Pegasus II Cluster

Pegasus II Linux Cluster overview

Design goals:

build high-performance computer system for number-crunching
support parallel computing
use cheap commodity PC hardware
employ free open-source software whenever possible
minimize total cost

Design elements:

quad core cluster server provides interface to the Missouri S&T campus network
64 diskless quad-core compute nodes (for long production runs)
32 older diskless Pentium 4 compute nodes (for test calculations and short runs)
connected via private Gigabit ethernet

Pegasus cluster can be used to run both serial and parallel jobs. Resources are administrated by the Torque batch system, and parallelization is realized using OpenMPI.
