A guide to advanced features of MPI, reflecting the latest version of the MPI standard, that takes an example-driven, tutorial approach. This book offers a practical guide to the advanced features of the MPI (Message-Passing Interface) standard library for writing programs for parallel computers. It covers new features added in MPI-3, the latest version of the MPI standard, and updates from MPI-2. Like its companion volume, Using MPI, the book takes an informal, example-driven, tutorial approach. The material in each chapter is organized according to the complexity of the programs used as examples, starting with the simplest example and moving to more complex ones. Using Advanced MPI covers major changes in MPI-3, including changes to remote memory access and one-sided communication that simplify semantics and enable better performance on modern hardware; new features such as nonblocking and neighborhood collectives for greater scalability on large systems; and minor updates to parallel I/O and dynamic processes. It also covers support for hybrid shared-memory/message-passing programming; MPI_Message, which aids in certain types of multithreaded programming; features that handle very large data; an interface that allows the programmer and the developer to access performance data; and a new binding of MPI to Fortran.
The thoroughly updated edition of a guide to parallel programming with MPI, reflecting the latest specifications, with many detailed examples. This book offers a thoroughly updated guide to the MPI (Message-Passing Interface) standard library for writing programs for parallel computers. Since the publication of the previous edition of Using MPI, parallel computing has become mainstream. Today, applications run on computers with millions of processors; multiple processors sharing memory and multicore processors with multiple hardware threads per core are common. The MPI-3 Forum recently brought the MPI standard up to date with respect to developments in hardware capabilities, core language evolution, the needs of applications, and experience gained over the years by vendors, implementers, and users. This third edition of Using MPI reflects these changes in both text and example code. The book takes an informal, tutorial approach, introducing each concept through easy-to-understand examples, including actual code in C and Fortran. Topics include using MPI in simple programs, virtual topologies, MPI datatypes, parallel libraries, and a comparison of MPI with sockets. For the third edition, example code has been brought up to date; applications have been updated; and references reflect the recent attention MPI has received in the literature. A companion volume, Using Advanced MPI, covers more advanced topics, including hybrid programming and coping with large data.
Covers the colonial origins of the three infantry regiments that comprise the Blue and Gray Division,"" the establishment of the Division in 1917, and its current status as a light infantry division in the Maryland National Guard. Contains an emphasis on the history of the 29th Infantry Division in WWII. Map displaying activity of 29th Division from June 6, 1944 through January 1, 1945 on endsheets. Hundreds of photos. Indexed
Planning at a metropolitan scale is important for effective management of urban growth, transportation systems, air quality, and watershed and green-spaces. It is fundamental to efforts to promote social justice and equity. Best Practices in Metropolitan Transportation Planning shows how the most innovative metropolitan planning organizations (MPOs) in the United States are addressing these issues using their mandates to improve transportation networks while pursuing emerging sustainability goals at the same time. As both a policy analysis and a practical how-to guide, this book presents cutting-edge original research on the role accessibility plays - and should play - in transportation planning, tracks how existing plans have sought to balance competing priorities using scenario planning and other strategies, assesses the results of various efforts to reduce automobile dependence in cities, and explains how to make planning documents more powerful and effective. In highlighting the most innovative practices implemented by MPOs, regional planning councils, city and county planning departments and state departments of transportation, this book aims to influence other planning organizations, as well as influence federal and state policy discussions and legislation.
