decisions with the objective to concentrate executing tasks in non-filled hosts, minimize the necessity to wake-up new resources, and power down unused hosts. The proposed approach provides the necessary resources to the LRMS without really interfering on any of its scheduling decisions guaranteeing that the resource allocation policies are never in- fringed. 1 Introduction High Energy and Particle Physics research institutions are well known to host scientists performing state of the art research with extraordinary computing power requirements. Such researchers are normally part of wider worldwide col- laborations focused, at a technical level, on the processing of large amounts of experimental data collected at big

    Monday, Oct 12, 2009 Keynote Presentations Infrastructures Use, Requirements and Prospects in ICT for Health Domain Karin Johansson European Commission, Brussels, Belgium Progress in Integrating Networks with Service Oriented Architectures / Grids: ESnet's Guaranteed Bandwidth Service William E. Johnston Senior Scientist, Energy Sciences Network, Lawrence Berkeley National Laboratory, USA The past several years have seen Grid software mature to the point where it is now at the heart of some of the largest science data analysis systems - notably the CMS and Atlas experiments at the LHC. Systems like these, with their integrated, distributed data management and work flow management routinely treat computing and storage resources as 'services'. That is, resources that that can be discovered, queried as to present and future state, and that can be scheduled with guaranteed capacity. In Grid based systems the network provides the communication among these service-based resources, yet historically the network is a 'best effort' resource offering no guarantees and little state transparency. Recent work in the R&E network community, that is associated with the science community, has made progress toward developing network capabilities that provide service-like characteristics: Guaranteed capacity can be scheduled in advance and transparency for the state of the network from end-to-end. These services have grown out of initial work in the Global Grid Forum's Grid Performance Working Group. The services are defined by standard interfaces and data formats, but may have very different implementations in different networks. An ad hoc international working group has been implementing, testing, and refining these services in order to ensure interoperability among the many network domains involved in science collaborations.
