This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In shared-memory bus-based multiprocessors, the number of processors is often limited by the (shared) bus; when the utilization of the bus approaches 100%, processors spend an increasing amount of time waiting to get access to the bus (and shared memory) and this degrades their performance. The limitations imposed by the bus depend upon many parameters, and different parameters affect the performance in different ways. This chapter uses timed Petri nets to model shared-memory bus-based multiprocessors at the instruction execution level and shows how the performance of processors and the system are affected by different modeling parameters. Discrete-event simulation of the developed net models is used to get performance results.

Available in PDF, EPUB and Kindle. Book excerpt: In a multi-core system, the memory hierarchy and the interconnection network play a dominant role in deciding the performance of the system. In this research, we analyze the dependence of system performance on the interconnection network and memory hierarchy using a set of scientific and engineering workloads. A configuration with a smaller network has low memory access latency, but is more susceptible to memory access conflicts due to fewer memory banks. The extra delay originated from the concurrent memory access conflicts may offset the benefit of shorter latency. So, in this case a larger network with more number of memory banks can benefit from high number of concurrent memory access. This analysis reveals an important tradeoff between employing different sizes of network. Cache sharing on a multi-core processor is usually competitive. Cache coherence problems associated with private caches and the improvement in performance with sharing is analyzed in the last chapter.

This book was released on 1991 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "This simulation-based study examines the behavior of a realistic shared-memory multiprocessor system that utilizes Omega networks. A unique aspect is the presence of bursts of requests, such as processors with associated vector units or caches would generate. It is demonstrated that the forward network, the memory modules, and the reverse network of such a system interact and affect each other's performance such that good performance depends less on the speed of any one component than on the interaction between them. Cost-effective modifications for improving this balance are evaluated. Within the range of system sizes studied (32 to 512 processors), results show that MIN-based systems that operate close to their peak memory bandwidth can indeed be constructed."
Download or read book Shared Memory Consistency Models written by Abdul Naeem and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The shared memory systems should support parallelization at the computation (multiprocessor), communication (Network-on-Chip, NoC) and memory architecture levels to exploit the potential performance benefits. Such systems are facing the critical issues of memory consistency and coherence. Memory consistency issue arises due to the unconstrained operations which sometimes lead to the unexpected behavior of the systems. Memory consistency models are used to resolve this issue. Relaxed or weaker consistency models enforce less ordering constraints on the memory operations and exploit system optimizations compared to the stricter models. This book discusses the novel realization schemes and scalability analysis of strict Sequential Consistency (SC) model and relaxed memory consistency models: Total Store Ordering (TSO), Partial Store Ordering (PSO), Weak Ordering (WO), Release Consistency (RC), and Protected Release Consistency (PRC) in the NoC based distributed shared memory multiprocessor systems. This study should help the average readers and professionals to understand the critical issue of memory consistency both in the NoC based systems and general purpose multiprocessor systems.

Available in PDF, EPUB and Kindle. Book excerpt: A major challenge in multi-core real-time systems is the interference problem on the shared hardware components amongst cores. Examples of these shared components include buses, on-chip caches, and off-chip dynamic random access memories (DRAMs). The problem arises because different cores in the system interfere with each other, while competing to access the shared hardware components. It is a challenging problem for real-time systems because operations of one core affect the temporal behaviour of other cores, which complicates the timing analysis of the system. We address this problem by making the following contributions. 1) For shared buses, we propose CArb, a predictable and criticality-aware arbiter, which provides guaranteed and differential service to tasks based on their requirements. In addition, we utilize CArb to mitigate overheads resulting from system switching among different modes. 2) For the cache hierarchy, we address the problem of maintaining cache coherence in multi-core real-time systems by modifying current coherence protocols such that data sharing is viable for real-time systems in a manner amenable for timing analysis. The proposed solution provides performance improvements, does not impose any scheduling restrictions, and does not require any source-code modifications. 3) At the shared DRAM level, we propose PMC, a programmable memory controller that provides latency guarantees for running tasks upon accessing the off-chip DRAM, while assigning differential memory services to tasks based on their bandwidth and latency requirements. In addition to PMC, we conduct a latency-based analysis on DRAM memory controllers (MCs). Our analysis provides both best-case and worst-case bounds on the latency that any request suffers upon accessing the DRAM. The analysis comprehensively covers all possible interactions of successive requests considering all possible DRAM states. Finally, we formally model request interrelations and DRAM command interactions. We use these models to develop an automated validation framework along with benchmark suites to validate and evaluate PMC and any other MC, which we release as an open-source tool.
