Speaker: Stephen Wolbers

  CDF will write data in Run 2 at twenty times the rate of Run 1. The offline production must be able to handle this rate. Components of that production include a large PC farm, I/O systems to read/write data to/from mass storage, and a system to split the reconstructed data into physics streams which are required for analysis. All of the components must work together as seamlessly as possible to ensure the necessary throughput.
  A description will be given of the overall hardware and software design for the system. A small prototype farm has been used for about one year to study performance, to test software designs and is used for the first Mock Data Challenge. Results from the tests will be shown and experience from the first Mock Data Challenge will be discussed. The hardware for the first production farm is in place and will be used for the second Mock Data Challenge. Finally, the possible scaling of the system to handle even larger rates foreseen later in Run 2 will be described.
