  1. NSF Task Force on Software for Science and Engineering The Task Force on Software for Science and Engineering has formed the following major recommendations on how NSF can best support the research, development, and maintenance of software infrastructure: 1. NSF should develop a multi-level (individual, team, institute), long-term program of support of scientific software elements ranging from complex applications to tools of utility in multiple domains. Such programs should also support extreme scale data and simulation and the needs of NSF’s Major Research Equipment and Facilities (MREFC) projects. 2. NSF should take leadership in promoting verification, validation, sustainability, and reproducibility through software developed with federal support. 3. NSF should develop a consistent policy on open source software that promotes scientific discovery and encourages innovation. 4. NSF support for software should entail collaborations among all of its divisions, related federal agencies, and private industry. 5. NSF should utilize its Advisory Committees to obtain community input on software priorities.

  2. Figure 1 (Above): Software is an integrated component of the overall coordinated CIF21 framework. This figure illustrates the connections between the components of CIF21, including Software. All the components of CIF21 are generally needed to create the conditions for innovation and discovery, as shown in Figure 1.

  3. XSEDE will be: • An integrative cyberinfrastructure in which will be imbedded a range of advanced digital resources and services • XSEDE has no physical resources per se but acts as the “glue” creating an integrated distributed environment • coordinates Track 2[a,b,d], XD Viz and other XD resources • explicitly extends to involving industry in addition to academia • Accessible to researchers • directly from XSEDE systems • from their own and campus resources • from other high-end centers and cyberinfrastructure resources • via science gateways and discovery environments • Continually improved by incorporating new technologies and services to satisfy newly identified needs both from existing and emerging communities
