Facing the multicore-challenge : aspects of new paradigms and technologies in parallel computing : conference held at Heidelberg, Germany, 17-19.03.2010

Annotation This state-of-the-art survey features topics related to the impact of multicore and coprocessor technologies in science and for large-scale applications in an interdisciplinary environment. The papers cover all issues of current research in mathematical modeling, design of parallel algorithms, aspects of microprocessor architecture, parallel programming languages, compilers, hardware-aware computing, heterogeneous platforms, emerging architectures, tools, performance tuning, and requirements for large-scale applications. The contributions presented in this volume offer a survey on the state of the art, the concepts and perspectives for future developments. They are an outcome of an inspiring conference conceived and organized by the editors within the junior scientist program of Heidelberg Academy for Sciences and Humanities titled "Facing the Multicore-Challenge", held at Heidelberg, Germany, in March 2010. The 12 revised full papers presented together with the extended abstracts of 3 invited lectures focus on combination of new aspects of multicore microprocessor technologies, parallel applications, numerical simulation, software development, and tools; thus they clearly show the potential of emerging technologies in the area of multicore and manycore processors that are paving the way towards personal supercomputing Front Matter....Pages - Analyzing Massive Social Networks Using Multicore and Multithreaded Architectures....Pages 1-1 MareIncognito: A Perspective towards Exascale....Pages 2-2 The Natural Parallelism....Pages 3-3 RapidMind: Portability across Architectures and Its Limitations....Pages 4-15 A Majority-Based Control Scheme for Way-Adaptable Caches....Pages 16-28 Improved Scalability by Using Hardware-Aware Thread Affinities....Pages 29-41 Thread Creation for Self-aware Parallel Systems....Pages 42-53 G-Means Improved for Cell BE Environment....Pages 54-65 Parallel 3D Multigrid Methods on the STI Cell BE Architecture....Pages 66-78 Applying Classic Feedback Control for Enhancing the Fault-Tolerance of Parallel Pipeline Workflows on Multi-core Systems....Pages 79-91 Lattice-Boltzmann Simulation of the Shallow-Water Equations with Fluid-Structure Interaction on Multi- and Manycore Processors....Pages 92-104 FPGA vs. Multi-core CPUs vs. GPUs: Hands-On Experience with a Sorting Application....Pages 105-117 Considering GPGPU for HPC Centers: Is It Worth the Effort?....Pages 118-130 Real-Time Image Segmentation on a GPU....Pages 131-142 Parallel Volume Rendering Implementation on Graphics Cards Using CUDA....Pages 143-153 Back Matter....Pages - This survey of the impact of multicore and co-processor technologies on science as well as on large-scale interdisciplinary applications covers the state of the art in the field.
