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.

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.

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.

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

ADIOS2 transports data as groups of self-describing variables and attributes across different media types (such as files, wide-area-networks, and remote direct memory access) using a common application programming interface for all transport modes. ADIOS2 can be used on supercomputers, cloud systems, and personal computers.

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.

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.

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.

A Fortran 2008 library to locally intersect two overlapping meshes. Overlapping elements are identified and a local supermesh of their intersection is generated.

C++ implementation of a R*-tree, an MVR-tree and a TPR-tree with C API.

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.

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.

PIOMan is an I/O event manager of the PM2 software suite. It ensures communication progression using available cores and hooks in thread scheduler. It guarantees good reactivity, asynchronous communication progression, and communication/computation overlap. PIOMan is closely integrated with the NewMadeleine communication library and PadicoTM. It works with three flavors of thread scheduling: no thread, pthread, and Marcel. The pthread flavor may be composed with various runtime systems such as OpenMP. PIOMan can be used standalone to bring low level asynchronous progression in a communication library, or more simply may be used through the NewMadeleine communication library and its companion MPI implementation called Mad-MPI supporting MPI_THREAD_MULTIPLE multi-threading level.

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.

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.

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