The WorldWinds HPCC cluster has 32 rack-mounted processors running a standard Linux distribution for a total of sixty-four (64) virtual processors. Each of the 32 dual-core Dell 64-bit Xeon processors features an Intel 7520 chipset, 3.0GHz processor speed, 2GB DIMM, and a 36GB hard drive.

In order to be flexible enough to incorporate new models as they become available, WorldWinds' cluster is configured with several different parallel processing environments. The operating system and libraries run the COAMPS, MM5, and WRF atmospheric weather models and the ADCIRC 2-D hydrographic dynamic model; they are also able to run any distributed application based on either the LAM or MPICH implementation of the Message Passing Interface. The system is designed to be highly scalable in order to boost performance and capacity. Additionally, the WorldWinds cluster uses a parallel compiler from the Portland Group for increased performance on each node of the cluster.

All nodes and supporting equipment, including battery back-ups, are mounted in a PowerEdge 4210 rack with spare capacity. WorldWinds has also purchased a 3-year on-site, same day replacement contract for parts and labor, should any of the equipment require maintenance.

WorldWinds' facility services are completely redundant. The DoD constructed facility includes multiple power source feeds, a full-building uninterruptible power supply, and a generator capable of sustaining operations indefinitely. Adding to this is an entirely redundant cooling system that results in an optimum environment for operational modeling with a nearly zero chance of down time. The Slidell, LA facility continued to be fully operational during and after Hurricane Katrina even though the area suffered a direct strike by a major hurricane.
