ADVANCED SOFTWARE & TECHNOLOGY GROUP

The Applications Software Technology Group (ASTG) provides custom high-performance computing (HPC) support to NASA-funded researchers. The ASTG team consists of HPC experts from a variety of disciplines including meteorology, physics, mathematics and several areas of engineering. ASTG services include training, parallelization, algorithmic improvements, optimization, porting, and software design/implementation. ASTG clients include the Goddard Institute of Space Studies (GISS), the Global Modeling Initiative (GMI), the Global Modeling and Analysis Office (GMAO), and NASA's Modeling, Analysis, and Prediction (MAP) Program.
