HFusion: A Fusion Tool for Haskell Programs

Fusion is a program transformation technique for the elimination of intermediate data structures in function compositions. Given the composition of two functions the system derives a new definition equivalent to it. This new definition avoids the generation of the intemediate data structure inherent to the original composition.

FASTRA

How much computing power can you cram into a single desktop PC? In our research on image reconstruction we often have to perform large-scale scientific computations, which can easily take weeks on a normal PC. To tackle this problem, we have developed a special PC that is capable of performing our computations just as fast as a cluster consisting of hundreds of PCs. Using this superPC, which consists mainly of gaming hardware and costs less than 4000 euro, we can now perform our three-dimensional reconstructions within a few hours: over 100 times as fast.
