Abstract:
Data operations, requiring a lock, are batched into a set of operations to be performed on a per-core basis under a single lock. A Most Recently Used (MRU) listing is used to conduct a demotion scan using an MRU flush, a processor identification (ID), and a track change characteristic algorithm.
