Improving the Effectiveness of U.S. Climate Modeling
IFS, MC2, MM5, and LM/GME (A more detailed description of each code is provided in Appendix I). Each code has a best microprocessor and vector performance achieved for both serial and parallel execution. We then compare them using the ratio of the sustained performance per processor between vector and microprocessor machines for both serial and parallel execution. The implications of the different performance characteristics will be explored in the following sections.
