Hoard is a scalable memory allocator (malloc replacement) for multithreaded applications. Hoard can dramatically improve your application's performance on multicore machines. No changes to your source are necessary; just link it in. Hoard scales linearly up to at least 64 processors. Supported platforms include Linux, Solaris, Mac OS X, and Windows.
SEM2DPACK is a simulator of 2D elastic wave propagation and fracture dynamics that applies the Spectral Element Method (SEM, similar to mass-lumped high-order finite element methods). Flexibility and accuracy are the main goals. Although the emphasis is currently on computational seismology and earthquake source dynamics, this tool might attract a wider audience in computational mechanics, research, and engineering.
xd3d is a simple scientific visualization tool designed to be easy to learn. It can plot 2D and 3D meshes, with shadowing, contour plots, vector fields, iso-contour (3D), as well as 3D surfaces z=f(x,y) defined by an algebraic expression or a cloud of points. It generates high-quality vector PostScript files for scientific publications and still or animated bitmap images. The distribution includes the graph plotter, xgraphic.
astroPluto is modular Godunov-type code intended mainly for astrophysical applications and high Mach number flows in multiple spatial dimensions. The code embeds different hydrodynamic modules and multiple algorithms to solve the equations describing Newtonian, relativistic, MHD, or relativistic MHD fluids in Cartesian or curvilinear coordinates.
Cactus is a general, modular, parallel environment for solving systems of partial differential equations. The code has been developed over many years by a large international collaboration of numerical relativity and computational science research groups and can be used to provide a portable platform for solving any system of partial differential equations.
Open64 is a suite of optimizing compiler development tools for Intel Itanium(TM) systems running Linux. The Open64 project is the continuation of the SGI Pro64(TM) compiler suite which was released under the GNU General Public License (GPL). The Open64 compiler suite currently includes compilers for C, C++, and Fortran90/95 compilers for the IA-64 Linux ABI and API standards.
