To make the required development work easier, Intel developed and open sourced
the Persistent Memory Development Kit (PMDK) available from https://pmem.io/
pmdk/. We introduce the PMDK in more detail in Chapter 5 and walk through most of
the available libraries in subsequent chapters. Each chapter provides an in-depth guide
so developers can understand what library or libraries to use. PMDK is a set of open
source libraries and tools based on the Storage Networking Industry Association (SNIA)
NVM programming model designed and implemented by over 50 industry partners. The
latest NVM programming model document can be found at https://www.snia.org/
tech_activities/standards/curr_standards/npm. The model describes how software
can utilize persistent memory features and enables designers to develop APIs that take
advantage of NVM features and performance.
Available for both Linux and Windows, PMDK facilitates persistent memory
programming adoption with higher-level language support. C and C++ support is fully
validated. Support for other languages such as Java and Python is work in progress
at the time this book was written. Other languages are expected to also adopt the
programming model and provide native persistent memory APIs for developers. The
PMDK development team welcomes and encourages new contributions to core code,
new language bindings, or new storage engines for the persistent memory key-value
store called pmemkv.
This book assumes no prior knowledge of persistent memory hardware devices
or software development. The book layout allows you to freely navigate the content in
the order you want. It is not required to read all chapters in order, though we do build
upon concepts and knowledge described in previous chapters. In such cases, we make
backward and forward references to relevant chapters and sections so you can learn or
refresh your memory.
Book Structure
This book has 19 chapters, each one focusing on a different topic. The book has three
main sections. Chapters 1-4 provide an introduction to persistent memory architecture,
hardware, and operating system support. Chapters 5-16 allow developers to understand
the PMDK libraries and how to use them in applications. Finally, Chapters 17-19 provide
information on advanced topics such as RAS and replication of data using RDMA.
