Conduit is a project from Lawrence Livermore National Laboratory that provides an intuitive model for describing hierarchical scientific data in C++, C, Fortran, and Python. It is used for data coupling between packages in-core, serialization, and I/O tasks.

Adiak is a library for recording meta-data about HPC simulations. An HPC application code may, for example, record what user invoked it, the version of the code being run, a computed time history showing density changes, or how long the application spent performing file IO. Adiak represents this metadata as Name/Value pairs. Names are arbitrary strings, with some standardization, and the values are represented by a flexible dynamic type system

HDF5 is a suite that makes possible the management of extremely large and complex data collections.

LvArray is a collection of container classes designed for performance portability in that they are usable on the host and device and provide performance similar to direct pointer manipulation

librsb is a library for sparse matrix computations featuring the Recursive Sparse Blocks (RSB) matrix format. This format allows cache efficient and multi-threaded (that is, shared memory parallel) operations on large sparse matrices. The most common operations necessary to iterative solvers are available, e.g.: matrix-vector multiplication, triangular solution, rows/columns scaling, diagonal extraction / setting, blocks extraction, norm computation, formats conversion. The RSB format is especially well suited for symmetric and transposed multiplication variants. Most numerical kernels code is auto generated, and the supported numerical types can be chosen by the user at build time. librsb can also be built serially (without OpenMP parallelism), if required. librsb also implements the Sparse BLAS standard, as specified in the [BLAS Technical Forum] documents.

Mongoose is a graph partitioning library. Currently, Mongoose only supports edge partitioning, but in the future a vertex separator extension will be added.

Not Another Completely Heuristic Operating System, or Nachos, is instructional software for teaching undergraduate, and potentially graduate level operating systems courses. As this stage, the package only processes the kernel part (but not the ./test/ part).

PajeNG (Paje Next Generation) is a re-implementation (in C++) and direct heir of the well-known Paje visualization tool for the analysis of execution traces (in the Paje File Format) through trace visualization (space/time view). The tool is released under the GNU General Public License 3. PajeNG comprises the libpaje library, and a set of auxiliary tools to manage Paje trace files (such as pj_dump and pj_validate). The space-time visualization tool called pajeng is deprecated (removed from the sources) since modern tools do a better job (see pj_gantt, for instance, or take a more general approach using R+ggplot2 to visualize the output of pj_dump). This effort was started as part of the french INFRA-SONGS ANR project. Development has continued through a collaboration between INF/UFRGS and INRIA.

AVBP is a 3D Navier-Stokes compressible DNS/LES solver co-developped by CERFACS and IFP-EN until version 7.3. Since, CERFACS ensures the alone development and improvement of the code.

This is a package used to run an AVBP test suite.

A collection of host-based and device-based microbenchmarks for MPI communication with CUDA support.

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.

The official GitLab Runner written in Go. It runs tests and sends the results to GitLab. GitLab CI is the open-source continuous integration service included with GitLab that coordinates the testing.

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

Ginkgo is a high-performance numerical linear algebra library for many-core systems, with a focus on solution of sparse linear systems.

MUMPS (MUltifrontal Massively Parallel sparse direct Solver) solves a sparse system of linear equations A x = b using Gaussian elimination.
