Poster Track 1: Computing Technology for Physics Research Poster Session


Roger Jones (Lancaster University (GB))


The LHC and other experiments are evolving their computing models to cope with the changing data volumes and rate, changing technologies in distributed computing and changing funding landscapes. The UK is reviewing the consequent network bandwidth provision required to meet the new models, there will be increasing consolidation of storage into fewer sites and increase use of caching and data streaming to exploit sites dominated by CPU capacity. While broad-brush arguments can be used to set the general scale of the bandwidths required, more detailed modelling and calculation is useful when convincing the providers of networking. An attempt to build a more detailed model based on ATLAS requirements in the UK will be presented.
