VO specific software on the Grid

Accessing software distributed via CVMFS

For most VOs the software is now being distributed via CVMFS. The only detail a user (client) has to know is how the repository(-ries) are mapped on Worker Nodes. In this article we will use the gridpp VO repository, which is mapped to /cvmfs/gridpp.egi.eu/ . A VO software administrator uploaded a following example code into a directory called testing/ :

#!/usr/bin/env python
import sys

print "----------------------"
print "Hello, I'm a snake !  /\/\/o"
print "----------------------"

print " More info:\n"

print (sys.version)
