Introduction 
Texas Tech University's High Performance Computing Center (HPCC) was established in 1999 to promote research and teaching on campus through integrating leading-edge high performance computing and visualization for the faculty, staff and students of Texas Tech University.
The HPCC provides consulting and assistance to campus researchers with experimental software and/or hardware needs. We also provide training in parallel and grid computing (as used at the facility) and administration for local high performance systems. HPCC serves as a liaison between various teams that are engaged in research. We work to support, configure and port applications to HPCC resources.
HPCC has computational resources which include several Linux clusters and a grid computing environment. Our newest computational resource, Antaeus, is a Dell Linux Cluster that consists of 192 3.0GHz processors with 2.3 Teraflops of peak performance. Antaeus was purchased as a joint effort between HPCC & TTU IT Division, the TTU High Energy Physics (HEP) Group, and the Hase Research Group. Jobs can be submitted to this cluster using grid middleware.
Another computational resource available through HPCC is Hrothgar. Recently upgraded, Hrothgar is a Dell cluster of 64 dual 3.2 GHz Xeons and 64 2.33 GHz dual quad-core Xeons. It has an Infiniband network to provide 10GigE bandwidth and low latency communications. Hrothgar is one of the major high performance computing resources available for TTU students and faculty. Hrothgar has a total of 1 TB of memory.
Both systems use Lustre to provide high availability and high bandwidth storage. Antaeus has 6TB of shared storage for all users and 10TB of scratch space for HEP group. Hrothgar has 12TB of shared storage.
Additionally, TTU participates in local, regional and national grid projects. A local resource is TechGrid which consists of more than 300 CPU's.
