Download or read book Efficient Implementation of Software Release Consistency on Asymmetric Distributed Shared Memory written by Tōkyō Daigaku. Dept. of Information Science and published by . This book was released on 1997 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "The shared memory system can reduce the cost of programming effort in the distributed memory systems. On distributed systems such as networks of computers, it is necessary to provide the shared memory model by software. We have proposed an 'Asymmetric Distributed Shared Memory: ADSM', that provides high-speed-update distributed memory access by software. The compiler for the ADSM translates the code reading to shared memory into a single load instruction and translates the code writing to shared memory into a sequence of instructions, which means instructions managing consistency are separated from the store instruction. The instructions managing consistency are explicitly inserted after the store instruction. According to this property, we can perform various optimizations: (1) We can reduce the number of instructions managing consistency. (2)We can select any protocol per page. We have implemented prototypes of the compiler and the runtime system for the ADSM on a multicomputer Fujitsu AP1000+. We use 3 of the SPLASH-2 kernel benchmarks. We evaluate the effectiveness of the optimization on the ADSM scheme by preliminary experiments."

This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distributed Shared Memory (DSM) is one of the main approaches to implement distributed computing. The purpose of this project is to design and implement a prototype DSM that runs on popular TCP/IP networked Window PCs without special compliers and/or linkers. Our DSM uses lock based scope consistency (ScC), and supports central model, multiple server model and fully distributed model. We use object-oriented method to encapsulate these models within one framework. We provide C++ APIs and a DSM engine for C++ programmers to use DSM functions. The project is developed using C++ and Winsock APIs under Windows NT platform.

Download or read book Fast Lock-free Linked Lists in Distributed Shared Memory Systems written by and published by . This book was released on 1902 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In shared memory systems concurrent processes operate on shared data structures. The consistency of the data structures is maintained by mutual exclusion, which is implemented by locking. Locking is an easy way of ensuring consistency of the shared data structures, but it has several drawbacks. The major drawback is that it increases the latency of all the processes as the shared data structure is accessed in a serial manner. It might also result in deadlocks when the process currently accessing the shared data structure is pre-empted or terminated. An alternate approach to avoid mutual exclusion by locking is by implementing lock-free data structures. This is possible by using basic synchronization primitives such as Compare & Swap and Double Compare & Swap. Processes can concurrently read and write on these data structures and also maintain the consistency of the data structure. Lock-free data structures reduces the latency of the processes and avoids deadlocks. This thesis presents lock-free linked listsalong with the algorithms that operate on them. The algorithms were simulated and were compared with Greenwald & Cheriton's and Valois' algorithms. The design of the linked lists along with the effective and efficient use of the synchronization primitives in the algorithms provides a improved performance over the other two algorithms. The correctness of the algorithms is also presented in the thesis.

Available in PDF, EPUB and Kindle. Book excerpt: This text demystifies the subject of operating systems by using a simple step-by-step approach, from fundamentals to modern concepts of traditional uniprocessor operating systems, in addition to advanced operating systems on various multiple-processor platforms and also real-time operating systems (RTOSs). While giving insight into the generic operating systems of today, its primary objective is to integrate concepts, techniques, and case studies into cohesive chapters that provide a reasonable balance between theoretical design issues and practical implementation details. It addresses most of the issues that need to be resolved in the design and development of continuously evolving, rich, diversified modern operating systems and describes successful implementation approaches in the form of abstract models and algorithms. This book is primarily intended for use in undergraduate courses in any discipline and also for a substantial portion of postgraduate courses that include the subject of operating systems. It can also be used for self-study. Key Features • Exhaustive discussions on traditional uniprocessor-based generic operating systems with figures, tables, and also real-life implementations of Windows, UNIX, Linux, and to some extent Sun Solaris. • Separate chapter on security and protection: a grand challenge in the domain of today’s operating systems, describing many different issues, including implementation in modern operating systems like UNIX, Linux, and Windows. • Separate chapter on advanced operating systems detailing major design issues and salient features of multiple-processor-based operating systems, including distributed operating systems. Cluster architecture; a low-cost base substitute for true distributed systems is explained including its classification, merits, and drawbacks. • Separate chapter on real-time operating systems containing fundamental topics, useful concepts, and major issues, as well as a few different types of real-life implementations. • Online Support Material is provided to negotiate acute page constraint which is exclusively a part and parcel of the text delivered in this book containing the chapter-wise/topic-wise detail explanation with representative figures of many important areas for the completeness of the narratives.

Download or read book Implementing Fine-grain Distributed Shared Memory on Commodity SMP Workstations written by University of Wisconsin--Madison. Computer Sciences Dept and published by . This book was released on 1996 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "This paper reports our experience implementing the Blizzard fine-grain distributed shared memory system on a network of unmodified dual-processor workstations running a commercial operating system. The paper describes and measures: three fine-grain access control mechanisms (optimized software, commodity hardware, and custom hardware); a low-latency, user-level communication layer; kernel support in a commercial operating system; and techniques to exploit multiprocessor (SMP) nodes. The results show that a network of workstations can effectively support fine-grain shared memory, but that high performance requires either custom network hardware or custom coherence protocols."

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Shared memory is widely believed to provide an easier programming model than message passing for expressing parallel algorithms. Distributed Shared Memory (DSM) systems provide the illusion of shared memory on top of standard message passing hardware at very low implementation cost, but provide acceptable performance on only a limited class of applications. In this paper we study the main sources of overhead found in software-coherent, distributed shared-memory systems and argue that recent revolutionary changes in network technology now allow us to design protocols that minimize such overheads and that approach the performance of full hardware coherence. Specifically, we claim that memory-mapped network interfaces that support a global physical address space can greatly improve the performance of DSM systems. To support this claim we study a variety of coherence protocols that can take advantage of the global physical address space and compare their performance with the best known protocol for pure message passing hardware. For the programs in our application suite, protocols taking advantage of the new hardware features improve performance by at least 50% and by as much as an order of magnitude."
