In 2012, 14 Italian institutions participating in LHC Experiments won a grant from the Italian Ministry of Research (MIUR), with the aim of optimising analysis activities, and in general the Tier2/Tier3 infrastructure. We report on the activities being researched upon, on the considerable improvement in the ease of access to resources by physicists, also those with no specific computing interests. [...]

The Forbush decrease following the large X2 solar flare on mid-February 2011 has been observed by the muon telescopes of the EEE Project, which are located in several Italian sites and at CERN. Data from two different telescopes of the EEE network have been analyzed and compared to those measured by neutron monitor stations. [...]

(INFN, Bari ; Bari U.) ; Aiola, S (Catania U. ; INFN, Catania) ; Antolini, R (Gran Sasso) ; Avanzini, C (Pisa U. ; INFN, Pisa) ; Baldini Ferroli, R (Frascati ; Enrico Fermi Ctr., Rome) ; Bencivenni, G (Frascati) ; Bossini, E (Pisa U. ; INFN, Pisa) ; Bressan, E (Bologna U. ; INFN, Bologna ; Enrico Fermi Ctr., Rome) ; Chiavassa, A (Turin U. ; INFN, Turin) ; Cicalo, C (Cagliari U. ; INFN, Cagliari) et al.
The Gas Gain Monitoring (GGM) system of the Resistive Plate Chamber (RPC) muon detector in the Compact Muon Solenoid (CMS) experiment provides fast and accurate determination of the stability in the working point conditions due to gas mixture changes in the closed loop recirculation system. In 2011 the GGM began to operate using a feedback algorithm to control the applied voltage, in order to keep the GGM response insensitive to environmental temperature and atmospheric pressure variations.

Interoperating Cloud-based Virtual Farms

The present work aims at optimizing the use of computing resources available at the grid Italian Tier-2 sites of the ALICE experiment at CERN LHC by making them accessible to interactive distributed analysis, thanks to modern solutions based on cloud computing. The scalability and elasticity of the computing resources via dynamic (“on-demand”) provisioning is essentially limited by the size of the computing site, reaching the theoretical optimum only in the asymptotic case of infinite resources.
