Abstract

Disclosed herein are system, method, and computer program product embodiments for cache partitioning to accelerate concurrent workload performance of in-memory databases. An embodiment operates by storing a first bitmask, associating the first bitmask with a first processor core, setting a subset of the bits of the first bitmask, wherein the subset of the bits of the first bitmask represents a first portion of shared last-level cache, and wherein any part of the first bitmask excluding the subset of the bits of the first bitmask represents a second portion of the lowest-level cache, and disallowing eviction of any cache line in the second portion of the lowest-level cache by the first processor core.
