Abstract:
One of the significant trends of recent years has been the move towards multicore CPU's with ever increasing numbers of cores. CMS has been preparing multicore aware applications that rely on "multi-processing", namely the sharing of memory between processes forked from a single parent process. First experience with deploying these applications for production will be presented, as well as results from detailed profiling done to understand the limits of scaling with increasing numbers of cores.
