Software

Common software like “ROOT” , mathematica,….Are installed in each desktop, node,….

Use the following to find the path if you need it

which root/opt/root/bin/rootwhich mathematica/usr/site/mathematica/5.0/Executables/mathematica


Software

Each experiment have a software are in partition“G”/afs/hep.man.ac.uk/g

[root@afs5 root]# ls /afs/hep.man.ac.uk/g accelerators babar calice grid kickstart atlas bfactory dzero hepbackup nemo sw[root@afs5 root]#
