  1. Grid Technologies Update

  2. Question “What would you want the CIO of a research campus, or perhaps this particular group of CIOs, to know or anticipate or think about with regard to grid infrastructures, grid technologies, grid communities, or related?”

  3. Answerers - Grid Charlie Catlett, ANL CIO, former TeraGrid director Bob Cowles, SLAC & Open Science Grid Ian Foster, UChicago/ANL, Computation Inst. Von Welch, NCSA, GridShib PI Christoph Witzig, SWITCH & EGEE

  4. Answerers - Campus Jill Gemmill, Clemson, Director of Virtual Organization & Exec Dir for CI Technology Integration David Lifka, Cornell’s Center for Advanced Computing Jim Pepin, Clemson central IT John Paul Robinson, UAB central IT Renee Schuey, Penn State central IT

  5. Answerers - Unclassifiable Ken Klingenstein, Internet2, Colorado & OGF

  6. What is a grid? Jim Pepin says • app level software • hardware shares • colocation of services • condo services • Grids are evolving towards 'social networks' as well.

  7. Why Bother with Grids? Christoph Witzig says There are advantages for making grids more available to the average scientist (not just HEP): • better use of resources • access to platforms not available at the local institute • lead to better collaboration between institutes and individual scientists  ("the social aspect of science") Particularly smaller institutions with less resources could profit and pool their resources.

  8. Charlie Catlett says "I think the biggest issue folks should think about, and try to solve, is identity management."

  9. Campus IdM & Grids Christoph Witzig puts it thusly Key is the integration of campus identity management systems with grids and making the access seamless. Rolling-out PKI credentials to everybody is not a viable option. Grids also need integration with campus networks if they want to expand their user base drastically - so there is also interest on the grid side for integration. It's not a one way road.

  10. Who Will Lead IdM? But Charlie worries … we found that this was the thing that tripped us up more than anything else [referring to interop testing among several large grids]. I thought, a year ago, that the campus community (EDUCAUSE/I2) might be solving this but found (at Snowmass in Aug 2006) that this was not the case. … 15 or 20 campuses in the room saying "gee this is really hard and we have not figured it out".

  11. Common Trust Anchors Christoph Witzig notes Proper accreditation of a "automated credential translation" from local credentials to X.509 is very important in order to avoid disconnected "islands of identity".

  12. (Campus?) Attributes Von Welch says When someone goes through the whole NSF allocation process [for TeraGrid] they need to be vetted as a member of a valid institution. Then over the longer term NSF tracks its user community as they move from undergrads, to grad students, to faculty and how their usage progresses.

  13. Bob Cowles says "Would you want to fly in an airplane designed using the Storm botnet?"

  14. Shared Resources Require Shared Policy "The policy / procedure stuff is REALLY tough. " … the resources contributed to the grid need to be of high quality and that means getting your site central infrastructure people involved - and convincing them they have to do things differently now because they have to have consistent policies (at least for the grid part) as all the other institutions. They are NOT used to operating in that manner."

  15. John Paul Robinson’s principles • Respect Autonomy • Good Standards Don't Dictate Implementations. This same goal should be applied to policies. • Charge Back Models Can Be Harmful • If your customers are captive (not autonomous) and your policies (poorly written) prevent them from exploring alternate solutions they will eventually revolt.

  16. Ken Klingenstein relays a European impression: "If you want grant funding, don't mention Grids."

  17. Niche? And he muses Grids are settling into a small, real but real small, niche. The last few NSF purchases have been for big honking computers that might plug into Grids but might not. What are the messages here? The campus more than the national Grids deserve some play.

  18. Readiness Test David Lifka takes the researcher’s perspective Are there valuable resources "out there" that make this a reasonable option for my research? Is the effort required to get my codes working on the grid really worth it? If I take the time & effort necessary to use the grid will I have priority when I need it? Will there be so many available resources that I'll never have to wait?

  19. Ian Foster says Universities that want to be competitive in research need to enable their faculty to participate fully in such endeavors. [referring to increasingly data- and compute-intensive practices for science & scholarship]

  20. Enable How? On-demand access to substantial amounts of computing and storage (think Amazon EC2 and S3) Campus grids that provide access to centralized resources (e.g., Purdue) or federate across groups (e.g., UCLA) Universities host Web pages for their faculty and students--they also need to think about hosting datasets and services Identity services, Wikis, other collaboration tools Expertise to help develop and/or install and operate new applications Participating in Open Science Grid could be a good start for many campuses

  21. Campus Grid/CI Jill Gemmill asks What CI functions are occurring within schools and departments, perhaps poorly or in jeopardy, because those functions are not available from you? Would your institution benefit from centralization of these functions? Are you able to participate as a partner in grant generating activities and receive an allocation of indirect costs? How can your directory services / authN/Z / provisioning be leveraged for these types of projects?  Ditto for storage.

  22. CIO Reflection Renee Schuey leads us in reflection What's in it for my institution? What do we have to do to be a user of a grid? A contributor to a grid? What are the risks of facilitating grid work? What are the benefits to faculty on our campus? How would I find out if there are faculty on our campus already using grids - and who we might be able to help use them better if we only knew?
