The Amsterdam Compiler Kit is a fully-featured retargetable compiler toolchain. It will cross-compile ANSI C, K&R C, Pascal, Modula-2, Occam, Fortran and Basic for a number of architectures including, but not limited to, the 6500, 68000, Z80, i80, i86, i386, and PDP-11. It provides a complete development environment including preprocessors, compilers, assemblers, linkers, librarian tools, and target download tools.
Stanford Exploration Project Library (SEPlib) is a software package that was developed to manipulate and process many types of geophysical data. It includes libraries for manipulating 2D and 3D data and pipe-fed command-line utilities. It has support for parallelization through MPI and OpenMP and supports connectors to other geophysical packages.
The GotoBLAS codes are a fast implementation of the Basic Linear Algebra Subroutines. The advantage is fast calculation. Note that the actual performance depends in part on the code from which you call the GotoBLAS subroutine(s), and on the combination of architecture and operating system under which you are running. Your own tuning can make a big difference.
octopus is a program aimed at the ab initio virtual experimentation on a hopefully ever increasing range of systems types. Electrons are describe quantum-mechanically within the Density-Functional Theory (DFT), in its time-dependent form (TDDFT) when doing simulations in time. Nuclei are described classically as point particles. Electron-nucleus interaction is described within the Pseudopotential approximation.
GSEGYView is a viewer for seismic data in SEG-Y format, its modifications, and many other related formats aimed to store either petroleum exploration data or seismology data. GSEGYView features graphics hardware acceleration via OpenGL for seismic data rendering, wiggle, variable area and variable density seismic traces representation, two-level sorting of seismic traces by arbitratry keys in trace headers, multiple windows for multiple files with separate display parameters, easy seismic section navigation and zoom with mouse wheel support, and more.
NightStar is a suite of debugging and analysis tools for Linux software development. NightStar tools are minimally intrusive, allowing users to locate bugs, find timing bottlenecks, and analyze multi-threaded and multi-process interactions while preserving application execution behavior and determinism. NightStar includes a complete source-level debugger, a trace utility that offers a graphic view of kernel interactions, a data monitor, and a system and application performance tuner.
Babel is an IDL-based language interoperability tool specific to engineering and scientific applications. It allows Fortran 77, Fortran 90, C, C++, Java, and Python to call each other in a single address space for maximum performance. Babel won a 2006 R&D 100 award from R&D Magazine.
