....lead to an improvement in performance of two orders of magnitude in some cases. Other more course grain approaches for improving locality in general SMP software include automated support for memory page placement, replication and migration [18, 23, 40] and cache a#nity aware process scheduling [39, 24, 13, 33, 9]. 1.2 SMP Operating Systems Poor performance of the operating system can have considerable impact on application performance. For example, for parallel workloads studied by Torrellas et al. the operating system accounted for as much as 32 47 of the non idle execution time[36] Similarly Xia ....
