Welcome on CMS@MIB cluster Home page


These are the web pages for the computer cluster of CMS collaboration in Milano-Bicocca1, now registered as the GRID site INFN-MIB. The main goal of this project is offer a local computing resource to the CMS  Milano-Bicocca collaboration for analyses and data simulation. The cluster is composed of  several computing nodes (multiprocessor, multicore rack-mounted servers) connected together by a GigaBit Switch in a private network. All the computing nodes are members of a Fibre Channel Storage Area Network, connected by a Fibre Channel Switch to the storage system. All the nodes share the same disk space via GPFS2 file system. The storage system is composed by three FC-to-SATA RAID storage (~60 TB RAID0/5) with redundant power supply and controller. Failover and redundancy of the links to the storage are managed by  the multipath software. TORQUE/OpenPBS is the bach system. A  gateway server allows users to login and to run interactive jobs. Two cluster nodes are configured  as  GRID Storage Element (SE)  with STORM installed. Users of the cluster can  run GRID jobs and redirect the output on the SE. The are  also two dedicated file servers: one for the managment,  monitoring  and administration of the cluster; the other for the on-line  daily backup of the user area.
