CCNU LHCb farm 2


The computers for LHCb are comput19-23. CVMFS is installed on these machines.



The simplest way to set up root is by running

source /home/lhcb/setups/

It will set up ROOT from LCG on CVMFS. Currently, the version of root in this script is 6.18.04 with python 3 support. One can also set up a different version in a similar way. For example, if one needs 6.18.00 with python 2, this command will do it:

source /cvmfs/


aspell is installed on comput19 and comput23

slurm jobs

An example script for batch job submission can be found in the attachment and this command could be used to submit jobs:
Note that the options are given inside the script.

Problems and solutions

Direct-access farm2 from hepfarm

We could use sshfs to mount part of the space in farm2 to hepfarm. This is not in place yet. We will only do this if it's considered useful.

  1. mount/unmout need root permission
  2. Need to set up a file to map the users
  3. If we want to set up this, we could use the lhcb account and just mount a subdirectory in its home
