The p4est software library enables the dynamic management of a collection of adaptive octrees, conveniently called a forest of octrees. p4est is designed to work in parallel and scales to hundreds of thousands of processor cores.

Vc provides portable, zero-overhead C++ types for explicitly data-parallel programming. It is a library designed to ease explicit vectorization of C++ code. Its types enable explicitly stating data-parallel operations on multiple values. The parallelism is therefore added via the type system. Vc has an intuitive API and provides portability between different compilers and compiler versions as well as portability between different vector instruction sets. Thus, an application written with Vc can be compiled for:

1. AVX and AVX2

2. SSE2 up to SSE4.2 or SSE4a

3. Scalar

4. MIC

5. NEON (in development)

6. NVIDIA GPUs / CUDA (in development)

The dune-subgrid module marks elements of another hierarchical dune grid. The set of marked elements can then be accessed as a hierarchical dune grid in its own right. Dune-Subgrid provides the full grid interface including adaptive mesh refinement.

Open CASCADE is a set of libraries for the development of applications dealing with 3D CAD data or requiring industrial 3D capabilities. It includes C++ class libraries providing services for 3D surface and solid modeling, CAD data exchange, and visualization. It is used for development of specialized software dealing with 3D models in design (CAD), manufacturing (CAM), numerical simulation (CAE), measurement equipment (CMM), and quality control (CAQ) domains.

This is the certified version of the Open Cascade Technology (OCCT) library.

HYPRE is a software library of high performance preconditioners and solvers for the solution of large, sparse linear systems of equations. It features multigrid solvers for both structured and unstructured grid problems.

This package provides the non-graphical version of the Scilab software for engineers and scientists. Scilab is used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, numerical optimization, and modeling, simulation of explicit and implicit dynamical systems and symbolic manipulations.
