Available in PDF, EPUB and Kindle. Book excerpt: Algorithms that have to process large data sets have to take into account that the cost of memory access depends on where the data is stored. Traditional algorithm design is based on the von Neumann model where accesses to memory have uniform cost. Actual machines increasingly deviate from this model: while waiting for memory access, nowadays, microprocessors can in principle execute 1000 additions of registers; for hard disk access this factor can reach six orders of magnitude. The 16 coherent chapters in this monograph-like tutorial book introduce and survey algorithmic techniques used to achieve high performance on memory hierarchies; emphasis is placed on methods interesting from a theoretical as well as important from a practical point of view.

Available in PDF, EPUB and Kindle. Book excerpt: The simplest topology supported by SCI is the ring. It was found that, for the hardware and software simulated, the largest efficient ring size is between eight and sixteen nodes and that raw network bandwidth seen by processing elements is limited at about 80Mbytes/s. This is because the network saturates when link traffic reaches 600- 7000Mbytes/s. These levels of link traffic only occur for two poorly designed programs. The other four programs generate low traffic and their execution speed is not limited by interconnect nor cache coherence protocol. An analytical model of the multiprocessor is used to assess the cost of some frequently occurring cache coherence protocol operations. In order to build large systems, networks more sophisticated than rings must be used. The performance of SCI meshes and cubes is evaluated for systems of up to 64 nodes. As with rings, processor throughput is also limited by link traffic for the same two poorly designed programs

Available in PDF, EPUB and Kindle. Book excerpt: The effective and efficient use of the memory hierarchy of the computer system is one of the, if not the single most important aspect of computer system design and use. Cache memory performance is often the limiting factor in CPU performance and cache memories also serve to cut the memory traffic in multiprocessor systems. Multiprocessor systems are also requiring advances in cache architecture with respect to cache consistency. Similarly, the study of the best means to share main memory is an important research topic. Disk cache is becoming important for performance in high end computer systems and is now widely available commercially; there are many related research problems. The development of mass storage, especially optical disk, will promote research in effective algorithms for file management and migration. In this paper, we look at each component of the memory hierarchy and address two issues: what are likely directions for development, and what are the interesting research problems.

This book was released on 2005-11-24 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The architectural concept of a memory hierarchy has been immensely successful, making possible today's spectacular pace of technology evolution in both the volume of data and the speed of data access. Its success is difficult to understand, however, when examined within the traditional "memoryless" framework of performance analysis. The `memoryless' framework cannot properly reflect a memory hierarchy's ability to take advantage of patterns of data use that are transient. The Fractal Structure of Data Reference: Applications to the Memory Hierarchy both introduces, and justifies empirically, an alternative modeling framework in which arrivals are driven by a statistically self-similar underlying process, and are transient in nature. The substance of this book comes from the ability of the model to impose a mathematically tractable structure on important problems involving the operation and performance of a memory hierarchy. It describes events as they play out at a wide range of time scales, from the operation of file buffers and storage control cache, to a statistical view of entire disk storage applications. Striking insights are obtained about how memory hierarchies work, and how to exploit them to best advantage. The emphasis is on the practical application of such results. The Fractal Structure of Data Reference: Applications to the Memory Hierarchy will be of interest to professionals working in the area of applied computer performance and capacity planning, particularly those with a focus on disk storage. The book is also an excellent reference for those interested in database and data structure research.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "With the increasing gap between processor speed and memory speed, a sophisticated memory hierarchy is key to high performance. However, the operating system tends to use the memory hierarchy poorly. This thesis presents a comprehensive characterization and optimization of the performance of multiprocessor memory hierarchies for operating systems. The operating system instruction cache misses are reduced by 81% using a code reorganization scheme tailored to the operating system, guarded sequential prefetching, and stream buffers. The operating system data cache misses are reduced by 53% using a DMA-like pipelined block transfer engine, a selective update protocol, data relocation and privatization, and data prefetching in miss hot spots. The overall OS time is reduced by 32%. The cost-performance trade-offs of the software/hardware optimization schemes are also discussed."

This book was released on 2015-12-01 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis lecture presents the current state-of-the-art in applying low-latency, lossless hardware compression algorithms to cache, memory, and the memory/cache link. There are many non-trivial challenges that must be addressed to make data compression work well in this context. First, since compressed data must be decompressed before it can be accessed, decompression latency ends up on the critical memory access path. This imposes a significant constraint on the choice of compression algorithms. Second, while conventional memory systems store fixed-size entities like data types, cache blocks, and memory pages, these entities will suddenly vary in size in a memory system that employs compression. Dealing with variable size entities in a memory system using compression has a significant impact on the way caches are organized and how to manage the resources in main memory. We systematically discuss solutions in the open literature to these problems. Chapter 2 provides the foundations of data compression by first introducing the fundamental concept of value locality. We then introduce a taxonomy of compression algorithms and show how previously proposed algorithms fit within that logical framework. Chapter 3 discusses the different ways that cache memory systems can employ compression, focusing on the trade-offs between latency, capacity, and complexity of alternative ways to compact compressed cache blocks. Chapter 4 discusses issues in applying data compression to main memory and Chapter 5 covers techniques for compressing data on the cache-to-memory links. This book should help a skilled memory system designer understand the fundamental challenges in applying compression to the memory hierarchy and introduce him/her to the state-of-the-art techniques in addressing them.

Available in PDF, EPUB and Kindle. Book excerpt: The State of Memory Technology Over the past decade there has been rapid growth in the speed of micropro cessors. CPU speeds are approximately doubling every eighteen months, while main memory speed doubles about every ten years. The International Tech nology Roadmap for Semiconductors (ITRS) study suggests that memory will remain on its current growth path. The ITRS short-and long-term targets indicate continued scaling improvements at about the current rate by 2016. This translates to bit densities increasing at two times every two years until the introduction of 8 gigabit dynamic random access memory (DRAM) chips, after which densities will increase four times every five years. A similar growth pattern is forecast for other high-density chip areas and high-performance logic (e.g., microprocessors and application specific inte grated circuits (ASICs)). In the future, molecular devices, 64 gigabit DRAMs and 28 GHz clock signals are targeted. Although densities continue to grow, we still do not see significant advances that will improve memory speed. These trends have created a problem that has been labeled the Memory Wall or Memory Gap.
