LAPACK is a linear algebra library, based on LINPACK and EISPACK, designed to provide routines for handling simultaneous equations and matrix algebra efficiently, particularly on shared memory vector processors, parallel processors, and clusters. The code is written in Fortran, and requires the BLAS (Basic Linear Algebra Subprograms) library.
The Kent Retargettable Occam Compiler is a multi-platform Occam 2.1 compiler that is designed to allow the Occam programming language to be used on non-Transputer platforms. Extensions from a subset of the Occam 3 specification and from pi calculus have been added over time. As a result, the version of the language supported by the compiler is also sometimes referred to as Occam 2.5 or Occam-pi.
distributed.net is a loosely knit group of computer users from all of the world that is taking up challenges requiring lots of computing power (most notably the RC5, DES, and OGR cracking contests). It is simple to participate in the challenges by downloading and running their client software (which uses idle CPU time to complete its tasks).
ProActive is a Java library for parallel, distributed, and concurrent computing as well as mobility and security in a uniform framework. It provides a comprehensive API and a graphical interface and is based on an Active Object pattern, a uniform way to encapsulate a remotely accessible object, a thread as an asynchronous activity, an actor with its own script, a server of incoming requests, a mobile and secure agent, and a component with server and client interfaces. It simplifies the programming of applications distributed over a LAN, clusters, an intranet, or Internet GRIDs.
MPIBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses MPI and achieves significant speedup on cluster machines. The output of this version is fully compatible with bzip2 1.0.2 or newer (i.e. anything compressed with MPIBZIP2 can be decompressed with bzip2).
DJFractal is yet another fractal generator which distributes fractal data to multiple computers. Fractal data are created locally and distributed to other computers that run the appropriate fractal-generation software, which may be hosted on workstations, or on a Java enabled Web-browser through applets, or on a system with JavaCard. DJFractal's unique feature is the "smart" algorithm it uses to compute (and draw) the most interesting part of a fractal first.
jrMandel is a command line, parallel Mandelbrot set fractal renderer. It is specially designed to render high-resolution fractal images taking advantage of parallel processing, either by using multiple threads of execution (and thus suitable to run on multi-core processors) or by using a Parallel Virtual Machine (PVM) to distribute the tasks among the nodes of a computer cluster. jrMandel can also render fractals without using any parallelism, in order to compare the efficiency between parallel and non-parallel runs.
