SCIENTIFIC COMPUTING FOR PARTICLE PHYSICS
The Scientific Computing Unit engages in the development and implementation of data-intensive distributed computing technologies, such as Grid and Cloud computing, and highly parallel processing techniques, providing infrastructure and support to the particle physics, astroparticle and observational cosmology projects of the department. In particular, the Unit operates two data centers of the Worldwide LHC Computing Grid (WLCG), a distributed computing infrastructure built to meet the challenge of data processing on an unprecedented scale in the LHC. A Tier-2 center for the CMS experiment is located in the CIEMAT site in Madrid and a Tier-1 center is managed in Barcelona at PIC. PIC has emerged as a reference center for scientific computing techniques in a enviroment of massive datasets that allows to support a wide range of scientific disciplines.
