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 Lusitania node is hosted in CénitS, the Extremadura Center for Research, Technological Innovation and Supercomputing. The aim of the center is to promote, disseminate and provide intensive calculation services and advanced communications to the Extremadura research communities, or to that company or institution that requests it, and in this way contribute through technological improvement and innovation to improve companies competitiveness. Lusitania supercomputer reaches a calculation capacity of 89.19 Teraflops.
