Linux Cluster Information

Welcome to, the small linux cluster operated by the Widom research group in the CMU Physics Department.


The cluster consists of intel-based nodes (head node, file server and compute nodes) running SUSE 9.3 Linux, linked with gigabit ethernet for parallel processing. Jobs are run using the PBS queueing system, including the MPICH message passing interface for parallel processing. Click here for a complete list of nodes and their characteristics.


The following sections describe the principle software packages available on the system:

Compilers and programming tools
Graphing and visualization
Electronic structure codes
Simulation tools
Locally developed scripts and tools
