GIMI v1.0 Architecture for GEC 14 Tutorial

GIMI v1.0 Architecture for GEC 14 Tutorial

This document gives an overview of the GIMI v1.0 architecture as it is planned to be in place for the tutorial at GEC 14.

After review on 5/23/12.

General

The tutorial is limited to a maximum of 30 attendants. Two attendees will be working as a team during the tutorial. Like the DICloud tutorial, there will be several members of the GIMI team there to allow us to pay sufficient attention to each individual.

To do:

  • Confirm that the GIMI tutorial will be preceded by an ORCA/ExoGENI tutorial.
  • What will be exact date and time of the ORCA/ExoGENI tutorial? (Mon, 7/9, ~10:30am) Of the GIMI tutorial? (Mon, 7/9, ~1pm)
  • We need 15 accounts. To make things easy we should have the same account and PW across all GIMI tools. Proposal: gimitut1-15, gec$14
  • Prepare tutorial script, and put on GENI wiki
  • Consider ongoing support for tutorial, to provide a “GENI at home course”.

Tutorial length: 1 1/2 hours

Topic Duration
iRODS Intro 15 minutes
IREEL Intro 15 minutes
Measurement Tutorial 60 minutes

ExoGENI

  • For the tutorial users will be given a pre-defined ExoGENI topology. Some of these topologies (approximately 3-4) will be inter rack slices (two aggregates), the others will be intra rack slices (one aggregate).
  • We will give a short (approximately 30 minutes) introduction on how resources can be obtained with either Flukes or Omni. This will be canceled if an ExoGENI tutorial precedes our tutorial at GEC14.
  • Due to time limit we will use per-configured ExoGENI machine images. Users will have to learn otherwise how to generate and configure images.
  • The pre-configured images will include (5/25): o OML 2.7.0 o OMF 2.7.0 o OML-ified Iperf o iRODS 3.1 client o web server (small apache) o r (for visualization) o also EC?

To do:

  • Review GEC 13 ExoGENI tutorial slides.
  • Coordinate with GEC14 ExoGENI tutorial.
  • Create accounts that can be used to access ExoGENI resources (6/15)
  • Pre-configure 15 ExoGENI slices on aggregates (define rspecs) (6/15)

OMF/OML

  • Run OML server on one of the ExoGENI nodes (5/25).
  • Use OML-ified Iperf for throughput measurements between ExoGENI nodes (5/25)
  • Use nmetrics to monitor condition of single node (5/25)
  • OMF EC to execute measurement (5/25)
  • Collect data on MC (5/25)

To do:

  • How to bring up desired services on selected nodes? (6/1)
  • Decide on what XMPP server to use. NICTA, Rutgers, UMass? (5/25)
  • Decide how to load info into XMPP server. (6/1)
  • Provide for visualization on MC (6/1) How?

iRODS

  • Persistent iRODS servers are already setup at UMass and RENCI (with RENCI running iCAT).
  • Measurement data collected at MC will be transferred to iRODS (6/1).
  • Users will be able to use IREEL to analyze and present data stored in iRODS (6/15).

To Do:

  • Create iRODS accounts for tutorial users (6/1)
  • We should give a short (approximately 30 minutes) iRODS intro during the tutorial. MZ: Still possible with in 90 minutes time slot?

IREEL

  • Use IREEL as measurement portal (6/1)
  • Persistent portal will be set up at UMass Amherst (6/15)

To Do:

  • Implement Flukes/Omni interface (TBD) MZ: Do we want to do this for tutorial?
  • Implement iRODS interface (6/15)
  • Can GENI credential mechanism be used? – Most likely not for tutorial!

VirtualBox

  • It would be great if we could have an independent (of other tutorials) VirtualBox image; on 5/23, it appears that only GIMI and GEMINI require VirtualBox, so perhaps have one image for both.
  • VirtualBox image for testing (6/1, Jeanne)
  • Required SW: o Flukes o Omni o iRODS client o Web browser o EC

To Do:

  • Is there a way to pre-install all required credentials?
  • What Java version does Flukes require?

Applications

  • Time-series radar data: measure throughput of time-series data?
  • Video: measure jitter of video data?
  • TCP/UDP experiment from IREEL, Guillaume?
  • Multi-path TCP?
  • Energy consumption?

To Do:

  • Pick a good application, or “reference experiment” (6/1)
  • Prepare a reference use case (6/1)
