[edit] How to setup your Desktop / Laptop to use ATLASLocalRootBase

Useful Information:

• Please check this Updates page on a regular basis to see what software is available or removed.

ATLASLocalRootBase is an nfs mount that is available to ATLAS users within the triumf.ca domain. This filesystem contains centrally managed Athena, gLite, DQ2, Ganga and other software that you may need for your analysis.

The steps to make this available on your computer is to configure your mount as follows: As a normal user, do

• cvs -d:pserver:anonymous@cvs.atlas-canada.ca:/atlas/cvs/cvs/atlasCanada checkout tier3Triumf/localSetup
• and follow the instructions in tier3Triumf/localSetup/auto.atlas_README

(Currently only atlas-tier3.triumf.ca is available for mounting.) You will need root privileges to do the installation as described.

As a normal user, to access the filesystem which is available on /atlas/ATLASLocalRootBase,

• export ATLAS_LOCAL_ROOT_BASE=/atlas/ATLASLocalRootBase
• source ${ATLAS_LOCAL_ROOT_BASE}/user/atlasLocalSetup.sh

(or the equivalent c-shell variants; also, atlasLocalSetup.sh --help will show the available options.) This will setup various aliases for packages which you then invoke to use.

Tip: you can also add this in ~/.bashrc and simply type setupATLAS when needed.

 export ATLAS_LOCAL_ROOT_BASE=/atlas/ATLASLocalRootBase 
  
 alias setupATLAS='source ${ATLAS_LOCAL_ROOT_BASE}/user/atlasLocalSetup.sh' 

Note that there are example requirements and gangarc files in $ATLAS_LOCAL_ROOT_BASE/user which you can copy and use. You can find more information on what the above commands do on this Canada Twiki page.
