Experiment Session

The goal of the session is to allow experiments to transmit information to sites and WLCG operations about the Run2 data taking. Examples of topics to cover are:
- Expected processing scales
- Recent and upcoming developments in the computing systems (within Run2)
- Operational procedures relevant to sites
- Other experiment requirements for sites and WLCG operations
