GIMI Instrumentation and Measurement Tool: Tutorial Instructions

Prerequisites

1. To prepare for the tutorial, each participant should install ​VirtualBox and the GENI User Workspace image on their computer. Instruction for this step can be found here: ​User Workspace

2. You should have attended the ​ExoGENI tutorial given right before the GIMI tutorial. (Ideally, you would also have attended the ​OMF/OML tutorial given at GEC14.

3. Besides OMF/OML and ExoGENI, this tutorial will make also use of ​iRODS and ​IREEL and the interested participant can find further information at the links given for both tools.

4. Account information for all tools will be handed out on paper to the participants at the beginning of the tutorial.

Common Errors

• Be careful cutting and pasting
  • Doesn’t work from Trac
  • Sometimes even txt file inserts hidden characters
  • Some lines require edits; don’t cut and paste the newline

• Make terminal windows big
  • Sometimes terminal gets corrupted when pasting a line that runs to the next line (especially when backspacing)

Getting Ready

• Bring up tutorial VM and log in.
• Open Firefox web browser
• Open a terminal window
• The software required for this tutorial is already installed in the tutorial VM.
• Download GIMI tutorial specific configuration files by issuing the following command in a user workspace terminal:

  $ cd ~/Tutorials/GIMI/common/
  $ git pull
  

• The iRODS client uses a configuration file (~/.irods/.irodsEnv) that sets certain parameter for the icommands. Here is and example:

  # iRODS personal configuration file.
  #
  # This file was automatically created during iRODS installation.
  #   Created Thu Feb 16 14:06:27 2012
  #
  # iRODS server host name:
  irodsHost 'emmy8.casa.umass.edu'
  # iRODS server port number:
  irodsPort 1247
  
  # Default storage resource name:
  irodsDefResource 'iRODSUmass'
  # Home directory in iRODS:
  irodsHome '/geniRenci/home/gimiXX'
  # Current directory in iRODS:
  irodsCwd '/geniRenci/home/gimiXX'
  # Account name:
  irodsUserName 'gimiXX'
  # Zone:
  irodsZone 'geniRenci'
  

• First of all copy the template iRODS configuration file to .irodsEnv with the following command:

  $ cp ~/.irods/gimiIrodsEnv ~/.irods/.irodsEnv
  

• Open ~/.irods/.irodsEnv with your favorite text editor (we recommend nano) and change gimiXX to your assigned username (e.g., gimi04).
• Register with iRODS server by issuing the following command (more details on iRODS will be given shortly):

  $ iinit
  

• You will be prompted for a password. Please type in the password you were provided with on the paper handout!!
