Kuck, Intel Software, Fellow and Solutions Group, and Director, Parallel and Distributed Solutions, Intel Corporation OpenMP, a portable programming interface for shared memory parallel computers, has been adopted as an informal standard in 1997 by computer scientists who want a single model on which the program to the shared memory system. Using OpenMP offers a comprehensive introduction to parallel programming concepts and detailed overview of OpenMP. Using OpenMP discusses hardware developments, describes where OpenMP applicable, and compares OpenMP to other programming interfaces parallel and distributed shared memory architecture. Finally, Using OpenMP considers trends likely to influence OpenMP development, offering a glimpse of the possibility of a future OpenMP 3.0 from the viewpoint of the current OpenMP 2.5. With multicore computer use increasing, the need for a comprehensive introduction and overview of the standard interface that clearly provides. Using OpenMP important reference not only for students both at undergraduate and postgraduate level, but also for professionals who intend to parallelize existing codes or develop The new parallel programs for shared memory computer architecture.
