PMem Repositories
Here is a list of all the repositories in the pmem organization in GitHub under https://github.com/pmem.
The Persistent Memory Development Kit is a collection of libraries and tools. The source is spread across many repositories. Components are separated like this to help with the logistics of parallel development and asynchronous delivery.
Components Focused on Persistence:
| Repo Name | Description | Microsite |
|---|---|---|
| pmdk | PMDK Core C libraries and tools:
| pmem.io/pmdk |
| valgrind | Enhanced Valgrind containing the pmemcheck plugin | pmem.io/valgrind |
| llpl | Low-Level Persistence Library for Java | pmem.io/java/llpl |
| libpmemobj-js | JavaScript bindings for libpmemobj | - |
| pmdk-tests | Extended PMDK tests | - |
Components Focused on Volatile Usages of pmem:
| Repo Name | Description | Microsite |
|---|---|---|
| memkind | General-purpose malloc/free-style library (Actually lives outside the pmem GitHub org since it has a life outside of pmem as well) | - |
Experimental PMDK components (not yet ready for production use):
| Repo Name | Description | Microsite |
|---|---|---|
| pcj | Persistent Collections for Java | - |
Other:
| Repo Name | Description | Microsite |
|---|---|---|
| dev-utils-kit | Tools used for development of projects under pmem organization | - |
| autoflushtest | Basic data integrity test for platforms with flush-on-fail CPU caches | - |
ndctl is the Linux utility for managing persistent memory.
| Repo Name | Description | Microsite |
|---|---|---|
| ndctl | ndctl, daxctl, and related libraries | pmem.io/ndctl |
The pmem.io website is implemented as static content on GitHub using Jekyll, GitHub-flavored MarkDown, and some tool-generated HTML here and there. Some sub-areas of the website live in the gh-pages branch of the corresponding repo (for example, pmdk and ndctl).
| Repo Name | Description | Microsite |
|---|---|---|
| docs | Persistent Memory Docbook | - |
| pmem.github.io | Repo containing the pmem.io website (including blogs) | - |
| pmdk-examples | PMDK examples and tutorials | - |
| book | Examples used in the pmem Programming Book | - |
These repos contain experimental versions of software modified to leverage persistent memory. Typically, when the features are mature and tested they become part of the upstream repo.
| Repo Name | Description | Microsite |
|---|---|---|
| pelikan | Working tree for development of pmem-related features for Twitter's Pelikan | - |
| pmem-rocksdb | RocksDB modified to use pmem | - |
| pmem-redis | Redis, enhanced to use pmem | - |
| pmse | MongoDB pmem Storage Engine Prototype | - |
| kvdk | Reference code of key/value store design for pmem | - |
These repos are no longer under active development or use. We archive them here for reference.
