NETL has three clusters, none of which rank in the Top 500. One of the clusters uses 256 Intel
Xeon processors with a gigabit Ethernet interconnect. LINPACK performance is rated at 961
gigaflops, with a theoretical peak of 1,567 gigaflops. The other two clusers use AMD Opteron
processors and have lower performance.
New Brunswick Laboratory does not publicize information on their high performance computing resources.
ORNL is houses multiple powerful supercomputers, five of which are on the Top 500 list. The
computers on the Top 500 list are Jaguar XT5 (#1), Kraken (#3), Jaguar XT4 (#16), Athena
(#30), and an IBM Blue Gene/P (#379). Jaguar XT5 and Kraken are both Cray XT5 systems, while
Jaguar XT4 and Athena are Cray XT4 systems. Kraken and Athena are operated in conjunction
with NICS and the University of Tennesse. In addition to the five Top 500 computers, ORNL
has many smaller high performance computing systems.

OSC has two HPC clusters: Glenn, and OSC BALE. Glenn is ranked at 107 on the Top 500 list,
while OSC BALE does not rank. OSC BALE consists of two subclusters - an eighteen node
visualization cluster and a workstation cluster. The visualization nodes each have two
dual-core AMD Opteron CPUs at 2.6GHz, and two NVIDIA Quadro FX 5600 graphics cards. The
workstation nodes each have a single AMD Athlon X2 4200+ dual-core processor. Both the
visualization and workstation machines use Infiniband as their interconnect.
