Workflow jobs
  • Local
  • MPI, GPU, ATLAS offline, Minerva, tutorials
  • Grid EELA
  • prod.vo.eu-eela.eu (GAMOS etc.)
  • oper.vo.eu-eela.eu (obsolete)
  • Grid EGEE/WLCG
  • ATLAS, NA61 (?)
  • DTEAM, OPS

Conclusions and Outlook
  • Lesson 1 team work!
  • Lesson 2 network (bandwidth, firewall etc.)
  • Upgrades hardware, software, network.
  • Storage up to 100TB and more!
  • New services (WNS, LB etc.) for NGI.
  • Grid or Cloud?

Cooperative!
