  1. GEC17: GENI Instrumentation and Measurement Sessions Sun. July 21, Mon. July 22, 2013 Marshall Brinn, Jeanne Ohren GPO

  2. Outline • We will be holding two sessions at this GENI Engineering Conference (GEC) to focus on the I&M efforts • [1] I&M: Topics and Status [Sunday 7/21 1030-1200] • [2] I&M: Looking Forward [Monday 7/22 1330-1530] • The goal of these sessions are to take a short-term and long-term view of the I&M project • [1] Where are have we gotten to? What are our current status and issues? What are our natural next steps? • [2] Where should we try to steer to I&M effort in the remaining project scope?

  3. Focus on the Experimenters • As we take stock on the I&M efforts and try to plot the path forward, try to keep the needs of experimenters in the front of your minds • The ultimate metric of our success is the degree to which we’ve helped experimenters use GENI to pursue their research • Remember that we’re trying to support two populations: • “Power Experimenters”: Knowledgeable researchers who want to use the full power of GENI and the I&M tools to perform large-scale, highly customized, complex experiments. • “Beginners”: Grad-students or even undergraduates who are relatively new to network research and for whom we want to provide an easy path to do reasonably interesting/enlightening things.

  4. Session 1: Sunday 7/21/2013 1030-1200 I&M: Topics and Status

  5. Outline • For both GEMINI and GIMI [15 minutes each] • Discussion of current status and issues • Where are we at? • What’s been good or hard in developing or integrating your capability? • What might you suggest we do differently technically, or administratively? • Sneak-peak at tonight’s demo sessions: What will you be highlighting?

  6. Outline [2] • [30 min.] Looking for opportunities for value-added contributions: • What functionality (from your own I&M effort) do you think could provide significant value to other I&M efforts or GENI services (Clearinghouse, tools, aggregates)? • What functionality (from other I&M efforts or other GENI services) would you like to leverage to strengthen your offering to experimenters?

  7. Discussion

  8. Session 2: Monday 7/22/2013 1300-1530 I&M: Looking Forward

  9. Outline • Try to imagine what your demo at GEC18 should or could look like • Or perhaps GEC19 or GEC20… • What additional kinds of interoperability and collaboration between I&M and other GENI services could be developed to enhance experimenter experience? • Specifically, how can GEMINI and GIMI leverage and integrate each other’s capabilities to provide uniform and value-added services?

  10. Motivation This second session is to encourage out-of-the-box thinking about the I&M effort and where we’re at and where we might or should go from here. • We hope we can all step back and rethink a little of our approach and direction, as appropriate. • Obviously we don’t want to change for change’s sake • Nor do we want to derail the good progress being made on all fronts. • But if there are “low hanging fruit” that we can identify that would provide good value to experimenters, we should try to identify and pursue them.

  11. Some “provocative” thoughts • GIMI has a strong orchestration story through OMF • Could GEMINI benefit from taking advantage of the GIMI OMF framework? • GEMINI has a strong set of topology and measurement services • Could GIMI benefit from integrating some of these services into the GIMI portal or services?

  12. Some “provocative” thoughts [2] • GEMINI Desktop uses ssh to configure resources, while GIMI uses OMF (over XMPP). • Can we discuss the relative strengths/weaknesses of these two approaches? • From both a developer and particularly an experimenter perspective? • Both GIMI and GEMINI use iRODS as their essential experimental result store. • Is there something to be gained from leveraging this common feature (some way to communicate between systems e.g.)? • Could we benefit from re-focusing on common data descriptions?

  13. Some “provocative” thoughts [3] • What is the right level of explicit ‘programming’ that should be required to manage different experiments: • Should simple experiments require simple programs or no (visible) programs at all? • Should complex experiments be driven by programs or something more like a user interface? • Is there more we can or should be doing to improve reproducibility of experiments? • Capturing the running environment configuration, run-scripts, control parameters, etc.

  14. Discussion
