The Appendixes have separate procedures for installing the PMDK and utilities
required for managing persistent memory. We also included an update for Java and the
future of the RDMA protocols. All of this content is considered temporal, so we did not
want to include it in the main body of the book.
Intended Audience
This book has been written for experienced application developers in mind. We
intend the content to be useful to a wider readership such as system administrators
and architects, students, lecturers, and academic research fellows to name but a few.
System designers, kernel developers, and anyone with a vested or passing interest in this
emerging technology will find something useful within this book.
Every reader will learn what persistent memory is, how it works, and how operating
systems and applications can utilize it. Provisioning and managing persistent memory
are vendor specific, so we include some resources in the Appendix sections to avoid
overcomplicating the main chapter content.
Application developers will learn, by example, how to integrate persistent memory
in to existing or new applications. We use examples extensively throughout this book
using a variety of libraries available within the Persistent Memory Development Kit
(PMDK). Example code is provided in a variety of programming languages such as C,
C++, JavaScript, and others. We want developers to feel comfortable using these libraries
in their own projects. The book provides extensive links to resources where you can find
help and information.
System administrators and architects of Cloud, high-performance computing,
and enterprise environments can use most of the content of this book to
understand persistent memory features and benefits to support applications and
developers. Imagine being able to deploy more virtual machines per physical server or
provide applications with this new memory/storage tier such that they can keep more
data closer to the CPU or restart in a fraction of the time they could before while keeping
a warm cache of data.
Students, lecturers, and academic research fellows will also benefit from many
chapters within this book. Computer science classes can learn about the hardware,
operating system features, and programming techniques. Lecturers are free use the
content in student classes or to form the basis of research projects such as new persistent
memory file systems, algorithms, or caching implementations.
