Beowulf Cluster

The groups Beowulf Cluster is a 21 node Redhat Linux cluster. Each computational node on the rack houses two quad-core AMD Operton processors, enabling the processing of a maximum 160 simultaneous threads. The cluster was acquired with intentions of running weather/climate models, necessitating increased bandwidth and hence high-speed Infiniband interconnects to all of the nodes. The cluster has a total system memory of 168 GB and 16.5 TB of storage.

Apple XServe G5 Cluster

The perenial workhorse for our models and analysis has been an 11-node (2 processors per node) Apple XServe G5 cluster. The cluster has a total system memory of 20 GB and 3.7 TB of storage.

Jaguar, Cray XT3/XT4 at NCCS/ORNL

Due to the computationally exhaustive nature of distributed modeling, inherant in WRF, tRIBS, CHILD and ED-BRAMS, several research projects utilize the massively parallel super-computing resources of the National Center for Computational Sciences (NCCS) and Oak Ridge National Laboratory (ORNL). The Bras group has ported code to (WRF-tRIBS and ED2-BRAMS) and utilized the Cray XT3/XT4 Jaguar for various high-performance endevours, including running very large/dense coupled model domains. In its transition to quad core CPUs and a Compute Node Linux OS, Jaguar is scheduled to become the first peta-scale super-computer in the world.
