Memory consistency and coherency

WebConsistency definitions provide rules about loads and stores (or memory reads and writes) and how they act upon memory. As part of supporting a memory consistency model, many machines also provide cache coherence protocols that ensure that multiple cached copies of data are kept up-to-date.

Consistency: The issue of when a written value MUST be seen by a reader is defined by a memory consistency model. For now, let's assume that a write is not complete until all processors have "seen" the effect of the write. Also, assume that a processor may not reorder memory accesses to move reads before an outstanding write. familysearch merge duplicatesWebManycore systems support cache-coherency mechanisms (see Section 2.2) for maintaining a consistent view of shared-memory in multilevel cache-memory architectures. However, imposing cache-coherency alone does not guarantee complete memory consistency that insures correctness and predictability of the running results of a multithread application. cool lens flare
