摘要：
Software, systems and methods are described which provide cache management capabilities. The number of cache sets to be used in each partition of the cache memory space is based on a number of cache pages in each partition and an associativity level associated with the set associative cache. The cache sets can be numbered based on the partition number, a total number of partitions and a cache page index. Cache management according to these exemplary embodiments reduces problems associated with cache trashing in multiprocessor environments sharing common data structures in set associative caches.
