WP4 cares of offering easy access to all kinds of users, of supporting all relevant services with the ultimate view  to establish a  self-sustainable e-Infratsruture.

On July 4, 2012 the CERN Director General announced the 1st observation of a particle consistent with the Higgs boson. The news transformed into a snowball being rolling all around the world in the TV and radio flashes thus generating a kind of "Higgsteria".

The GISELA Community was particularly excited by the information. Indeed several Latin American Institutions, members of GISELA, such as UFRJ (Brazil), UNAM (México), UniAndes (Colombia), etc. are using its e-Infrastructure, in the framework of the Computing model of the LHC experiments in which they participate. The picture below, shows the cumulative use of the GISELA e-Infrastructure by these institutions, for their various computing tasks such as simulation of physics processes, detector data processing and physics analysis. One should emphasize that Grid e-Infrastructures is a must for High Energy Physics experiments which could not otherwise deal with the sophisticated, CPU-consuming treatment of the data provided by their particle detectors. Hence it was really wonderful to observe, on a sensational case, the actual discovery power of Grid .


 The following figures show the GISELA e-Infrastructure contribution to the worldwide Grid usage, over Sep.2011 - Jun. 2012. All numbers  are given in wall time hours.
