Book Description
General-purpose graphics processing unit (GPGPU) is one of the most popular many-core accelerators that deliver a massive computing power in parallel applications. GPGPUs mainly rely on the hardware multithreading to hide a short pipeline stall and a long memory latency. Thus, the performance of GPGPU can be signicantly aected by how GPGPU's hardware multithreading is applied. However, nding the optimal hardware multithreading is a complex problem since there are many aspects to be considered. This work studies the mechanisms for improving the eectiveness of hardware multithreading. First, it studies the various scheduling policies and proposes an adaptive scheduling policy that chooses the best scheduling policy at runtime. In addition, it proposes simple but eective warp throttling mechanism that can increase the cache locality. Furthermore, it proposes a hardware prefetching mechanism to extend the memory latency hiding degree of hardware multithreading. Finally, it shows how a limited scalability of the conventional cache miss handling architecture constrains the degree of hardware multithreading and proposes the highly scalable cache miss handling architecture.

Book Description
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.

Book Description
Originally developed to support video games, graphics processor units (GPUs) are now increasingly used for general-purpose (non-graphics) applications ranging from machine learning to mining of cryptographic currencies. GPUs can achieve improved performance and efficiency versus central processing units (CPUs) by dedicating a larger fraction of hardware resources to computation. In addition, their general-purpose programmability makes contemporary GPUs appealing to software developers in comparison to domain-specific accelerators. This book provides an introduction to those interested in studying the architecture of GPUs that support general-purpose computing. It collects together information currently only found among a wide range of disparate sources. The authors led development of the GPGPU-Sim simulator widely used in academic research on GPU architectures. The first chapter of this book describes the basic hardware structure of GPUs and provides a brief overview of their history. Chapter 2 provides a summary of GPU programming models relevant to the rest of the book. Chapter 3 explores the architecture of GPU compute cores. Chapter 4 explores the architecture of the GPU memory system. After describing the architecture of existing systems, Chapters 3 and 4 provide an overview of related research. Chapter 5 summarizes cross-cutting research impacting both the compute core and memory system. This book should provide a valuable resource for those wishing to understand the architecture of graphics processor units (GPUs) used for acceleration of general-purpose applications and to those who want to obtain an introduction to the rapidly growing body of research exploring how to improve the architecture of these GPUs.

Book Description
Due to excessive power consumptions, limited instruction-level parallelism, escalating processor-memory wall, and available thread-level parallelism in many workloads, computer industry has moved away from building expensive single processor chip with limited performance improvement to multi-core chip for higher chip-level IPCs (Instructions Per Cycle) within an acceptable power budget. Instead of replicating general-purpose Central processing unit (CPU), the recent introduction of Nvidia's and ATI's Graphics Processing Units (GPUs) took a different approach by building many-core GPU as co-processors to connect through a Peripheral Component Interconnect Express (PCI-Express) bus to the host CPU. With hundreds of processing cores and high bandwidth memory systems, the GPU achieves much higher performance than conventional multi-core CPUs. However, GPU also faces many challenges. First, the inability to perform global synchronization among parallel execution thread blocks on GPU forces the parallel applications to synchronize through the host and incur significant overheads. Second, the fair round-robin scheduling scheme in current GPUs often wastes thread-level parallelism due to disparate instruction and memory latencies and encounters heavy stall for long-latency global memory accesses.

Book Description
BrunoBuchberger This book is a synopsis of basic and applied research done at the various re search institutions of the Softwarepark Hagenberg in Austria. Starting with 15 coworkers in my Research Institute for Symbolic Computation (RISC), I initiated the Softwarepark Hagenberg in 1987 on request of the Upper Aus trian Government with the objective of creating a scienti?c, technological, and economic impulse for the region and the international community. In the meantime, in a joint e?ort, the Softwarepark Hagenberg has grown to the current (2009) size of over 1000 R&D employees and 1300 students in six research institutions, 40 companies and 20 academic study programs on the bachelor, master’s and PhD level. The goal of the Softwarepark Hagenberg is innovation of economy in one of the most important current technologies: software. It is the message of this book that this can only be achieved and guaranteed long term by “watering the root”, namely emphasis on research, both basic and applied. In this book, we summarize what has been achieved in terms of research in the various research institutions in the Softwarepark Hagenberg and what research vision we have for the imminent future. When I founded the Softwarepark Hagenberg, in addition to the “watering the root” principle, I had the vision that such a technology park can only prosper if we realize the “magic triangle”, i.e. the close interaction of research, academic education, and business applications at one site, see Figure 1.

Book Description
Multithreaded architectures now appear across the entire range of computing devices, from the highest-performing general purpose devices to low-end embedded processors. Multithreading enables a processor core to more effectively utilize its computational resources, as a stall in one thread need not cause execution resources to be idle. This enables the computer architect to maximize performance within area constraints, power constraints, or energy constraints. However, the architectural options for the processor designer or architect looking to implement multithreading are quite extensive and varied, as evidenced not only by the research literature but also by the variety of commercial implementations. This book introduces the basic concepts of multithreading, describes a number of models of multithreading, and then develops the three classic models (coarse-grain, fine-grain, and simultaneous multithreading) in greater detail. It describes a wide variety of architectural and software design tradeoffs, as well as opportunities specific to multithreading architectures. Finally, it details a number of important commercial and academic hardware implementations of multithreading.
