A. Establish Environment

A.1 Establish experiment managment (user workspace) service

  • 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!!

A.2 Gather necessary keys, certificates and credentials

For the specific case of this tutorial all necessary keys, certificates and credentials have already been set up and configured for the tutorial accounts (gimi1-gimi30). http://groups.geni.net/geni/wiki/GENIUserWorkspace/ConfigCredentials Here you can find more detailed information on the credential management and configuration.

A.3 Verify availability of desired aggregates

MZ: For this tutorial I think that should be covered in part B.

A.4 Verify availability of desired software images/packages

MZ: List what's installed on the VM

A.5 Verify availability of necessary operational services, and access to those services

1) Establish experiment environment

1.1) Establish experiment managment (user workspace) service

1.2) Gather necessary keys, certificates and credentials

1.3) Verify availability of desired aggregates

1.4) Verify availability of desired software images/packages

1.5) Verify availability of necessary operational services, and access to those services
