CernVM-FS – beyond LHC computing
Catalin Condurache, Ian Collier · Journal of Physics Conference Series · 2014
In the last three years the CernVM File System has transformed the distribution of experiment software to WLCG sites. CernVM-FS removes the need for local installations jobs and performant network fileservers at sites and it often improves performance at the same time. Now established and proven to work at scale, CernVM-FS is beginning to perform a similar role for non-LHC computing. The deployment of CernVM-FS service at RAL Tier-1 is presented, as well as the proposed development of a network of Stratum-0 and Stratum-1 replicas somewhat modelled upon the infrastructure developed to support the WLCG computing. A case study of one non-LHC Virtual Organization is also included, describing their use of the CernVM-FS Stratum-0 service, along with a web interface intended to be used as a tool to upload software at Stratum-0 sites.
