    Parallel Function Optimisation Using Evolutionary Algorithms and Deterministic Neighbourhood Search
    (PARS: Parallel-Algorithmen, -Rechnerstrukturen und -Systemsoftware: Vol. 28, No. 1, 2011) Zgeras, Ioannis; Brehm, Jürgen; Reisch, Andreas
    Modern computer hardware provides massive computational power by parallelism. However, many of the existing algorithms and frameworks are optimised for sequential execution and are not capable to be parallelised or do not scale well on complex parallel architectures. In our paper, we present a metaheuristic consisting of a parallel Evolutionary Algorithm and a parallel Neighbourhood Search. For the implementation massively parallel GPUs are used. This framework is evaluated on the application of function optimisation.

    A SSE-Based Implementation of a Ray Tracer for the Comparision with Coprocessors in Hybrid Computing System
    (PARS: Parallel-Algorithmen, -Rechnerstrukturen und -Systemsoftware: Vol. 28, No. 1, 2011) Hampel, Volker; Maehle, Erik
    In this paper we present and discuss our efforts to accelerate a sample application by using the Streaming SIMD Extensions (SSE) to the x64 instruction set. Several approaches to their integration into the source code are tested and evaluated against each other. They are assembler intrinsics, the initial source code combined with different compiler flags, and enhanced code for better SSE inference. Their performances are compared to benchmarks from two hybrid computing systems, which use a Field Programmable Gate Array (FPGA) and a Graphics Processing Unit (GPU), respectively. As the interfaces to manipulated/accelerated code sections are the same in all cases, comparability always is maintained.
