The facility currently houses the petascale Pleiades, Aitken, and Electra supercomputers, as well as the terascale Endeavour supercomputer. The systems are based on SGI and HPE architecture with Intel processors. The main building also houses disk and archival tape storage systems with a capacity of over an exabyte of data, the hyperwall visualization system, and one of the largest InfiniBand network fabrics in the world. The NAS Division is part of NASA's Exploration Technology Directorate and operates NASA's High-End Computing Capability (HECC) Project.
