The Software Integration and Visualization Office (SIVO) is a program-provided activity to support NASA modeling programs. The activities include development of software environments to support collaborative research amongst a range of NASA modeling and assimilation activities. The environment will support, for example, interoperability, reuse, ease of use, and performance portability addressing the specific requirements of high-end modeling and assimilation. SIVO will promote the adoption of modern software engineering principles into the science community and will have a formal interface to the multi-Agency Earth System Modeling Framework (ESMF). SIVO will supply human resources to NASA-funded science teams in specific programs, for example the Modeling, Analysis, and Prediction Program, to assure ESMF compliance and to integrate, in partnership with members of the science team, developments and modifications into the program models. Scientific validation will be the responsibility of SIVO’s science partners.
The computational mission of SIVO will focus on high-performance computing. This will include the development of scaleable parallel software for distributed and shared memory environments. In addition, SIVO will work to develop analysis capabilities, for example visualization and data mining, suitable for high data volume modeling and assimilation activities. The computational facilities will be distributed across the nation, and analysis will require information from these facilities as well as distributed observational data systems. SIVO will represent the computational requirements of specified NASA-sponsored modeling and assimilation for computational systems design and procurement.
SIVO will provide software, data, and web services to level specified by the program office. This includes managing access into and out software repositories. SIVO will direct inquiries to appropriate science partners.
SIVO will require formal teaming with both the modeling science teams and NASA’s high performance computing organizations.
