Welcome to CMS Data Analysis School(s)

Basic Information

You are looking at this page because you have registered for the CMSDAS school. This page is used to provide instructions/links to computing setup for CMSDAS held outside CERN and FNAL.

BEFORE coming to the school, students must complete four sets of pre-exercises. The answer to these sets of pre-exercises must be given in the forms provided in the respective espace area (linked from pre-exercises twiki).These should have instructions on how to access and fill the form. These sets of exercises will help you in getting ready for the computing environment and CMS software and tools needed for the actual school. These exercises can also be done on lxplus at CERN at anytime before, during or after the school or at cmslpc.

During the 5 day school you would be doing SHORT and LONG exercises.
