NASA High-End Computing Capability (HECC)

HECC provides specialized supercomputing systems and services that meet NASA's unique science and engineering needs more effectively and affordably than would otherwise be possible. As a result, NASA and its partners are able to produce enormous returns on scientific knowledge, engineering achievements, and technological advancements that support NASA's strategic goals and benefit our nation and global community. HECC systems are specifically architected for optimal performance of advanced science and engineering applications, and HECC support services enable users to get the most productivity out of the systems through custom code optimization, analysis tools, and data visualization capabilities. As a result, science and engineering analyses are able to run more efficiently and at higher fidelities than they could on a more generic, commercial system. HECC's readily available computing resources also reduce overhead by enabling scientists/engineers to focus on productive research rather than wasting valuable time finding potential supercomputing providers, budgeting for the variable costs, and implementing/debugging codes on less ideal external systems. HECC also continually drives down the cost of computing time by augmenting the available resources with faster, more efficient systems. HECC provides rapid, high fidelity simulations for projects like:-NASA's Space Launch System like Simulations of predictions of liftoff acoustics, ignition over-pressure, separation environments, debris, Launch Pad Abort Environments and hydrogen entrapment.-In Aeronautics, HECC supports simulations of Large Eddy Simulations(LES) and Direct Numerical Simulations (DNS) for hydrocarbon combusting flows. Simulations will validate chemistry, chemistry-turbulence and spray models being developed.-In Heliophysics, understanding the magneto-dynamics of the solar surface, the emergence of magnetic flux and the formation of active regions.
