The simulations performed in the CCRG require high performance computing. For this reason the center hosts several special-purpose cluster facilities such as:

• The "gravitySimulator," a 32-node GRAPE computer cluster with a speed of 4 Tflops and a GRAPE-6 computer cluster for gravitational dynamics simulations. The gravitySimulator was purchased in 2004 through an NSF MRI grant (PI: D. Merritt). More information about this cluster can be found here.
• The "newHorizons," a new 85-node Linux cluster with dual-processor nodes, Infiniband interconnects and a total of 1.4 Tbytes of on-board memory for numerical relativity simulations. NewHorizons has been purchased in 2007 through an NSF MRI grant (PI: M. Campanelli). See related PR and article.
• New Linux clusters for gravitational wave data analysis research and GRMHD simulations may be built in fall 2008. Special hardware facilities are also available for scientific visualization.

Scientists at the CCRG are also actively involved in research computing through TeraGrid and Open Science Grid. Our largest numerical relativity simulations are performed at TeraGrid sites, such as TACC, NSCA, etc.
