CA 2666029

Testing real page number bits in a cache directory is provided. A specification of a cache to be tested is retrieved in order to test the real page number bits of the cache directory associated with the cache. A range within a real page number address of the cache directory is identified for performing page allocations using the specification of the cache. A random value x is generated that identifies a portion of the real page number bits to be tested. A first random value y is generated that identifies a first congruence class from a set of congruence classes within the portion of the cache to be tested. Responsive to the first congruence class failing to be allocated a predetermined number of times, one page size of memory for the first congruence class is allocated and a first allocation value is incremented by a value of 1.
