SYNTHESIS LECTURES ON COMPUTER ARCHITECTURE P...

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. Table of Contents: GPU Design  Programming  and Trends  
Performance Principles   From Principles to Practice: Analysis and Tuning   Using Detailed
Performance Analysis to Guide Optimization
