Analysis of sched_mc_power_savings

2008-01-08 Thread Vaidyanathan Srinivasan
Hi, The following experiments were conducted on a two socket dual core intel processor based machine in order to understand the impact of sched_mc_power_savings scheduler heuristics. Kernel linux-2.6.24-rc6: CONFIG_SCHED_SMT=y CONFIG_SCHED_MC=y CONFIG_TICK_ONESHOT=y CONFIG_NO_HZ=y CONFIG_HIGH_RE
