Book Description
Abstract: "We describe a new approach to programming distributed-memory computers. Rather than having each node in the system explicitly programmed, we derive an efficient message-passing program from a sequential shared-memory program associated with directions on how elements of shared arrays are distributed to processors. This article describes one possible input language for describing distributions and then details the compilation process and the optimizations necessary to generate an efficient program."

Book Description
Papers presented within this volume cover a wide range of topics related to programming distributed memory machines. Distributed memory architectures, although having the potential to supply the very high levels of performance required to support future computing needs, present awkward programming problems. The major issue is to design methods which enable compilers to generate efficient distributed memory programs from relatively machine independent program specifications. This book is the compilation of papers describing a wide range of research efforts aimed at easing the task of programming distributed memory machines.

Book Description
The benchmark suite covers a variety of problem domains, including dense and sparse matrix operations, tree and graph algorithms, dynamic and data-dependent algorithms, and low- and medium-level image processing applications. The performance results substantiate the claim that data-parallel code can be made to run efficiently on MIMD machines, and demonstrate that compiler optimizations are essential for good performance."

Book Description
Scalable parallel systems or, more generally, distributed memory systems offer a challenging model of computing and pose fascinating problems regarding compiler optimization, ranging from language design to run time systems. Research in this area is foundational to many challenges from memory hierarchy optimizations to communication optimization. This unique, handbook-like monograph assesses the state of the art in the area in a systematic and comprehensive way. The 21 coherent chapters by leading researchers provide complete and competent coverage of all relevant aspects of compiler optimization for scalable parallel systems. The book is divided into five parts on languages, analysis, communication optimizations, code generation, and run time systems. This book will serve as a landmark source for education, information, and reference to students, practitioners, professionals, and researchers interested in updating their knowledge about or active in parallel computing.

Book Description
In brief summary, the following results were presented in this work: • A linear time approach was developed to find register requirements for any specified CS schedule or filled MRT. • An algorithm was developed for finding register requirements for any kernel that has a dependence graph that is acyclic and has no data reuse on machines with depth independent instruction templates. • We presented an efficient method of estimating register requirements as a function of pipeline depth. • We developed a technique for efficiently finding bounds on register require ments as a function of pipeline depth. • Presented experimental data to verify these new techniques. • discussed some interesting design points for register file size on a number of different architectures.

Book Description
The widespread use of object-oriented languages and Internet security concerns are just the beginning. Add embedded systems, multiple memory banks, highly pipelined units operating in parallel, and a host of other advances and it becomes clear that current and future computer architectures pose immense challenges to compiler designers-challenges th
