  • NCCS is only for SMD. NAS shared Pleiades and Columbia is now 52% for SMD and 48% for other MDs, earlier Pleiades, Columbia, and Schirra 50% for SMD, 50% for other MDs since 12/09, 40%/60% prior. NAS Columbia had adjustable allocations for the SCIENCE and SEAS domains; a 512 CPU sections was re-allocated from SEAS to SCIENCE early in April, 2009. NAS began retiring the Y2004 racks of Columbia in late April through early June 2010; 2048 of the remaining are ESMD only, the remaining 2560 CPUs are open to all users with nominal shares of 52% for SMD and 48% for other MDs. RT Jones was removed at the beginning of April 2010 and Schirra was decommissioned in late July 2010.
  • Discussed with SMD management in November, 2012
  • Foundation for fifth-generation architecture. Change economies and scaling properties. [no more on this slide]
  • Note that the citations plot only include papers published over the past 3 years, which have not reached their ultimate citation impact yet. If we look at all years: HST (36 cites), IUE (34) both have > 30 citations/paper; FUSE 23, GALEX 20 (but it is a younger mission), Kepler 12, Other 34 -Probably GALEX and Kepler will ultimately have >30 cites/paper on average. -Note that library staff did some research to try and determine reason for dip in 2008/2009 time frame and many observatories noticed the dip.
  • -Projected growth in GALEX is from addition of photon data -The tick marks in the plot above mark the end of the calendar years (which is why the projected line appears in the middle of 2010)

    18. 18. NAC Committee on IT Infrastructure Recommendation #1♦ Recommendation: To enable NASA to gain experience on emerging leading-edge IT technologies such as: − Data-Intensive Cyberinfrastructure, − 100 Gbps Networking, − GPU Clusters, and − Hybrid HPC Architectures, we recommendation that NASA aggressively pursue partnerships with other Federal agencies, specifically NSF and DOE, as well as public/private opportunities. We believe joint agency program calls for end users to develop innovative applications will help keep NASA at the leading edge of capabilities and enable training of NASA staff to support NASA researchers as these technologies become mainstream.
    19. 19. NAC Committee on IT Infrastructure Recommendation #1 (Continued)♦ Major Reasons for the Recommendation: NASA has fallen behind the leading edge, compared to other Federal agencies and international centers, in key emerging information and networking technologies. In a budget constrained fiscal environment, it is unlikely that NASA will be able to catch up by internal efforts. Partnering, as was historically done in HPCC, seems an attractive option.♦ Consequences of No Action on the Recommendation: Within a few more years, the gap between NASA internally driven efforts and the U.S. and global best-of-breed will become a gap to large to bridge. This will severely undercut NASA’s ability to make progress on a number of critical application arenas.

    35. 35. NAC Committee on IT Infrastructure DRAFT* Recommendation #2♦ Recommendation: NASA should formally review the existing national data cyberinfrastructure supporting access to data repositories for NASA SMD missions. A comparison with best-of- breed practices within NASA and at other Federal agencies should be made.♦ We request a briefing on this review to a joint meeting of the NAC IT Infrastructure, Science, and Education committees within one year of this recommendation. The briefing should contain recommendations for a NASA data-intensive cyberinfrastructure to support science discovery by both mission teams, remote researchers, and for education and public outreach appropriate to the growth driven by current and future SMD missions. * To be completed after a joint meeting of ITIC, Science, and Education Committees in July 2012 and the final recommendation submitted to July 2012 NAC meeting
    36. 36. NAC Committee on IT Infrastructure Recommendation #2 (continued)♦ Major Reasons for the Recommendation: NASA data repository and analysis facilities for SMD missions are distributed across NASA centers and throughout U.S. universities and research facilities. • There is considerable variation in the sophistication of the integrated cyberinfrastructure supporting scientific discovery, educational reuse, and public outreach across SMD subdivisions. • The rapid rise in the last decade of “mining data archives” by groups other than those funded by specific missions implies a need for a national-scale cyberinfrastructure architecture that can allow for free-flow of data to where it is needed. • Other agencies, specifically NSF’s Ocean Observatories Initiative Cyberinfrastructure program, should be used as a benchmark for NASA’s data-intensive architecture.♦ Consequences of No Action on the Recommendation: The science , education, and public outreach potential of NASA’s investment in SMD space missions will not be realized .
