....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 ....

....the processing resource might be overloaded. But in EFQ this should never happen. Other possibilities of combining EFQ and LAP are considered as future work. Cache a#nity scheduling, which uses locality information for the scheduling decision has been used mostly in shared memory multiprocessors [VZ91] DM92] SL93] TTG95] The focus in this domain is to schedule the same process or thread on 110 processors that can reuse previously established cache state. While this is similar to the network processor environment, it does not consider the reuse of instruction cache state for di#erent ....
