I&M Design Topics at GEC16

Tuesday, March 19, 10:30am - 12noon
Room:
Session leader: Harry Mussman (GENI Project Office, Raytheon BBN Technologies)

Description

This I&M session will focus on the key issues of interest to both the GIMI and GEMINI projects, as they continue to work towards a comprehensive set of I&M tools for GENI experimenters and for infrastructure measurement. In particular, we will consider the services and functions that can be used by both the GIMI and GEMINI projects.

We will form teams that can resolve these issues.

Finally, we will discuss the I&M goals for the next 4 months, particularly how to best support experimenters and those doing infrastructure measurement.

Pre-Requisites

None

Agenda

This is a tentative agenda, which may change.

1) Introductions

8:30am

2) Meeting Introduction

8:35am
Harry Mussman (GENI Project Office)

Today’s discussion topics:

Goals and Approach

  • Work towards a "unified experiment environment".
  • Help groups prepare responses to Sol 4

Current overall experiment configuration

Summary of current experiment steps

Possible next steps towards a “unified experiment environment”.

Today’s discussion topics:

  • Support GIMI and GEMINI I&M tools on both ExoGENI and InstaGENI racks
  • Use instrumentize script, driven by rspec extension, to configure/init I&M tools
  • Options for further measurement data analysis and presentation

3) Support GIMI and GEMINI I&M tools on both ExoGENI and InstaGENI racks

8:40am

Overview

Step 3: Obtain slice, install software

  • Now: GIMI using ExoGENI, Flukes; loads images/pkgs
  • Now: GEMINI using InstaGENI, FLACK; loads images/pkgs

Next: be able to use GEMINI on ExoGENI, and GIMI on InstaGENI

Suggest: set goal to begin testing all combinations starting 5/1; good support by GEC17

Lessons learned from using GIMI tools on ExoGENI racks

Discussion

15min Cong Wang; Hussam Nasir; (Ilia Baldine); (Rob Ricci); Louisa Nevers; Jeanne Ohren

Discuss:

  • Goal to begin testing all combinations starting 5/1; good support by GEC17
  • Likely roadblocks
  • Suggested approaches

Any topics, suggestions and issues suggested AHEAD OF TIME by members of roundtable?

At the end: any conclusions, list of issues, team to continue discussion]

4) Use instrumentize script, driven by rspec extension, to configure/init I&M tools

9:15am

Overview

Step 4: Configure/init I&M and exp app

  • Now: GIMI using post boot scripts, OMF
  • Now: GEMINI using instrumentize script, choices based on rspec extension; also used to add GN

Next: move towards common approach, to better unify experiment environment

Suggest: both move towards script, driven by rspec ext; discuss at I&M session

Current GIMI use of post boot scripts, OMF, to configure/inti services

5) Options for further measurement data analysis and presentation

9:40am

Overview

Step 6: Analyze

  • Now: Both GEMINI and GIMI push measurement data objects (files) to GENI Storage Service (iRODS)
  • Now: GEMINI provides dump of mongo DB, plus separate file of metadata
  • Now: GIMI (will) provide SQLdump of PostgreSQL DB, which includes metadata
  • Now: Both use portal on GENI Storage Service (iRODS) to curate files (objects)

Both: Pull measurement data files from GENI Storage Service (iRODS) back to user workspace, where DBs can be reconstituted, and data pulled for further analysis and presentation.

Both: Many options for further analysis and presentation, not being developed as part of tools.

Next: Consider possible ways to unify data formats, analysis and presentation

Suggest: Discuss what might be possible, and potential approaches at I&M session
