 The main scientific project PIC is associated to, in terms of utilization of computing resources, is the deployment, operations and maintenance of the Spanish Tier 1 site for the WLCG, supporting the ATLAS, CMS and LHCb experiments of the LHC at CERN.PIC researchers and computing experts hence contribute to the development of Grid Computing technologies, as required by the computing needs of these experiments.Other projects in which PIC researchers are involved include computing support for Astrophysics and Cosmology experiments (such as MAGIC, PAU and DES) and computing techniques for medical imaging.
