The former Spanish Ministry of Science and Innovation founded the RES in July 2006 as a response to the need of the Spanish scientific community for increased computation capacity and access to intensive calculation resources, considering the supercomputing resources as a decisive asset for the scientific and technological development of the country. The RES consists of a distributed virtual infrastructure of supercomputers located in different sites, each of which contributes to the total processing power available to users of different R&D groups. Currently, the supercomputers are located in Madrid (Supercomputing and Visualization Centre of Madrid), the Canary Islands (Astrophysical Institute of the Canary Islands and the Technological Institute of the Canary Islands), the Universities of Cantabria, Malaga, Valencia, and Zaragoza, CESGA, and CSUC, with the coordinating body being the Barcelona Supercomputing Center (BSC-CNS). The RES not only provides supercomputing resources, it also offers service of technical support to users as well as specific training. Moreover it organizes users’ meetings and scientific seminars. The goal of these actions is to improve the efficient usage of the resources and expand the use of supercomputing to all the research areas.
The CSUC is a public consortium that has been provided ICT infrastructure services for over 22 years. Sharing academic, scientific, library, knowledge transfer and management services, its goal is to achieve better efficacy and efficiency by boosting synergies and economies of scale. CSUC is formed by ten Catalan Universities and the Regional Government of Catalonia. Originally founded as the Supercomputing Centre of Catalonia in 1991, with the purpose of providing computing services, it currently provides services to over 200 institutions (universities, research institutions, hospitals, technology centres, scientific parks, etc.) with numerous research projects in areas such as physics, theoretical chemistry, biomolecular modeling, Earth sciences, numerical methods in engineering, etc. The CSUC has three supercomputers with different architectures and numerous specialized software to meet the wide variety of users’ needs, not only providing them easy access to supercomputers but also technical and scientific highly specialized support through a comprehensive supercomputing service. The infrastructure includes two clusters and a shared memory supercomputer, a SGI Altix UV1000 with 1,344 cores, 112 TB of disk and 6 TB of memory which allow simulations with a high memory demand. CSUC provides 20% of its computing capacity to the RES.
