In this section there are various useful notes on ATLAS computing at Manchester.

ATLAS Software on Linux8

Various ATLAS release are installed on the linux8 cluster at Manchester, for use instructions, see ManAthenaInstallationsSLC5. new CVMFS can now be used to get the ATLAS software on tony - will be available on all machines soon - see ManAtlasCVMFS.

CERN cvs & svn Access on Linux8

General instructions for cern cvs access are here and for svn access are here. On linux8 you can use kerberos authentication to gain access to cvs or svn via ssh, simply do the following, replacing username with your username on lxplus:

kinit --no-afslog username@CERN.CH
The standard checkout commands should now work without a prompt for your password. Note that if your username on the linux8 cluster is different to your cern username, you will have to change the SVNROOT variable:
export SVNROOT="svn+ssh://"
where username should be your cern username. This needs to be done after setting up the atlas release (since setting up the release changes this variable).

Manchester has a group area within the ATLAS svn repository - you can see it's contents here.

If you need to access the manchester cvs repository at cern you need to do:

If your cern username is different to you linux8 one, then you will need:

Ganga & dq2

The latest version of ganga is installed on all the linux8 nodes (in /opt/ganga/install) & should already be in your PATH. To enable the atlas specific extensions, you just need to do:

export GANGA_CONFIG_PATH=/afs/
before running ganga. It is also possible to use the cern installation, to set it up do:
source /afs/

To use dq2 it is usually best to use the up-to-date installation at cern. To set up dq2 do:

source /afs/ py25
It is best to tell dq2 that you are in the UK, not cern, by doing:

You'll also need to get a proxy for your grid certificate like:

voms-proxy-init -voms atlas
