Abstract
Methods and systems for providing cache coherence in multi-compute-engine systems are described herein. In on example, concise cache coherency directory (CDir) for providing cache coherence in the multi-compute-engine systems is described. The CDir comprises a common pattern aggregated entry for one or more cache lines from amongst a plurality of cache lines of a shared memory. The one or more cache lines that correspond to the common pattern aggregated entry are associated with a common sharing pattern from amongst a predetermined number of sharing patterns that repeat most frequently in the region.
