Bristol-CMS-PHYS14

soolin

soolin is both a condor submission machine as well as testing ground for software development. It comes with Scientific Linux (6.6):

cat /etc/redhat-release 
Scientific Linux release 6.6 (Carbon)

updated GCC (4.8.2)

scl enable devtoolset-2 bash
gcc --version

It has the following hardware:

• 2 x Intel(R) Xeon(R) CPU E5405 @ 2.00GHz
• 16 GB of RAM (DIMM DDR2 667 MHz (1.5 ns))
• around 4.1 TB of non-backed up file storage (on mount /storage)

It has also access to both our GPFS (/gpfs_phys) and HDFS (/hdfs) storage

software

soolin comes with CVMFS, which means that software for the ATLAS, ALICE, CMS, ILC and LHCb experiments is available under (/cvmfs). Since it is an automount the folder you are looking for (e.g. /cvmfs/cms.cern.ch) might be not mounted. Just try to access it and it will appear. Furthermore custom software compilations are available under /software

ROOT (compiling ROOT on soolin)

scl enable devtoolset-2 bash
# get ROOT source
# select git tag you want
git tag -l
git checkout v5-34-25
./configure --enable-roofit --enable-minuit2 --enable-builtin-freetype
make jobs=4

CMSSW (latest)

In order to enable the CMSSW commands first source

. /cvmfs/cms.cern.ch/cmsset_default.sh

and set SCRAM_ARCH

# this refers to the slc* folders in /cvmfs/cms.cern.ch
export SCRAM_ARCH=slc6_amd64_gcc491

You can get a list of available version by doing

scram list CMSSW

Pick the one you want (latest CMSSW_7_4_0_pre6_ROOT6 and CMSSW_7_4_0_pre6 [ROOT 5.34.X]) and get it:

cmsrel CMSSW_7_4_0_pre6_ROOT6
cd CMSSW_7_4_0_pre6_ROOT6/src
# enable CMS environment
cmsenv
# put your code here and use your usual build methods

An example of such a setup can be found here: https://github.com/BristolTopGroup/AnalysisSoftware/

Additional CMSSW tools can be enabled using the scram setup <tool> command. For a full list of available tools:
