High Performance Computing Programming and Applications

Covering all three levels of parallelism, this book presents techniques that address performance issues in the programming of HPC applications. Drawing on their experience with chips from AMD and systems, interconnects, and software from Cray Inc., the authors explore the problems that create bottle...
