    Abstract:

    This paper describes the early experiences with the large IBM p690+ systems at ECMWF. Results are presented for the IFS (Integrated Forecasting System) which has been parallelized with MPI message passing and OpenMP to obtain good scalability on large numbers of processors. A new profiler called Dr.Hook, which has been developed to give detailed performance information for IFS, is described. Finally the code optimizations for IFS on the IBM p690+ are briefly outlined.
