This book was released on 2012-12-06 with total page 202 pages. Available in PDF, EPUB and Kindle. 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 thesis proposes a two-level cache organization for multiprocessors. The first level of cache consists of a private cache per processor. The second level of caches is shared by all processors. The main memory is also similarly shared. A cache coherence solution is proposed for such an organization. The performance of the proposed multi-processor is evaluated with analytical methods. The factors that affect the performance are quantitatively discussed. A variation of the proposed coherence algorithm is presented to improve the performance. Keywords: High reliability; Cache memories; Mathematical analysis. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In this paper, we study a hardware-supported, compiler-directed (HSCD) cache coherence scheme, which can be implemented on a large-scale multiprocessor using off-the-shelf microprocessors, such as the Cray T3D. The scheme can be adapted to various cache organizations, including multi-word cache lines and byte-addressable architectures. Several system related issues, including critical sections, inter-thread communication, and task migration have also been addressed. The cost of the required hardware support is minimal and proportional to the cache size. The necessary compiler algorithms, including intra- and interprocedural array data flow analysis, have been implemented on the Polaris parallelizing compiler [33]. From our simulation study using the Perfect Club benchmarks [5], we found that in spite of the conservative analysis made by the compiler, the performance of the proposed HSCD scheme can be comparable to that of a full-map hardware directory scheme. Given its comparable performance and reduced hardware cost, the proposed scheme can be a viable alternative for large-scale multiprocessors such as the Cray T3D, which rely on users to maintain data coherence."

Book excerpt: Abstract: "In this paper, we present compiler algorithms for detecting references to stale data in shared-memory multiprocessors. The algorithm consists of two key analysis techniques, stale reference detection and locality preserving analysis. While the stale reference detection finds the memory reference patterns that may violate cache coherence, the locality preserving analysis minimizes the number of such stale references by analyzing both temporal and spatial reuses. By computing the regions referenced by arrays inside loops, we extend the previous scalar algorithms [8] for more precise analysis. We develop a full interprocedural array data-flow algorithm, which performs both bottom- up side-effect analysis and top-down context analysis on the procedure call graph to further exploit locality across procedure boundaries. The interprocedural algorithm eliminates cache invalidations at procedure boundaries, which were assumed in the previous compiler algorithms [9]. We have fully implemented the algorithm in the Polaris parallelizing compiler [27]. Using execution-driven simulations on Perfect Club benchmarks, we demonstrate how unnecessary cache misses can be eliminated by the automatic stale reference detection. The algorithm can be used to implement cache coherence in the shared-memory multiprocessors that do not have hardware directories, such as Cray T3D [20]."

Book excerpt: Cache And Interconnect Architectures In Multiprocessors Eilat, Israel May 25-261989 Michel Dubois UniversityofSouthernCalifornia Shreekant S. Thakkar SequentComputerSystems The aim of the workshop was to bring together researchers working on cache coherence protocols for shared-memory multiprocessors with various interconnect architectures. Shared-memory multiprocessors have become viable systems for many applications. Bus based shared-memory systems (Eg. Sequent's Symmetry, Encore's Multimax) are currently limited to 32 processors. The fIrst goal of the workshop was to learn about the performance ofapplications on current cache-based systems. The second goal was to learn about new network architectures and protocols for future scalable systems. These protocols and interconnects would allow shared-memory architectures to scale beyond current imitations. The workshop had 20 speakers who talked about their current research. The discussions were lively and cordial enough to keep the participants away from the wonderful sand and sun for two days. The participants got to know each other well and were able to share their thoughts in an informal manner. The workshop was organized into several sessions. The summary of each session is described below. This book presents revisions of some of the papers presented at the workshop.

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.

Available in PDF, EPUB and Kindle. Book excerpt: As it becomes increasingly difficult to improve the performance of a microprocessor by simply increasing its clock speed, chip makers are looking towards parallelism in the form of Chip Multiprocessors (CMPs) to increase performance. Indeed, recent research at Intel suggests that chips with hundreds of cores are possible in the not-so-distant future. As the number of cores grows, so does the size of the cache systems required to allow them to operate efficiently. Caches have grown to consume a significant percentage of the power utilized by a processor. In this research, we extend the concept of a location cache to support CMP systems in combination with low-power L2 caches based upon the gated-ground technique. The combination of these two techniques allows for reductions in both dynamic and leakage power consumption. In this work we will present an analysis of the power savings provided by utilizing location caches in a CMP system. The performance of the cache system is evaluated by extending the capability of CACTI and Simics using the SPLASH-2 and ALPBench benchmark suites. These simulation results demonstrate that the utilization of location caches in CMP systems is capable of saving a significant amount of power over equivalent CMP systems that lack location caches.

This book was released on 1993 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "As VLSI technology improvements continue to widen the gap between processor and main memory cycle times, cache performance becomes increasingly important to overall system performance. Cache memories help alleviate the cycle time disparity, but only for programs that exhibit sufficient spatial and temporal locality. Programs with unruly access patterns spend much of their time transferring data to and from the cache. To fully exploit the performance potential of fast processors, programmers must explicitly consider cache behavior, restructuring their codes to increase locality. As these fast processors proliferate, techniques for improving cache performance must move beyond the supercomputer and multiprocessor communities and into the mainstream of computing. In this paper, we examine some of the techniques that programmers can use to improve cache performance. We show how to use CPROF, a cache profiler, to identify cache performance bottlenecks and gain insight into their origin. This insight helps programmers understand which of the well-known program transformations are likely to improve cache performance. Using CPROF and a 'cookbook' of simple transformations, we show how to tune the cache performance of six of the SPEC92 benchmarks. By restructuring the source code, we greatly improve cache behavior and achieve execution time speedups ranging from 1.06 to 1.81 on a DECstation 5000/125."
