Calc is arbitrary precision arithmetic system that uses a C-like language. It's useful as a calculator, an algorithm prototype, and as a mathematical research tool. More importantly, calc provides a machine-independent means of computation. Calc comes with a rich set of builtin mathematical and programmatic functions.
DICElib is an effort to ease the use of clusters to drive applications that need constant synchrony, such as graphical applications, CAVE systems, etc. The library's main features are synchronization, shared memory (which can be synchronous or asynchronous), transparent functions (the same function may do different things in different clients), and use of sockets and TCP/IP.
The Bioinformatics Benchmark System is an attempt to build a reasonable testing framework, tests, and data, to enable end users and vendors to probe the performance of their systems. It is not trying to be the last word in informatics benchmarking, as there are simply too many codes, tests, data sets, and databases. The goal is to create a core of tests that all may download and use to probe specific elements of system performance. The end goal is to enable a pluggable set of tests, including the core tests, so that performance data may be gathered.
