The NAS facility at Ames Research Center was established in the early 1980s by Congress with a charter to provide high-end computing capabilities for performing numerical simulations of proposed commercial and military aircraft designs. Since then, NAS has continually adapted to meet NASA’s changing needs, including the installation and expansion of Pleiades, a world-class supercomputer now capable of 5.33 petaflops (5,330 trillion floating-point operations per second) of peak performance.

The sponsorship for NAS is from the High-End Computing Capability (HECC) Project, which is funded through the Strategic Capabilities Assests Program and managed by the High-End Computing (HEC) Program. With Pleiades, the HEC Program has enhanced performance and better facilitated groundbreaking science and engineering in support of all four NASA mission directorates.

NAS’ integrated resource and service offerings include high-speed networks, archival storage systems, system performance and application optimization, 24x7 user services operations, data analysis, and scientific visualization. In parallel with supercomputer growth, NAS continually develops advanced visualization techniques. NAS has deployed a cutting-edge visualization system, hyperwall-2, which is connected directly to supercomputers, allowing scientists to run more sophisticated concurrent visualizations.
