Dear Colleague Letter

Software Infrastructure for Sustained Innovation (S12) program

OCI is interested in developing a portfolio of software that best contributes to an integrated, advanced and sustainable cyberinfrastructure, which will further the research and education mission of NSF, and which leverages and extends the capabilities of major existing NSF investments.

In the context of the SI2 competition, OCI is interested in funding reusable software elements to support computational and data-enabled science and engineering through both the Scientific Software Elements (SSE) and Scientific Software Integration (SSI) categories that advance research in areas of priority across the National Science Foundation. Software in the areas of data and visualization, high performance computing and computation, and frameworks and programming environments at the SSE and SSI levels are of particular interest to OCI for the FY2011 competition.

Given the focused and crosscutting nature of the SI2 program, proposers should contact the cognizant program officers to ascertain that the scientific focus of the proposed research and the budget of the proposed effort are appropriate for this solicitation.

Questions related to the SI2 program and the FY 2011 SI2 solicitation should be directed to the SI2 working group (see https://www.nsf.gov/si2/) by sending email to si2queries@nsf.gov.
