Conditions data access and related services
- Frontier/Squid
- The minutes of the last meeting can be found at the usual URL:ATLAS weekly FroNTier meetings
- Release 2.7.STABLE9-3 of frontier-squid has been announced. The release notes can be found here. The relative rpm has been made available for tests on Tuesday this week. Feedback received from BNL and CMS and integrated. A new rpm release will be announced soon.
- Squid caches are needed at CERN to alleviate stress on launchpads at other sites (namely Lyon). Information requested about the number of batch slots allocated to ATLAS and CMS analysis jobs since the number of needed squid caches depends on the number of slots. Squid caches at CERN will be installed for ATLAS by the VOC as soon as this information and the new rpm will be available.
- Squid caches can be installed on VMs provided that the physical machine hosting the VMs comes with multi-Gigabit network connectivity (1Gb/sec-link per Squid).
- Dave Dykstra requested more resources to monitor Squid and Frontier launchpad in ATLAS. The request is being put forward by the ATLAS VOC.
- Squid caches information will be stored in the ATLAS AGIS. Details on how to extract information from AGIS will be made public by the AGIS developers.
- CNAF have asked if they should install a frontier server for ATLAS or just squid caches. The recommendation is to install squid caches. CNAF has already 2 squid caches for CMS installed. They can share them with ATLAS if the total number of job slots for the 2 experiments does not exceed 1000.
