Title: Revisiting "Multiprocessors Should Support Simple Memory Consistency Models" Mark D. Hill Univ. of Wisconsin-Madison Abstract: Five years ago I published "Multiprocessors Should Support Simple Memory Consistency Models" [IEEE Computer, August 1998]. It discussed the memory consistency model interface between low-level software and hardware (as a opposed to a high-level language (HLL) interface). It argued that the low-level interface should be sequential consistency (or possibly processor consistency), regardless of the HLL interface. In this talk, I will revisit my arguments five years on.
