Descripción
Sumario:This paper describes in detail the infrastructure and installation of the CMS on-line computing centre (CMSOLC) and its associated monitoring system. In summer 2007, 640 PCs acting as detector Readout Units for the CMS Data Acquisition System (DAQ) were deployed along with ~150 servers for DAQ general services. Since summer 2008, ~900 PCs acting as DAQ Event Builder Units/Filter Units have been added and today, the CMSOLC has an on-line processing capability sufficient for a Level 1 trigger accept rate of 50 kHz. To ensure that these ~1700 PCs are running efficiently, a multi-level monitoring system has been put in place. This system is also described in this paper.
