Abstract

Persistent Memory programming has well known challenges around cache flushing and the SNIA programming model includes the possibility of platforms where the CPU caches are considered persistent and need no flushing. On these platforms, operations like compare-and-swap and some non-blocking algorithms are easier to implement, but there are still some differences from volatile memory programming that the programming must understand. In this talk, Andy will describe how such platforms are created, the programming considerations, and the performance improvements that result.

Learning Objectives
