Using the Valgrind Framework to Build a Persistent Memory Error Detector by Krzysztof Czurylo

Using the Valgrind Framework to Build a Persistent Memory Error Detector - Krzysztof Czurylo & Tomasz Kapela, Intel

Valgrind is a popular, multi-platform instrumentation framework for building dynamic binary analysis tools. In the Linux community, it is mostly known and valued for a few popular tools: Memcheck - a memory-management error detector, and Helgrind/DRD - two threading bugs detectors.
In this talk, we will present a new tool built on Valgrind - Pmemcheck - yet another memory error detector designed specifically to detect problems with Persistent Memory programming.
First, we will talk about the motivation for creating new error detector and the reasons for which we have chosen Valgrind framework to create Pmemecheck. We will also shed some light on typical issues related to the use of byte-addressable persistent memory. Finally, we will present an in-depth view on the Pmemcheck design and the changes we have made to the core part of Valgrind to support persistent memory.
