Add to ORKGWe describe our experiences in repeated cycles of performance optimization, benchmarking, and performance analysis of the Parallel Ocean Program (POP) on the Cray X1 at Oak Ridge National Laboratory. We discuss the implementation and performance impact of Co-Array Fortran replacements for communication latency-sensitive routines. We also discuss the performance evolution of the system software from May 2003 to May 2004, and the impact that this had on POP performance.
