Notes from Meeting.
  • Notes from meeting of 13th June:
  • SKA:
    • It was noted that the SKA batch jobs are limited to 24 cores by the Dirac system (at Imperial) that they are using.
  • Dune/ProtoDune:
    • There is now a regular monday meeting for Dune/ProtoDune. Raja, as the Dune-Tier1 liaison person will attend regularly. Darren will attend in his place if Raja cannot be there.
