Heterogeneous Systems Architecture - a new compute platform infrastructure presents a next-generation hardware platform, and associated software, that allows processors of different types to work efficiently and cooperatively in shared memory from a single source program. HSA also defines a virtual ISA for parallel routines or kernels, which is vendor and ISA independent thus enabling single source programs to execute across any HSA compliant heterogeneous processer from those used in smartphones to supercomputers.

The book begins with an overview of the evolution of heterogeneous parallel processing, associated problems, and how they are overcome with HSA. Later chapters provide a deeper perspective on topics such as the runtime, memory model, queuing, context switching, the architected queuing language, simulators, and tool chains. Finally, three real world examples are presented, which provide an early demonstration of how HSA can deliver significantly higher performance thru C++ based applications. Contributing authors are HSA Foundation members who are experts from both academia and industry. Some of these distinguished authors are listed here in alphabetical order: Yeh-Ching Chung, Benedict R. Gaster, Juan G�mez-Luna, Derek Hower, Lee Howes, Shih-Hao HungThomas B. Jablin, David Kaeli,Phil Rogers, Ben Sander, I-Jui (Ray) Sung.

General-purpose graphics processing units (GPGPU) have emerged as an important class of shared memory parallel processing architectures, with widespread deployment in every computer class from high-end supercomputers to embedded mobile platforms. Relative to more traditional multicore systems of today, GPGPUs have distinctly higher degrees of hardware multithreading (hundreds of hardware thread contexts vs. tens), a return to wide vector units (several tens vs. 1-10), memory architectures that deliver higher peak memory bandwidth (hundreds of gigabytes per second vs. tens), and smaller caches/scratchpad memories (less than 1 megabyte vs. 1-10 megabytes). In this book, we provide a high-level overview of current GPGPU architectures and programming models. We review the principles that are used in previous shared memory parallel platforms, focusing on recent results in both the theory and practice of parallel algorithms, and suggest a connection to GPGPU platforms. We aim to provide hints to architects about understanding algorithm aspect to GPGPU. We also provide detailed performance analysis and guide optimizations from high-level algorithms to low-level instruction level optimizations. As a case study, we use n-body particle simulations known as the fast multipole method (FMM) as an example. We also briefly survey the state-of-the-art in GPU performance analysis tools and techniques.

As Chairmen of HiPEAC 2005, we have the pleasure of welcoming you to the proceedings of the ?rst international conference promoted by the HiPEAC N- work of Excellence. During the last year, HiPEAC has been building its clusters of researchers in computer architecture and advanced compiler techniques for embedded and high-performance computers. Recently, the Summer School has been the seed for a fruitful collaboration of renowned international faculty and young researchers from 23 countries with fresh new ideas. Now, the conference promises to be among the premier forums for discussion and debate on these research topics. Theprestigeofasymposiumismainlydeterminedbythequalityofitstech- cal program. This ?rst programlived up to our high expectations, thanks to the largenumber of strong submissions. The ProgramCommittee received a total of 84 submissions; only 17 were selected for presentation as full-length papers and another one as an invited paper. Each paper was rigorously reviewed by three ProgramCommittee members and at least one external referee. Many reviewers spent a great amount of e?ort to provide detailed feedback. In many cases, such feedback along with constructive shepherding resulted in dramatic improvement in the quality of accepted papers. The names of the Program Committee m- bers and the referees are listed in the proceedings. The net result of this team e?ort is that the symposium proceedings include outstanding contributions by authors from nine countries in three continents. In addition to paper presentations, this ?rst HiPEAC conference featured two keynotes delivered by prominent researchers from industry and academia.
