TagLib is a C++ library for reading and editing the meta-data of several popular audio formats. Currently it supports both ID3v1 and ID3v2 for MP3 files, Ogg Vorbis comments and ID3 tags and Vorbis comments in FLAC, MPC, Speex, WavPack TrueAudio, WAV, AIFF, MP4 and ASF files.

This library supports decoding of the Musepack (MPC) audio compression format.

Libmpg123 is a MPEG 1.0/2.0/2.5 audio decoder library for layers 1, 2 and 3 (MPEG 1.0 layer 3 aka MP3 most commonly tested).

Libout123 is focused on continuous playback of audio streams via various platform-specific output methods. It glosses over details of the native APIs to give an interface close to simply writing data to a file. The focus of the library is to ease the use case of just getting raw audio data out there, without interruptions.

mpDris2 is a client for the Music Player Daemon providing MPRIS 2 support.

Python-mpd2 is a Python library which provides a client interface for the Music Player Daemon.

ashuffle is an application for automatically shuffling your MPD library in a similar way to many other music players' 'shuffle library' feature. ashuffle works like any other MPD client, and can be used alongside other MPD frontends.

Cantata is a graphical client for the Music Player Daemon (MPD). Its user interface is highly customizable, supporting multiple collections, ratings, and dynamic playlists. A local cache of the music library will be created to provide a hierarchy of albums and artists along with albumart.

mpdevil is a music browser for the Music Player Daemon (MPD), which is focused on playing local music without the need of managing playlists. Instead of maintaining a client side database of your music library, mpdevil loads all tags and covers on demand.

MyMPD is a mobile-friendly web client for the Music Player Daemon (MPD).

Ncmpcpp is an mpd client with a UI very similar to ncmpc, but it provides new useful features such as support for regular expressions for library searches, extended song format, items filtering, the ability to sort playlists, and a local file system browser.

mpdscribble is a Music Player Daemon client which submits information about tracks being played to a scrobbler, such as Libre.FM.

Sonata is an elegant graphical client for the Music Player Daemon (MPD). It supports playlists, multiple profiles (connecting to different MPD servers, search and multimedia key support.

A stable, documented, asynchronous API library for interfacing MPD in the C, C++ & Objective C languages.

Music Player Daemon (MPD) is a flexible, powerful, server-side application for playing music. Through plugins and libraries it can play a variety of sound files while being controlled by its network protocol.

MPC is a minimalist command line interface to MPD, the music player daemon.

ncmpc is a fully featured MPD client, which runs in a terminal using ncurses.

rmpc is a terminal based Music Player Daemon client heavily inspired by ncmpcpp and ranger/lf file managers. It has support for synchronized lyrics, and displaying album cover art with various terminal image protocols.

A lightweight implementation of MPD to D-Bus bridge, which exposes MPD player and playlist information onto MPRIS2 interface so other programs can use this generic interface to retrieve MPD's playback state.

Distinctively, mpdris2-rs uses MPD protocol's native readpicture/albumart methods to fetch album arts. This means mpdris2-rs won't need any access to your local filesystem (apart from your XDG_RUNTIME_DIR for temporarily storing fetched albumarts) and can provide album arts even with remote MPD servers and Internet radios.

mcg (CoverGrid) is a client for the Music Player Daemon (MPD), focusing on albums instead of single tracks. It is not intended to be a replacement for your favorite MPD client but an addition to get a better album-experience.

The Open MPI Project is an MPI-3 implementation that is developed and maintained by a consortium of academic, research, and industry partners. Open MPI is therefore able to combine the expertise, technologies, and resources from all across the High Performance Computing community in order to build the best MPI library available. Open MPI offers advantages for system and software vendors, application developers and computer science researchers.

MPI for Python (mpi4py) provides bindings of the Message Passing Interface (MPI) standard for the Python programming language, allowing any Python program to exploit multiple processors.

mpi4py is constructed on top of the MPI-1/MPI-2 specification and provides an object oriented interface which closely follows MPI-2 C++ bindings. It supports point-to-point and collective communications of any picklable Python object as well as optimized communications of Python objects (such as NumPy arrays) that expose a buffer interface.

This version of Open MPI has an implementation of MPI_Init_thread that provides MPI_THREAD_MULTIPLE. This won't work correctly with all transports (such as openib), and the performance is generally worse than the vanilla openmpi package, which only provides MPI_THREAD_FUNNELED.
