Media praise for High Performance Computing

"The promotional material for this book says that it tells programmers how to tweak code for the new processor architectures. So it does. What they *don't* say is that, once again, they have reached into the depths of the Sebastopol Institute for the Insanely Entertaining and come up with one Kevin Dowd, who explains memory with vacuum cleaners, benchmarks with pie eating contests, and pipelining with kids in the sewer. This is a book on computer architecture that is fun to read. Do you realize how bizarre that is?

"Dowd does, however, know his stuff. Part one covers RISC, memory and optimising compilers. Part two, dealing with porting and tuning code, addresses clarity, identifying porting problems, timing and profiling parallelism, clutter, loops, memory reference, and language issues. Part three looks at benchmarks and performance, while part four gives an introduction to parallel computing.

"Listen, an *executive* could read this. And there's a good chance he'd even *understand* it!"

"As O'Reilly notes in it's promotional material, this book is a departure from their usual handbook orientation. [It] focuses on the world high performance computer architectures -- a subject pretty much restricted to the arcane world of the Cray until the evolution of technology has morphed high-end workstations into Crays during the past two years. The author makes a credible case for the necessity for those writing code for the emerging world of the supermicro to have a pretty solid understanding of how to deal with these new machines described as 'finicky.' Clearly this book is important -- but for a fairly specialized audience." --Book Review, ISOC news, November 1993
