Physics Computing Resources:

Condensed Matter Theory (CMT)

  • AMD Opteron Cluster (2.0 GHz-2.4GHz): This is a distributed memory cluster composed of 121 dual nodes (i.e. 242 CPUs) with 32 nodes having 4 GB memory/node and 88 nodes having 2 GB memory/node (i.e. a total memory of 308 GBs). Clock speeds of the Opteron cluster range from 2.0 GHz to 2.4 GHz (master node@2.4 GHz, 32 nodes@2.2 GHz, and 88 nodes@2.0 GHz). The nodes are linked via gigabit ethernet connections. A 700 GB raid array system is also available for the home directory files.
  • AMD Athlon MP Cluster (1.6 GHz - 2.1 GHz): An older Linux cluster with 56 compute nodes, 56 GB of memory, and 200GB of the raid array.
  • SGI ALTIX 350 System (Intel Itanium-II): Two shared-memory computers, (clock speeds of 1.4 GHz and 1.5GHz, respectively), each with 16 CPUs, 64 GBs of memory, and 274 GBs of storage.
  • SGI ALTIX 450 System (Intel Itanium-II): A symmetric multi-processing (SMP) system with 64 GBs of shared memory, 16 CPUs, and 800 GBs of storage.

Comparative Planetology Laboratory (CPL)

  • AMD Opteron Cluster (2 GHz): This is a 64-core linux parallel computer cluster composed of 3 nodes.

University-wide Computing Resources

  • IBM iDataplex (Intel Xeon L5420, 2.5 GHz): This distributed memory cluster will have 312 nodes with quad core processors for a total of 2496 processor cores. Each node has 32 GBs of memory and the nodes will be interconnected by a mixture of Gigabit Ethernets and infiniband (16 Gps) technology. This cluster is expected to have a peak performance of 20+ teraflops.
  • IBM P570 (Power 6, 4.7 GHz): This is a SMP system with 16 CPUs and 128 GBs of shared memory.



Congratulations to Dr. Raymond Chastain

Congratulations to Ray Chastain who has been nominated as the “Top 4” Faculty Favorite of 2013-2014. His accomplishments will be recognized through a short video interview that will be featured in UofL Today in early 2015.


Dark Interactions Workshop Brings Global Physicists to Brookhaven Lab

A UofL physicist participated in the "Dark Interactions Workshop" at the U.S. Department of Energy’s Brookhaven National Laboratory, and his talk was highlighted in reports from the lab.
