This book was released on 1993 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Current and emerging high-performance parallel computer architectures generally implement one of the two types of communication mechanisms: Shared memory (SM) or message passing (MP). In this paper we propose a hybrid SM/MP architecture together with a hybrid SM/MP programming model, that we believe effectively combines the advantages of each system. The SM/MP architecture contains both a high- performance coherence protocol for shared memory, and message-passing primitives that coexist with the coherence protocol but have no coherence overhead. The SM/MP programming model provides a framework for safely and effectively using the SM/MP communication primitives. We illustrate the use of the model and primitives to reduce communication overhead in SM systems."

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The hybrid message passing + shared memory programming model combines two parallel programming styles within the same application in an effort to improve the performance and efficiency of parallel codes on modern multi-core clusters. This thesis presents a performance study of this model as it applies to two Molecular Dynamics (MD) applications. Both a large scale production MD code and a smaller scale example MD code have been adapted from existing message passing versions by adding shared memory parallelism to create hybrid message passing + shared memory applications. The performance of these hybrid applications has been investigated on different multi-core clusters and compared with the original pure message passing codes. This performance analysis reveals that the hybrid message passing + shared memory model provides performance improvements under some conditions, while the pure message passing model provides better performance in others. Typically, when running on small numbers of cores the pure message passing model provides better performance than the hybrid message passing + shared memory model, as hybrid performance suffers due to increased overheads from the use of shared memory constructs. However, when running on large numbers of cores the hybrid model performs better as these shared memory overheads are minimised while the pure message passing code suffers from increased communication overhead. These results depend on the interconnect used. Hybrid message passing + shared memory molecular dynamics codes are shown to exhibit different communication profiles from their pure message passing versions and this is revealed to be a large factor in the performance difference between pure message passing and hybrid message passing + shared memory codes. An extension of this result shows that the choice of interconnection fabric used in a multi-core cluster has a large impact on the performance difference between the pure message passing and the hybrid code. The factors affecting the performance of the applications have been analytically examined in an effort to describe, generalise and predict the performance of both the pure message passing and hybrid message passing + shared memory codes.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Message-passing and shared-memory each have their respective advantages and disadvantages in distributed parallel programming. Message-passing gives explicit control of communication but the model may require much programming effort for dynamic communication patterns and high overheads when communicating complex, pointer-based data structures. With shared-memory, communication is implicit and therefore considered easier to program. But shared-memory implementations may not perform optimally for certain sharing patterns. A new hybrid programming model that integrates distributed shared memory (DSM) and message-passing is therefore proposed along with a new memory consistency model called Message-Driven Consistency (MDC). MDC is based on annotated messages that interact with the consistency mechanisms of a shared-memory

Available in PDF, EPUB and Kindle. Book excerpt: This historical survey of parallel processing from 1980 to 2020 is a follow-up to the authors’ 1981 Tutorial on Parallel Processing, which covered the state of the art in hardware, programming languages, and applications. Here, we cover the evolution of the field since 1980 in: parallel computers, ranging from the Cyber 205 to clusters now approaching an exaflop, to multicore microprocessors, and Graphic Processing Units (GPUs) in commodity personal devices; parallel programming notations such as OpenMP, MPI message passing, and CUDA streaming notation; and seven parallel applications, such as finite element analysis and computer vision. Some things that looked like they would be major trends in 1981, such as big Single Instruction Multiple Data arrays disappeared for some time but have been revived recently in deep neural network processors. There are now major trends that did not exist in 1980, such as GPUs, distributed memory machines, and parallel processing in nearly every commodity device. This book is intended for those that already have some knowledge of parallel processing today and want to learn about the history of the three areas. In parallel hardware, every major parallel architecture type from 1980 has scaled-up in performance and scaled-out into commodity microprocessors and GPUs, so that every personal and embedded device is a parallel processor. There has been a confluence of parallel architecture types into hybrid parallel systems. Much of the impetus for change has been Moore’s Law, but as clock speed increases have stopped and feature size decreases have slowed down, there has been increased demand on parallel processing to continue performance gains. In programming notations and compilers, we observe that the roots of today’s programming notations existed before 1980. And that, through a great deal of research, the most widely used programming notations today, although the result of much broadening of these roots, remain close to target system architectures allowing the programmer to almost explicitly use the target’s parallelism to the best of their ability. The parallel versions of applications directly or indirectly impact nearly everyone, computer expert or not, and parallelism has brought about major breakthroughs in numerous application areas. Seven parallel applications are studied in this book.
