High-End Computing Capability
Computing power to answer NASA's complex science and engineering questions
Application Optimization Services
HECC offers a range of consulting services for optimizing your application performance and productivity, in order to facilitate advances in science and engineering for NASA missions.
Our application performance and productivity (APP) experts work closely with application owners and domain specialists to make the most effective use of the high-performance computing (HPC) resources by enhancing code performance—often by an order of magnitude.
Basic Services
To request any of the following optimization services at no charge, please contact the NAS Control Room: (800) 331-8737, (650) 604-4444, support@nas.nasa.gov
- Troubleshooting issues with simulation runs
- Setting up code builds and the environment to most effectively utilize the systems, using tools and techniques such as environment variables, compiler flags, libraries, and runtime scripts
- Training in the effective use of the HECC systems including information about software modules and third-party tools (for performance analysis, debugging, visualization)
- Optimizing the performance of applications including memory reduction, cache optimization and parallel performance enhancement.
Additional Services
Our optimization experts are also available to work closely with the code owners and domain experts to conduct in-depth application analysis, and potentially undertake major code re-engineering to enhance and optimize code performance. Such services require external funding based on the required level of effort.

Record of Success
It's surprising how small code adjustments can make a large impact on code performance. Whether making simple or comprehensive code changes, the APP group's work has greatly benefited research applications for dozens of projects in all NASA mission areas. For example, the team reduced the USM3D code's runtime and memory requirements by factor of 2 to support very large computational grids. USM3D is an important computational fluid dynamics (CFD) code used for intensive aerodynamic analysis.
