дұрыс емес бөліну

дұрыс емес бөліну

A condition that occurs in cache when two unrelated data accessed independently by two threads reside in the same block. This block can end up 'ping-ponging' between caches for no valid reason. Recognizing such a case and rearranging the data structure to eliminate the false sharing greatly increases cache performance. See also cache, cache locality.
