Introduction

Running the Athena software at a standalone site is slightly different from running at CERN. The main reason for this is that at a standalone site it is assumed that only the kit built releases are available. For most users the kit built releases are sufficient (these are all the standard releases which should be automatically distributed to all Tier 2s). A list of releases installed at each site can be found here (Select UKI-SOUTHGRID-RALPP from the site name to see whats installed at RAL. However even if the kit release is not installed at RAL (for example if you wish to work on a nightly release) you can still do this from RAL.

Setting up Athena

The full instructions to set up Athena can be found at WorkBookSetAccount. Quick instructions are given here: First log into one of the Linux machines.

As a standalone site

This is slightly different from at CERN. Each release that you install will have its own requirements files. It does not matter where you have your cmthome directory so you can place it inside the folder you install the release in. Tim Adye has written some scripts that will do this automatically https://twiki.cern.ch/twiki/bin/view/AtlasSandbox/TimAdyeReleaseScripts .

As CERN

> cd $HOME
> mkdir cmthome
> mkdir testarea
> mkdir testarea/15.3.0    (this is the directory in which you will work)
> cd cmthome

In order to be able to setup Athena following the link you need to know The Athena releases are stored at
