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.
FEATURED PROJECTS
- Application Controlled Parallel Asynchronous Input/Output (Asynch I/O)
- An MPI-based Parallel Asynchronous I/O (PAIO) software package that enables applications to balance compute and I/O resources directly
- Cubed-sphere Finite-Volume Dynamical Core (fvcore)
- Implementation of the fvcore, a key component of global models at NASA, NOAA and NCAR, on the quasi-uniform cubed-sphere grid with a 2-dimensional horizontal domain decomposition
- Fast Fortran Transformation Toolkit (FFTT)
- A tool to enable model developers to create test "harnesses" for legacy software written in Fortran
- Goddard Institute for Space Studies (GISS) ModelE
- Collaborating with the developers of ModelE, a coupled atmosphere-ocean model, to improve and extend the model in a variety of ways
- Global Modeling Initiative (GMI)
- Supporting the development and integration of a state-of-the-art modular 3-D chemistry and transport model (CTM) that includes full chemistry for both the troposphere and stratosphere
- GUI-Based Workflow Tool
- Built on top of a popular tool developed by the European Centre for Medium-Range Weather Forecasts (ECMWF), SIVO is developing an end-to-end modeling Workflow Tool for NASA scientists and researchers.
- Modeling Guru
- A web-based research and collaboration resource for the scientific model development community. Modeling Guru is intended as a central repository where users can communicate with each other and find information related to the many aspects of scientific modeling development and NASA’s High-End Computing Systems.
- Modeling Snowflake Growth
- Modeling snowflake growth as part of research into retrieval
of precipitation and
cloud microphysical properties
- pFUnit
- A Fortran testing framework utility developed by SIVO that is available to the general public through a NASA Open Source Agreement
