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 Extremadura (Extremadura Center for Research, Technological Innovation and Supercomputing), the Canary Islands (Instituto Astrofísico de Canarias), Castilla y León (Castilla y León Supercomputing Center), the Universities of Cantabria, Autónoma de Madrid, Málaga, 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 CESGA is an institutionthat is jointly owned by the Regional Government of Galicia and the CSIC. The mission of the CESGA, established in 1993, is to contribute to the advancement of science and technology through the research and application of high-performance computing and communications, in partnership with other institutions and for the benefit of society. The CESGA hosts the Finis Terrae supercomputer since 2008, with 2400 processors and 14,01 Tflops/s, currently undergoing a process of renovation, expected to reach more than 300 Tflops/s during 2015. Finis Terrae is a constellation-type supercomputer formed from two subsystems – a computing system and a massive online storage system, both of which are essential for its correct operation. Supercomputers such as Finis Terrae can provide benefits to a very wide range of scientific areas. Additionally, CESGA has other cloud and grid type computing platforms and works in other areas of activity such as advanced communications, collaborative tools, transfer to industry, or GIS. Finis Terrae contributes to RES with 20% of its computing power.
