Access and exploitation of large scale computing resources, such as those offered by general
purpose HPC centres, is one import measure for ATLAS and the other Large Hadron Collider experiments
in order to meet the challenge posed by the full exploitation of the future data within the constraints of flat budgets.
We report on the effort moving the Swiss WLCG T2 computing,
serving ATLAS, CMS and LHCb, from a dedicated cluster to large CRAY systems
at the Swiss national supercomputing centre, CSCS. These systems do not only offer
very efficient hardware, cooling and highly competent operators, but also have large
backfill potentials due to size and multidisciplinary usage, and potential gains due to economy of scale.
Technical solutions, performance, expected return and future plans are discussed.
