This book constitutes the proceedings of the SPEC Benchmark Workshop 2009 held in Austin, Texas, USA on January 25th, 2009. The 9 papers presented were carefully selected and reviewed for inclusion in the book. The result is a collection of high-quality papers discussing current issues in the area of benchmarking research and technology. The topics covered are: benchmark suites, CPU benchmarking, power/thermal benchmarking, and modeling and sampling techniques.
This book teaches OpenCL and parallel programming for complex systems with various device architectures, including multi-core CPUs, GPUs, and Accelerated Processing Units (APUs). The revised edition covers the latest enhancements in OpenCL 2.0, such as shared virtual memory to enhance programming flexibility and reduce resource-consuming data transfers, dynamic parallelism to alleviate processor load and prevent bottlenecks, and improved imaging support with OpenGL integration. Designed for multiple platforms, OpenCL facilitates effective programming for a heterogeneous future. Authored by experts in parallel computing and OpenCL, the book delves into memory spaces, optimization techniques, extensions, debugging, and profiling. It features multiple case studies and examples that illustrate high-performance algorithms, work distribution across heterogeneous systems, and embedded domain-specific languages, providing hands-on OpenCL experience for tackling fundamental parallel algorithms. Updated content addresses the latest developments in memory handling, parallelism, and imaging support. The book also explains principles and strategies for learning parallel programming with OpenCL, covering abstraction models and thorough application testing and debugging, along with example code for image analytics, web plugins, particle simulations, video editing, and performance optimization.
