1. Sponsored by the National Science Foundation GEC16 Service Developers Roundtable: Strawman Unified I&M Tools and Services Marshall Brinn, GPO March 19, 2013

2. Sponsored by the National Science Foundation2 Overview Goal: Provide researchers with an intuitive, powerful set of tools to support experimentation Problem: We have two different families of tools (GIMI, GEMINI) that have different architectures, interfaces and are (currently) focused on different compute platforms Solutions: –Make all services available on all platforms –Provide common ‘base’ interface that allows experimenters to manage experiments in a platform- agnostic manner

3. Sponsored by the National Science Foundation3 I&M Proposed Simple Common API # Let's keep it very simple. # Something like: # Open a session for storing metrics session_url <= open_session(session_name) # Closea session for storing metrics status <= close_session(session_url) # What are the metrics I can ask for onthis platform? metric_names <= available_metrics() # What are the attributes for agiven metric attributes <= metric_attrributes(metric_name) # Start metric capture # Specify attributes tailoring the nature of capture (frequency, detaile.g) metric_capture_id <= start_metric_capture(session_url, metric_name, attribs) # Stop metric capture success<= stop_metric_capture(session_url, metric_capture_id) # Gather all data for agiven session # Optionally filtered by attributes of matchingmetric types data <=grab_session_data(session_url, attributes=None)

4. Sponsored by the National Science Foundation4 I&M Proposed Simple common API Clearly this is a simple API, and one can do much more with either GIMI and GEMINI than is available through this API. –Haven’t discussed common analysis or orchestration, e.g. –Nor have we touched on common resource topology allocation There is considerable non-uniformity in this area as well –But it is a starting point and we can add to it as we go Just getting this basis established will be a major win for the experimenter community –Supporting common scripts that can run on ANY GENI topology provided from ANY GENI aggregates.

8. Sponsored by the National Science Foundation8 I&M We know that there are two different I&M tool suites being developed and deployed: GIMI and GEMI –Each is developed on one platform, and is slated to be ported to the other platform this year (though personally I think this is a stretch). I would like to define a common set of API’s that will be available on any GENI image supplied by GENI racks.

9. Sponsored by the National Science Foundation9 I&M : Proposal I suggest we write a simple API for generic I&M support –And then write implementations of this API that run on any given image. –The image may support this implementation with GIMI or with GEMINI (or perhaps a hybrid)

10. Sponsored by the National Science Foundation10 I&M [3] There’s lots more to do in this area (Orchestration, data analytics, etc.) But I think this is a very good start and if we only do this much we’ll have done a lot. This effort is likely to be less in the hands of the Architects than in the members of the different I&M teams. But I want us to monitor and encourage this kind of common functionality.
