This is the GNU Objective-C compiler for the i686-linux-gnu architecture, which compiles Objective-C on platforms supported by the gcc compiler. It uses the gcc backend to generate optimized code.

NOX robustly solves and analyzes large-scale systems of nonlinear equations. NOX is short for Nonlinear Object-Oriented Solutions, and its objective is to enable the robust and efficient solution of the equation: F(x)=0 using globalized Newton methods such as line search and trust region methods. NOX is designed to work with any linear algebra package and to be easily customized.

PAMGEN creates hexahedral or quadrilateral (in 2D) finite element meshes of simple shapes (cubes and cylinders) in parallel. When linked to an application as a library, it allows each process of a parallel simulation to generate its finite element domain representation at execution time.

Pliris is an object-oriented interface to a LU solver for dense matrices on parallel platforms. These matrices are double precision real matrices distributed on a parallel machine.

The Rapid Optimization Library (ROL) is a package for large-scale optimization. It is used for the solution of optimal design, optimal control and inverse problems in large-scale engineering applications. Other uses include mesh optimization and image processing.

RTOp (reduction/transformation operators) provides the basic mechanism for implementing vector operations in a flexible and efficient manner.
