PETSc is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. It employs the MPI standard for all message-passing communication.

This package contains the headers and static library files necessary for building C++ programs which use libstdc++.

This is used to develop subsets of the libstdc++ shared libraries for use on custom installation floppies and in embedded systems.

Open3D is an open-source library that supports rapid development of software that deals with 3D data. The Open3D frontend exposes a set of carefully selected data structures and algorithms in both C++ and Python. The backend is highly optimized and is set up for parallelization.

This is the GNU Objective-C compiler, which compiles Objective-C on platforms supported by the gcc compiler.
