Decommissioned Intel Clusters

The HPC group is working with JLab's Theory group to deploy a sequence of high performance cluster prototypes in support of Lattice Quantum ChromoDynamics (LQCD). LQCD is the numerical approach to solving QCD, the fundamental theory of quarks and gluons and their interactions. This computationally demanding suite of applications are key to understanding the experimental program of the laboratory.

Four prototype clusters have been deployed thus far, the oldest has been decommissioned:
128 Node Intel Cluster The oldest cluster, now decommissioned, was installed in 2002. It contained 128 nodes of single processor 2.0 GHz Xeons connected by a myrinet network. It achieved 1/8 TeraFlops of performance (Linpack), and also had 65 GBytes of total physical memory, and delivered 270MB/s simultaneous node-to-node aggregate network bandwidth. All nodes ran RedHat Linux Release 7.3 with kernel version of 2.4-18.
