This book was released on 2012-12-06 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Widespread use of parallel processing will become a reality only if the process of porting applications to parallel computers can be largely automated. Usually it is straightforward for a user to determine how an application can be mapped onto a parallel machine; however, the actual development of parallel code, if done by hand, is typically difficult and time consuming. Parallelizing compilers, which can gen erate parallel code automatically, are therefore a key technology for parallel processing. In this book, Ping-Sheng Tseng describes a parallelizing compiler for systolic arrays, called AL. Although parallelizing compilers are quite common for shared-memory parallel machines, the AL compiler is one of the first working parallelizing compilers for distributed memory machines, of which systolic arrays are a special case. The AL compiler takes advantage of the fine grain and high bandwidth interprocessor communication capabilities in a systolic architecture to generate efficient parallel code. xii Foreword While capable of handling an important class of applications, AL is not intended to be a general-purpose parallelizing compiler.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a revision of my Ph. D. thesis dissertation submitted to Carnegie Mellon University in 1987. It documents the research and results of the compiler technology developed for the Warp machine. Warp is a systolic array built out of custom, high-performance processors, each of which can execute up to 10 million floating-point operations per second (10 MFLOPS). Under the direction of H. T. Kung, the Warp machine matured from an academic, experimental prototype to a commercial product of General Electric. The Warp machine demonstrated that the scalable architecture of high-peiformance, programmable systolic arrays represents a practical, cost-effective solu tion to the present and future computation-intensive applications. The success of Warp led to the follow-on iWarp project, a joint project with Intel, to develop a single-chip 20 MFLOPS processor. The availability of the highly integrated iWarp processor will have a significant impact on parallel computing. One of the major challenges in the development of Warp was to build an optimizing compiler for the machine. First, the processors in the xx A Systolic Array Optimizing Compiler array cooperate at a fine granularity of parallelism, interaction between processors must be considered in the generation of code for individual processors. Second, the individual processors themselves derive their performance from a VLIW (Very Long Instruction Word) instruction set and a high degree of internal pipelining and parallelism. The compiler contains optimizations pertaining to the array level of parallelism, as well as optimizations for the individual VLIW processors.

Kung Although researchers have proposed many mechanisms and theories for parallel systems, only a few have actually resulted in working computing platforms. The iWarp is an experimental parallel system that was designed and built jointly by Carnegie Mellon University and Intel Corporation. The system is based on the idea of integrating a VLIW processor and a sophisticated fine-grained communication system on a single chip. This book describes the complete iWarp system, from instruction-level parallelism to final parallel applications. The authors present a range of issues that must be considered to get a real system into practice. They also provide a start-to-finish history of the project, including what was done right and what was done wrong, that will be of interest to anyone who studies or builds computer systems.

This book was released on 2012-12-06 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the initiative of the IBM Almaden Research Center and the National Science Foundation, a workshop on "Opportunities and Constraints of Parallel Computing" was held in San Jose, California, on December 5-6, 1988. The Steering Committee of the workshop consisted of Prof. R. Karp (University of California at Berkeley), Prof. L. Snyder (University of Washington at Seattle), and Dr. J. L. C. Sanz (IBM Almaden Research Center). This workshop was intended to provide a vehicle for interaction for people in the technical community actively engaged in research on parallel computing. One major focus of the workshop was massive parallelism, covering theory and models of computing, algorithm design and analysis, routing architectures and interconnection networks, languages, and application requirements. More conventional issues involving the design and use of parallel computers with a few dozen processors were not addressed at the meeting. A driving force behind the realization of this workshop was the need for interaction between theoreticians and practitioners of parallel computation. Therefore, a group of selected participants from the theory community was invited to attend, together with well-known colleagues actively involved in parallelism from national laboratories, government agencies, and industry.

Download or read book Dynamically Configurable Systolic Arrays written by Jaisimha K. Durgam and published by . This book was released on 1988 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital signal and image processing and other real time applications involve simple but large amounts of computations. These problems have an enormous amount of inherent parallelism and demand high speed computation. Conventional computers do not possess these characteristics and this had led to the development of new architectural concepts. Among the new architectures, the systolic and wavefront arrays processors have gained a lot of attention because of their high processing bandwidth. The systolic arrays combine massive pipelining with parallelism. There is one problem with this approach of designing application specific chips wherein each of these chips is capable of processing a single algorithm. A number of real time applications require more than one algorithm to be executed for a complete solution. . One solution to the above problem is to develop reconfigurable array structures. One notable proposal is the Confiurable Highly Parallel Computer (CHiP) which is capable of reconfiguring the array to suit different interconnection schemes. In this thesis, the CHiP has been adapted to suit a family of systolic architectures. The dynamically Configurable Systolic Array proposed is designed to accommodate the linear configuration to solve convolution and polynomial multiplication, a square configuration to solve full matrix multiplication and a hexagonal array for band matrix multiplication. The array is a 2-dimensional array arranged in a square grid and functions as an attached processor to a host. Each processor in the array is connected only to it's immediate neighbours and all external communication is only through the edge processors. The actual interconnection patterns are implemented by a set of tristate drivers that are part of the communication links between neighbouring processors. The drivers are controlled by the controller and patterns are determined by the control signals generated. The arithmetic unit is a simple multiplier along with an adder capable of executing the inner product computation common to many signal and image processing applications. The array has been built on a Genesil Silicon Compiler using 2-micron CMOS technology. The three array configurations have been successfully simulated and tested. The algorithms have been executed in times that closely match the theoretical times. More importantly, the feasibility of building a single chip to implement a number of algorithms has been demonstrated and paves the way for further research in this area.

Book excerpt: This work emphasizes the significance of systolic algorithms for massively-parallel computing. It presents, using a unified representation form, a collection of important systolic algorithms for various problems: linear algebra, linear filters, operations with polynomials, comparison problems with some applications to non-linear filtering and data structures, dynamic programming and computational geometry. Design principles and techniques are given and illustrated with concrete examples. The book is also concerned with the results achieved in the past decade in different methodologies for systematic design, efficiency improvement and partitioning of systolic algorithms. In this respect, systolic algorithms still have a unique position among parallel algorithms, in that only this kind of algorithm has mature systematic design techniques. The most important theoretical results achieved in systolic array research are concentrated in Chapter 2 (definitions), Chapter 11 (systematic design) and Chapter 12 (partitioning). The different efficiency improvement techniques are presented when treating concrete algorithms. It should be of great interest to researchers involved in computer science and electrical and computer engineering and to producers of high-performance computers, in particular of massively-parallel computers.
