13:30 Experiment Operational Issues

1 VO-Liaison ATLAS

Meeting notes ATLAS liason

2 VO Liaison CMS

Speaker: Katy Ellis (Science and Technology Facilities Council STFC (GB))

Katy is attending the all-afternoon Open Technical Forum.

SAM tests look good.

CMS still low on Production jobs, so running large numbers of User Analysis at times. This is having an effect on job performance, particularly low efficiency at times.

Ask Tom Birkett how the tokens on CEs is going - significant progress I believe.

Mini-DC will be discussed at Technical meeting, usual time this Friday.
