Abstract
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.
