Kokkos Core implements a programming model in C++ for writing performance portable applications targeting all major HPC platforms. For that purpose it provides abstractions for both parallel execution of code and data management. Kokkos is designed to target complex node architectures with N-level memory hierarchies and multiple types of execution resources.

Tangled blocks provide a nice way of exporting code into external files, acting as a fantastic agent to write literate dotfile configs. However, such dotfiles tend to be changed externally, sometimes for the worse and sometimes for the better. In the latter case it would be nice to be able to pull those external changes back into the original org src block it originated from.

This module allows you to export an org-file to an Ipython notebook. Python and R notebooks are currently supported. It is not currently possible to mix these languages.

Gyselalib++ is a collection of C++ components for writing gyrokinetic semi-lagrangian codes and similar as well as a collection of such codes.

fortls is a tool known as a language server that interfaces with your code editor (VS Code, Vim, etc.) to provide features like code completion, code navigation, hover messages, and many more.

Library of exchange-correlation functionals for density-functional theory. The aim is to provide a portable, well tested and reliable set of exchange and correlation functionals that can be used by a variety of programs.

Massively parallel library for computing the functions of sparse, Hermitian matrices based on polynomial expansions. For sufficiently sparse matrices, most of the matrix functions in NTPoly can be computed in linear time.

MadMPI benchmark contains the following benchmark series: - base send/recv benchmark, used for reference (mpi_bench_base); - communication/computation overlap benchmark (mpi_bench_overlap); - tag-matching performance with tags of posted receives in order and out of order (mpi_bench_reqs); - multi-threaded communications benchmark (mpi_bench_thread) // preliminary version, still incomplete. Benchmarks are point-to-point, running on two nodes. Collective operations are not benchmarked yet.

Puk is the core of PadicoTM. It manages dynamically loadable modules, software components, and basic data structures (lists, vectors, hashtables, lock-free queues).

PukABI is a dynamic ABI manager. It intercepts symbols using LD_PRELOAD to allow for a variety of features: replace a libc function with a user-supplied function; add hooks for locking with another thread library than libc pthread; add hooks for memory.

PadicoTM is composed of a core which provides a high-performance framework for networking and multi-threading, and services plugged into the core. High-performance communications and threads are obtained thanks to Marcel and Madeleine, provided by the PM2 software suite. The PadicoTM core aims at making the different services running at the same time run in a cooperative way rather than competitive.

NewMadeleine is the fourth incarnation of the Madeleine communication library. The new architecture aims at enabling the use of a much wider range of communication flow optimization techniques. Its design is entirely modular: drivers and optimization strategies are dynamically loadable software components, allowing experimentations with multiple approaches or on multiple issues with regard to processing communication flows. The optimizing scheduler SchedOpt targets applications with irregular, multi-flow communication schemes such as found in the increasingly common application conglomerates made of multiple programming environments and coupled pieces of code, for instance. SchedOpt itself is easily extensible through the concepts of optimization strategies (what to optimize for, what the optimization goal is) expressed in terms of tactics (how to optimize to reach the optimization goal). Tactics themselves are made of basic communication flows operations such as packet merging or reordering. The communication library is fully multi-threaded through its close integration with PIOMan. It manages concurrent communication operations from multiple libraries and from multiple threads. Its MPI implementation Mad-MPI fully supports the MPI_THREAD_MULTIPLE multi-threading level.

hwloc provides a portable abstraction (across OS, versions, architectures, ...) of the hierarchical topology of modern architectures, including NUMA memory nodes, sockets, shared caches, cores and simultaneous multithreading. It also gathers various attributes such as cache and memory information. It primarily aims at helping high-performance computing applications with gathering information about the hardware so as to exploit it accordingly and efficiently.

hwloc may display the topology in multiple convenient formats. It also offers a powerful programming interface to gather information about the hardware, bind processes, and much more.
