After this, Brian and I walked to the Users' Center to create my account. Then, we walked to the ID badge place to get my CERN ID. At this time, it was raining.
After getting my ID, we walked to meeting building, which happened to be on the other side of CERN (I walked across the Swiss/French border, can't even tell).
Listened to 3 talks. The first two where very CMS and physics heavy. I didn't understand much. Ian gave a talk about the future challenges in CMS computing. Punchlines where:
- Redesigning the CAF (CERN Analysis Farm) to have better data access (integrate Xrootd redirector)
- We're running out of Cycles at CMS T1's
- CMS reduced the AOD (Analysis-Oriented Data) copies. More transfers between sites rather than strict adherence to tree, trickle down, theory.
A few physics talks that I didn't quite grasp. Geant4 talk. Fast simulation talk.
Learned a lot about the CMS Production workflow.
- Seems odd that they have to warn sites what files they will run on, shouldn't we be running better technology? This sounds like an issue with dCache? Do they do this on Hadoop Clusters? Lustre?
- Didn't mention if these production jobs run outside the T1's. I certainly see something from CMS Production at Nebraska.
After the talk, we went to the 'CMS Drink' at a building right next to our Hostel (though it was a walk from where the meetings where held). This was just an horderve and wine event. I forgot how much I didn't like red wine. But the white wine was tolerable.
During the 'Drink' session, a few of the people that Brian knows planned dinner at a local chicken place, Chez Ma Cousine.
And a few people outside of the entrance after eating.
