Everything starts here

The most common machines to run are lxplus.

ssh -Y lxplus.cern.ch -o ServerAliveInterval=240

Once logged in we need to set the architecture.

setenv SCRAM_ARCH slc6_amd64_gcc491

If not running from lxplus, the CMS environment has to be set.

source /cvmfs/cms.cern.ch/cmsset_default.csh

Now we can choose our favorite CMSSW release.

cmsrel CMSSW_7_4_1
cd CMSSW_7_4_1
cmsenv

It is time to get the material
