RAL Tier1 Operations Report for 11th February 2019
Review of Issues during the week 28th January 2019 to the 5th February 2019.
|
- CPU Efficiencies have improved for CMS (>80%), although it is still fluctuating a lot. ATLAS has still 60 - 70% efficiency, Atlas liaison has investigated, the fluctuations look like mostly a result of a different mix of types of jobs, especially failed jobs and group production, which have a lower efficiency. The overall efficiency is similar, maybe a bit better than this time last year.
