FASTMath SciDAC Institute
Software Catalog

Much of our knowledge and experience is embodied in the FASTMath software tools, many of which are Department of Energy (DOE) landmark packages that are widely available and used by DOE and other application scientists. A strength of the FASTMath project is its ability to build a more integrated, high-performing software base for applications, while sharing software development best practices internally and across DOE. To fully realize this potential, we must bring together software products with varying degrees of interoperability, maturity, robustness, and user support. We have already started efforts to this effect in the SciDAC-3 FASTMath and QUEST Institutes. We will continue these efforts in SciDAC-4 to improve quality, reduce barriers to adoption, and facilitate integration of the many FASTMath software products. 

A list of FASTMath software tools is provided here, along with links for further information and for downloading the software packages.
