- 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.
- Access to the Tier1 batch farm is being set-up. The Tier1's aim is to get this set-up for initial testing by next Monday's meeting. (18th June).
- Alastair has set-up Dune access to Echo (line for access via WebDAV provided to Raja).
- Euclid:
- We are in contact with Euclid to get the public key for access to the Euclid CVMFS repository.
Documentation to Get VOs started accessing Tier1 Services:
