Usage of the Milano-Bicocca Hercules cluster

get an account

usually an account is made for any student and researcher at the moment of registration
if you do not have an account, ask Paolo Dini for one, and if you're a student ask your supervisor to provide you with her/his request approval

the access server is named hercules.mib.infn.it
the server is not accessible from outside the INFN Milano-Bicocca network, therefore one should first connect to cerbero, and then from there to hercules:

ssh username@cerbero.mib.infn.it
ssh username@hercules.mib.infn.it

Run the following commands from within hercules (better save them in bash or setup script)

export KRB5CCNAME=/gwpool/users/<hercules_username>/krb5cc_`id -u <hercules_username>`
kinit
eosfusebind -g
aklog

If your hercules username does not match you lxplus username:

export KRB5CCNAME=/gwpool/users/<hercules_username>/krb5cc_`id -u <hercules_username>`
kinit -f <lxplus_username>@CERN.CH
eosfusebind -g
aklog

Latinos won't work out of the box. A branch was made to let latinos work on hercules: https://github.com/UniMiBAnalyses/LatinoAnalysis/tree/VBS_skim_giacomo

Details are in the README of the VBS_skim_giacomo branch.
