CMS report
1) Rethink Ticket system
2) Survey on NAF usage
- more memory intensive applications
- columnar analysis
- Production of custom NanoAOD are using CMS grid, not the NAF.
3) Ideas:
- monthly NUC meetings again
- Feedback
- Change in usage pattern
- e.g. less production like slimming/slimming of official data sets
General discussion
