To Run on the core cluster: Make sure you have access to ui.core.wits.ac.za:

1. Scott Hazelhurst has hopefully created an account for you which will allow you to access cream-ce.core.wits.ac.za, and ui.core.wits.ac.za
2. on your local machine open a terminal and run 'ssh-keygen -t dsa' (an empty passphrase is suggested)
3. add the contents of ~/.ssh/id_dsa.pub to ~/.ssh/authorized_keys on cream-ce.core.wits.ac.za
4. logging in from your local machine should now not require a password, and you will be able to login to ui.core.wits.ac.za
5. Log in to ui.core.wits.ac.za
6. 1. add the following to ~/.bashrc
      alias asetup='source $VO_ATLAS_SW_DIR/software/<version>/setup.sh'
      source $VO_ATLAS_SW_DIR/ddm/latest/setup.sh
      export LC_ALL=C
   2. where <version> (which must be 16.0.0 or later) is the ATLAS release to be set up (available from 'ls $VO_ATLAS_SW_DIR/software/')
   3. a list of everything installed at WITS is available from this page: https://atlas-install.roma1.infn.it/atlas_install/list.php?sitename=ZA-WITS-CORE
   4. asetup <version> (where version is any installed version, even before 16.0.0) will set up that version for you
   5. For more details and configuration options refer to:
      1. The ATLAS computing tutorial
      2. The AtlasSetup page
7. you would need to source $VO_ATLAS_SW_DIR/local/setup.sh (if available) after you set up the release, to use Frontier and the conditions
8. In order to use DQ2Utils:
   1. export DQ2_LOCAL_SITE_ID=ROAMING (for bash)
   2. source /opt/exp_soft/atlas/ddm/latest/setup.sh
   3. remember to do a 'voms-proxy-init --voms atlas'
9. I suggest just adding the following to your .bashrc / .tcshrc
   • export DQ2_LOCAL_SITE_ID=ROAMING (for bash)
   • source /opt/exp_soft/atlas/ddm/latest/setup.sh
