Dear Colleague Letter for Software Infrastructure for Sustained Innovation
(S12) program

   The Office of Cyberinfrastructure (OCI) has partnered with other
   directorates and offices within the National Science Foundation (NSF)
   to establish the crosscutting Software Infrastructure for Sustained
   Innovation (SI2) program ([1]http://www.nsf.gov/si2/), a long-term
   investment with the overarching goal of transforming innovations in
   research and education into software resources that are an integral
   part of cyberinfrastructure. SI2 envisions a software ecosystem that
   scales from individual or small groups to large hubs, all focused on
   innovation, development, and stewardship of a sustainable software
   infrastructure that can enhance productivity and accelerate science
   and engineering.

   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
   [2]http://www.nsf.gov/si2/) by sending email to [3]si2queries@nsf.gov.
