Minutes and actions from DOMA Access meeting (from 12 February : https://indico.cern.ch/event/769500/)

- Status of xcache 

  o Issue on proxy delegation for xcache : Not short term
  o Need to set up organisation to agree on requests prioritisation of xrootd : To be followed (HSF?) 

- Xcache operation in CMS and ATLAS

  o  Use case : Can xcache help to share data among distant analysis sites ? (to be kept in mind)
  o Debate on the long distant access efficiency with xrootd : Effect to be quantified (to be followed in US ?)
  o Issues or limitations in xcache reported by Ilija. To be followed with Xrootd expert. Current problems might require 
fine tuning of config parameters per xcache instance. The proposition is to manage xcache centrally as in the US or as for Munich. But how can 
it scale to hundred sites ? 

Presentation on the german experience of xcache in ATLAS-Germany postponed
Presentation on 'Scheduling with Virtual Placement DDM' postponed

Next meeting on 12 March
