## What it is
The Persistent Memory Development Kit (PMDK) is a collection of C libraries and tools (libpmem, libpmem2, libpmemobj, and others) for managing and accessing byte-addressable, non-volatile persistent memory devices. This original pmem/pmdk repository has been archived and the project has moved to daos-stack/pmdk.

## Use cases
- program applications that use persistent memory directly
- manage non-volatile DIMM devices from Linux
- build crash-consistent data structures in persistent memory
- emulate persistent memory with DRAM for development and testing
- access persistent memory at low level with libpmem
- use transactional object stores on persistent memory

## When to choose
- you are developing C/C++ applications targeting persistent memory hardware or emulated PMem on Linux
- you need stable, production-quality libraries for byte-addressable non-volatile memory programming
- you are maintaining an existing PMDK-based application

## When to avoid
- you need active maintenance or new features - this repository is archived and no longer maintained here
- you are not working with persistent memory hardware or emulation
- you need a portable solution across Windows or macOS - PMDK primarily targets Linux

## Facets
- artifact type: library
- maturity: abandoned
- function: file-system, caching, developer-tools
- domain: developer-tools, operating-systems, databases, performance
- platform: c, cpp
- tags: persistent-memory, pmem, nvm, non-volatile-memory, libpmem, byte-addressable-storage, intel-optane, nvdimm, archived, linux
