Book excerpt: Abstract: "The IBM 360/85, possibly the first commercially available CPU with a cache memory, used a cache with a sector design, by which the cache consisted of sectors (with address tags) and subsectors (or blocks, with valid bits). It rapidly became clear that superior performance could be obtained with the now familiar set-associative cache design. Because of changes in technology, the time has come to revisit the design of sector caches. Sector caches have the feature that large numbers of bytes can be tagged using relatively small numbers of tag bits, while still only transferring small blocks when a miss occurs. This suggests the use of sector caches for multilevel cache designs. In such a design, the cache tags can be placed at a higher level (e.g., on the processor chip) and the cache data array can be placed at a lower level (e.g., off-chip). In this paper, we present a thorough analysis of the design and use of uniprocessor sector caches. We start by creating a standard workload and then we calculate miss ratios for a wide range of sector cache designs. Those miss ratios are transformed into Design Target Miss Ratios, which are intended to be 'typical' miss ratios, suitable for use for design purposes ('design targets'). The miss ratios are then used to estimate performance, using typical timings, for a variety of one level and two level cache designs. We find that for single level caches, sector caches are seldom advantageous. For multilevel cache designs with small amounts of storage at the first level caches, as would be the case for small on-chip caches, sector caches can yield significant performance improvements. For multilevel designs with large amounts of first level storage, sector caches provide relatively small improvements."

Available in PDF, EPUB and Kindle. Book excerpt: An authoritative book for hardware and software designers. Caches are by far the simplest and most effective mechanism for improving computer performance. This innovative book exposes the characteristics of performance-optimal single and multi-level cache hierarchies by approaching the cache design process through the novel perspective of minimizing execution times. It presents useful data on the relative performance of a wide spectrum of machines and offers empirical and analytical evaluations of the underlying phenomena. This book will help computer professionals appreciate the impact of caches and enable designers to maximize performance given particular implementation constraints.

Book excerpt: Abstract: "Sector caches use an address tag to identify a sector, and valid bits to indicate whether each subsector is present in the cache. This design permits a small number of tag bits to control a large number of data bytes in the cache. Such a design is useful for single level caches when cache sizes are small and/or when the optimal line sizes are small. Sector caches are most useful when small first-level tag arrays are used to control large second level cache data arrays. The problem with sector caches is that because of the constrained mapping between address tags and data array space, frequently many of the subsectors are not filled before the new sector is replaced. In this paper, we propose a new design, called the sector pool cache, in which subsectors may be shared between sectors, so that the cache data arrays are used much more efficiently. We evaluate this design using a large multiprogrammed workload to provide a more realistic test of the various cache designs. Our results show that the sector pool cache can be an attractive solution for a first level on-chip cache when used in conjunction with a regular second level off-chip sector cache. Such a design provides improved performance by allowing a larger fraction of first level cache bits to be used for data rather than for tags."

The success of these symposia indicates the importance of this area and the strong interest of the research community. With all of the recent drastic changes in HPC technology trends, HPC has had and will continue to have a signi?cant impact on computer science and technology. I am pleased to serve as General Chair at a time when HPC plays a crucial role in the era of the IT (Information Technology) revolution. The objective of this symposium is to exchange the latest research results in software, architecture, and applications in HPC in a more informal and friendly atmosphere. I am delighted that the symposium is, like past successful ISHPCs, comprised of excellent invited talks, panels, workshops, as well as high-quality technical papers on various aspects of HPC. We hope that the symposium will provide an excellent opportunity for lively exchange and discussion about - rections in HPC technologies and all the participants will enjoy not only the symposium but also their stay in Kansai Science City.

Book excerpt: As we continue to build faster and fast. er computers, their performance is be coming increasingly dependent on the memory hierarchy. Both the clock speed of the machine and its throughput per clock depend heavily on the memory hierarchy. The time to complet. e a cache acce88 is oft. en the factor that det. er mines the cycle time. The effectiveness of the hierarchy in keeping the average cost of a reference down has a major impact on how close the sustained per formance is to the peak performance. Small changes in the performance of the memory hierarchy cause large changes in overall system performance. The strong growth of ruse machines, whose performance is more tightly coupled to the memory hierarchy, has created increasing demand for high performance memory systems. This trend is likely to accelerate: the improvements in main memory performance will be small compared to the improvements in processor performance. This difference will lead to an increasing gap between prOCe880r cycle time and main memory acce. time. This gap must be closed by improving the memory hierarchy. Computer architects have attacked this gap by designing machines with cache sizes an order of magnitude larger than those appearing five years ago. Microproce880r-based RISe systems now have caches that rival the size of those in mainframes and supercomputers.

Available in PDF, EPUB and Kindle. Book excerpt: This disseration describes innovative techniques for efficiently analyzing a wide variety of cache designs, and uses these techniques to study caching in a network file system. The techniques are significant extensions to the stack analysis technique (Mattson et al., 1970) which computes the read miss ratio for all cache sizes in a single trace-driven simulation. Stack analysis is extended to allow the one-pass analysis of: 1) writes in a write-back cache, including periodic write-back and deletions, important factors in file system cache performance. 2) sub-block or sector caches, including load-forward prefetching. 3) multi-processor caches in a shared-memory system, for an entire class of consistency protocols, including all of the well-known protocols. 4) client caches in a network file system, using a new class of consistency protocols. The techniques are completely general and apply to all levels of memory hierarchy, for processor caches to disk and file system caches. The disseration also discusses the use of hash table and binary trees within the simulator to further improve performance for some types of traces. Using these techniques, the performance of all cache sizes can be computed in little more than twice the time required to simulate a single cache size, and often in just 10% more time. In addition to resenting techniques, this disseration also demonstrates their use by studying client caching in a network file system. It first reports the extent of file sharing in a UNIX environment, showing that a few shared files account for two-thirds of all accesses, and nearly half of these are to files which are both read and written. It then studies different cache consistency protocols, write policies, and fetch policies, reporting the miss ratio and file server utilization for each. Four cache consistency protocols are considered: a polling protocol that uses the server for all consistency controls; a protocol designed for single-user files; one designed for read-only files; and one using write-broadcast to maintain consistency. It finds that the choice of consistency protocol has substantial effect on performance; both the read- only and write-broadcast protocols showed half the misses and server load of the polling protocol. The choice of write or fetch policy made a much smaller difference.

Available in PDF, EPUB and Kindle. Book excerpt: A key determinant of overall system performance and power dissipation is the cache hierarchy since access to off-chip memory consumes many more cycles and energy than on-chip accesses. In addition, multi-core processors are expected to place ever higher bandwidth demands on the memory system. All these issues make it important to avoid off-chip memory access by improving the efficiency of the on-chip cache. Future multi-core processors will have many large cache banks connected by a network and shared by many cores. Hence, many important problems must be solved: cache resources must be allocated across many cores, data must be placed in cache banks that are near the accessing core, and the most important data must be identified for retention. Finally, difficulties in scaling existing technologies require adapting to and exploiting new technology constraints. The book attempts a synthesis of recent cache research that has focused on innovations for multi-core processors. It is an excellent starting point for early-stage graduate students, researchers, and practitioners who wish to understand the landscape of recent cache research. The book is suitable as a reference for advanced computer architecture classes as well as for experienced researchers and VLSI engineers.
