== 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.  [[BR]]

After review on 5/23/12.  [[BR]]

=== 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:  [[BR]]

 •	Confirm that the GIMI tutorial will be preceded by an ORCA/ExoGENI tutorial.  [[BR]]
 •	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)  [[BR]]
 •	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  [[BR]]
 •	Prepare tutorial script, and put on GENI wiki  [[BR]]
 •	Consider ongoing support for tutorial, to provide a “GENI at home course”.  [[BR]]

Tutorial length: 1 1/2 hours  [[BR]]

 Topic	Duration  [[BR]]
 iRODS Intro	15 minutes  [[BR]]
 IREEL Intro	15 minutes  [[BR]]
 Measurement Tutorial	60 minutes  [[BR]]


=== 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). [[BR]]
 •	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. [[BR]]
 •	Due to time limit we will use per-configured ExoGENI machine images. Users will have to learn otherwise how to generate and configure images. [[BR]]
 •	The pre-configured images will include (5/25): [[BR]]
  o	OML 2.7.0 [[BR]]
  o	OMF 2.7.0 [[BR]]
  o	OML-ified Iperf [[BR]]
  o	iRODS 3.1 client [[BR]]
  o	web server  (small apache) [[BR]]
  o	r (for visualization) [[BR]]
  o	also EC? [[BR]]

To do:  [[BR]]
 •	Review GEC 13 ExoGENI tutorial slides. [[BR]]
 •	Coordinate with GEC14 ExoGENI tutorial. [[BR]]
 •	Create accounts that can be used to access ExoGENI resources (6/15) [[BR]]
 •	Pre-configure 15 ExoGENI slices on aggregates (define rspecs) (6/15) [[BR]]
 
=== OMF/OML ===
 •	Run OML server on one of the ExoGENI nodes (5/25). [[BR]]
 •	Use OML-ified Iperf for throughput measurements between ExoGENI nodes (5/25) [[BR]]
 •	Use nmetrics to monitor condition of single node (5/25) [[BR]]
 •	OMF EC to execute measurement (5/25) [[BR]]
 •	Collect data on MC (5/25) [[BR]]

To do:  [[BR]]
 •	How to bring up desired services on selected nodes?  (6/1) [[BR]]
 •	Decide on what XMPP server to use. NICTA, Rutgers, UMass? (5/25) [[BR]]
 •	Decide how to load info into XMPP server.  (6/1) [[BR]]
 •	Provide for visualization on MC (6/1)  How? [[BR]]
 
=== iRODS  ===
 •	Persistent iRODS servers are already setup at UMass and RENCI (with RENCI running iCAT). [[BR]]
 •	Measurement data collected at MC will be transferred to iRODS (6/1). [[BR]]
 •	Users will be able to use IREEL to analyze and present data stored in iRODS (6/15). [[BR]]

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

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


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

 === 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. [[BR]]
 •	VirtualBox image for testing (6/1, Jeanne) [[BR]]
 •	Required SW: [[BR]]
  o	Flukes [[BR]]
  o	Omni [[BR]]
  o	iRODS client [[BR]]
  o	Web browser [[BR]]
  o	EC [[BR]]

To Do:  [[BR]]
 •	Is there a way to pre-install all required credentials? [[BR]]
 •	What Java version does Flukes require? [[BR]]

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

To Do:  [[BR]]
 •	Pick a good application, or “reference experiment”  (6/1) [[BR]]
 •	Prepare a reference use case  (6/1) [[BR]]
