Home Page for the LHCb - LNF cluster configuration

Machines

There are 19 machines currently available

1. lhcbui1
2. lhcbui3
3. lhcb-ui{01-02,04-18}

The machines lhcbgpfs01, lhcbgpfs02 and lhcb-ui03 are used as servers and should not be used for analysis/interactive use.

Access

To access the machines

ssh <nomemacchina>

from the lxgw node. A proposal for the use of the machines is the following:

Machine	Main User
02	asarti
04	Barbara
05	Flavio
06	Matteo P.
07	Matteo R.
08	Marco
09	Patrizia
10	R. Vazquez Gomez.

Other machines should be left for "massive/intesive" usage (tuple production/fit running) and the access/usage has to be coordinated with Matteo.

Software

LHCb software

To have access to the lhcb software

first of all you need to:

• Add the following lines to your .bashrc file in your home

export X509_CERT_DIR=/cvmfs/lhcb.cern.ch/etc/grid-security/certificates
export X509_VOMS_DIR=/cvmfs/lhcb.cern.ch/etc/grid-security/vomsdir

• Then you need to

source /data/software/LbLogin.sh

Then you'll have all the LHCb software available through the SetupProject * commands.

Other software

• sl6
• cvmfs
• latest compilers under devtools2 distro
• afs

If you do not want to use the root shipped using cvmfs you can use a local version of root:

adding to your .bashrc

source /opt/rh/devtoolset-2/enable

followed by

export ROOTSYS=/data/software/root_60302
export LD_LIBRARY_PATH=$ROOTSYS/lib
export PATH=$PATH:$ROOTSYS/bin
