In this paper, we run simulation experiments under localized core affinities limited to a very small number of specific cores within core classes. These localized schedules represent applications that are user- or system-confined to specific cores or their vicinity. They may also represent stressful scenarios with high contention to specific - and possibly scarce - cores with unique functionality or computational might. The results indicate that under these localized initial core affinity scenarios, non-migratory thread scheduling algorithms perform much worse than non-affinity algorithms while the algorithms which consider core affinity and allow inter-core thread migration are best.}, isbn = {978-1-4244-1841-1}, doi = {10.1109/IIT.2007.4430377}, keywords = {heterogeneous multicore os-scheduling } }
