In August 2002, a second system, this time from Wright Patterson Air Force base became operational in a new computer room with 192 nodes and 400 GB of global disk. Then in October 2003, a third system, from ERDC in Missisippi, was ready for use: 90 nodes with 1 TB of global disk replacing the system from Maui. In 2004, we installed a two BladeCenter, 28 node, cluster with from IBM. In 2005, we dismantled the Wright Patterson system and installed a 32 node cluster from IBM and a 76 node cluster from SUN, each with several TB of RAID storage. At the end of 2005 the ERDC IBM RS/6000 SP systems was dismantled to make room for the HPC Center upgrade to a 200 node, 800 dual-core Opteron cluster from Rackable with an InfiniBand switch network and 40 TB of RAID storage. Phase III of the UF HPC cluster became operational in January 2009 and brought the total to 2,500 cores and 140 TB or storage. The new cluster sits in a newly renovated machine room in Larsen Hall.
