  abstract= "In this paper we compare a Haskell system that exploits a
     GPU back end using Obsidian against a number of other
     GPU/parallel processing systems. Our examples demonstrate
     two major results. Firstly they show that the Haskell
     system allows the applications programmer to exploit GPUs in
     a manner that eases the development of parallel code
     by abstracting from the hardware. Secondly we show that the
     performance results from generating the GPU code from
     Haskell are acceptably comparable to expert hand written GPU
     code in most cases; and permit very significant performance
     benefits over single and multi-threaded implementations
     whilst maintaining ease of development. Where our results
     differ from expert hand written GPU (CUDA) code we consider
     the reasons for this and discuss possible developments that
     may mitigate these differences. We conclude with a
     discussion of a domain specific example that benefits
     directly and significantly from these results."
