Description
Performance of an experiment's simulation, reconstruction and analysis
software is of critical importance to physics competitiveness and making
optimum use of the available budget. In the last 18 months the performance
improvement program in the CMS experiment has produced more than a ten-fold
gain in reconstruction performance alone, a significant reduction in mass
storage system load, a reduction in memory consumption and a variety
of other gains. We present our application performance analysis methods
and our techniques for higher performance memory management, I/O, data
persistency, software packaging, code generation, as well as how to
reduce total memory usage. We report on specific gains achieved and the
main contributing causes. We discuss our estimate of future achievable
gains and promising new tools and analysis methods.
