Linux-Cluster - LSA's ROCKS Based Linux Cluster
The LSA ROCKS based Linux cluster "linux-cluster" consists of a head node and 16 compute nodes with an Infiniband interconnect. The compute nodes have dual Opteron 250 2.4Ghz 64-bit processors with 4GB of RAM and 160GB hard drives. The head node also has dual Opteron 250 2.4Ghz 64-bit processors with 4GB of RAM and a 1TB SATA RAID. Job scheduling and management are done using Torque/Maui (PBS). In addition to the GNU compilers, the cluster also has PGI (Portland Group) compilers. The cluster is installed with ROCKS version 4.2.1 and adds on packages to the U of M computing environment.t
There are 16 compute nodes on the Linux cluster. Nodes are named using the ROCKS standard naming convention of "compute-y-x", where y is the rack number and "x" is the node's position in the rack. Since the cluster is housed in a single rack and numbering starts at zero, the nodes are named "compute-0-0", "compute-0-1", "compute-0-2", etc.
