Software Implications of Persistent Memory and Architectural Support

This presentation will talk about software implications of persistent memory, highlighting two software implications/problems: 1) the read-of-not-yet-persisted-write problem for concurrent programs, and the architectural proposal to get that fixed with persistent atomics, and 2) the implications of persistent memory on sequential programs running on weak memory models such as Arm’s.
