ORNL has substantial resources located in the Center for Computational Sciences (CCS) that are of great value to SciDAC and other DOE programs.

Key among ORNL's resources are those related to storage of the massive amounts of data generated by top scientific simulations. The CCS mass storage system uses HPSS, which ORNL helped to develop. Probe is a Storage and Networking Research Facility

The CCS computers include Eagle: a 184-node IBM RS/6000 SP, Falcon: a 64-node Compaq AlphaServer SC together providing 1.5 TeraFLOPs of computing power.

New to ORNL at the time of SC2001 is Cheetah: a 27-node IBM pSeries System (just before SC2001 we accepted delivery of the first Power4 node shipped). Cheetah provides over 4.5 TeraFLOPS of computing power.

In addition to using some of the most powerful computers available today, ORNL researchers are working with IBM to help design the computers of tomorrow. Supercomputing Online article about the "Blue Gene" CRADA

ORNL is building a new Computational Sciences Building designed to house the CCS computers and staff, including projected growth in system size.

ORNL is heavily involved in networking research, including involvement in ESnet, design of the SC2001 network, and the net100 project.
