Persistent Memory Developer Hub

Learn, build, and deploy persistent memory features in your application using an extensive collection of resources, examples, structured tutorials, webinars, forums, and API documentation.

The PMDK repository on GitHub is the ultimate source of information on PMDK from release 2.0! For all questions and to submit eventual issues please follow to that repository. The PMDK documentation collected here should be valid up to the 1.13.1 release but is maintained only on a best-effort basis and may not reflect the latest state of the art.

Build with Persistent Memory

Utilize the extensive array of libraries available from low-level to highly abstracted across a broad set of programming languages.

Master Persistent Memory Programming

Whether you’re beginning your learning journey about persistent memory or you want to dive deeper into the programming details, Programming Persistent Memory is a great resource that with information for everyone. The book is available in English, Simplified Chinese, and Korean languages.

For Developers

Persistent Memory Key-Value Store (PMemKV)

pmemkv is a local/embedded key-value datastore optimized for persistent memory that provides options for language bindings and pluggable storage engines.

Low-Level Persistence Library for Java (LLPL)

The Low-Level Persistence Library (LLPL) is a Java library that provides access to off- heap persistent memory. LLPL includes several kinds of components that can be allocated and used in building applications.

Persistent Collections for Java (PCJ)

PCJ is a library for Java objects stored in persistent memory. Persistent collections are emphasized because many applications for persistent memory map well for collections.

Developer tools

A wide range of tools are available that allow you to inspect, analyze, debug, and collect performance data of the platform and application(s).

daxctl

Manage and monitor direct access (DAX) devices backed by persistent memory. Create, destroy, and convert dax devices for use with the Linux Kernel and applications.

Admin
daxio

daxio is a standalone utility that can transfer data to or from DAX devices, or erase data from a device.

Admin
Intel® Inspector

This tool finds persistence errors quickly to make software fast and reliable. It checks that all caches only flush once to persistent memory and written in the correct order.

Debug, Analysis
ipmctl

ipmctl is an open source utility to discover, configure, and manage Intel® Optane™ persistent memory modules. ipmctl, works on both Linux and Windows.

Admin, Hardware
ndctl

Manage and monitor non-volatile memory devices in Linux. Create and manage dimms, regions, and namespaces, update firmware, perform secure erase operations, and much more!

Admin
pmemcheck

Perform a dynamic runtime analysis with an enhanced version of Valgrind.

Admin, Debug
Intel® VTune Platform Profiler

Use the Platform Profiler for Intel® VTune™ Profiler to view performance metrics and learn how your application can benefit from large capacity persistent or volatile memory.

Performance, Debug, Analysis
Intel® VTune Profiler

Profile application memory accesses to identify code and code paths that are sensitive to memory bandwidth and latency issues. Identify hot, warm, or cool data to optimize memory usage and placement.

Performance, Debug, Analysis
Linux Perf|eBPF

perf and eBPF are performance analyzing, tracing, and profiling tools in Linux for hardware, the Kernel, and applications.

Performance, Debug, Analysis
FIO

Use the open-source Flexible I/O Tester (FIO) utility to run benchmarks against persistent memory devices and file systems.

Benchmark
Processor Counter Monitor (PCM)

Processor Counter Monitor (PCM) is an API and a set of tools to monitor the performance and energy metrics of Intel® CPUs. PCM runs on Linux and Windows. pcm-memory monitors memory bandwidth per channel and per DIMM for DDR and persistent memory.

Performance, Monitoring
pmdk-convert

The pmdk-convert tool converts the specified memory pool from an old layout version to the newest one supported by this tool.

Admin
pmembench

Run benchmarks using libraries from the Persistent Memory Development Kit.

Benchmark
pmemkv-bench

Benchmark for pmemkv and its underlying libraries, based on LevelDB’s db_bench.

Benchmark
pmempool

Manage, analyze, troubleshoot, and debug persistent memory pools with this utility.

Admin
pmreorder

The pmreorder is a utility that performs a consistency check of a persistent program.

Admin, Debug
Valgrind

Valgrind is an instrumentation framework for building dynamic analysis tools. Valgrind tools can automatically detect many memory management and threading bugs and profile your programs in detail. Use the pmemcheck utility with persistent memory.
