In this chapter, we introduce enough about cache coherence to understand how consistency models interact with caches. We start in Section 2.1 by presenting the system model that we consider through...

1.2 COHERENCE (A.K.A., CACHE COHERENCE) Unless care is taken, a coherence problem can arise if multiple actors (e.g., multiple cores) have access to multiple copies of a datum (e.g., in multiple c...

This chapter delves into memory consistency models (a.k.a. memory models) that define the behavior of shared memory systems for programmers and implementors. These models define correctness so that...
