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.

Center for Supercomputing Research and Development and published by . This book was released on 1992 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Memory access time is a key factor limiting the performance of large-scale, shared-memory multiprocessors. In such systems, limited bandwidth in the interconnection between the processors and the memories, coupled with long delays resulting from network and memory conflicts, can produce serious memory access delays. Incorporating memory hierarchies and asynchronous block transfer mechanisms are common methods for reducing these delays. However, for these two mechanisms to be wed advantageously, they must be managed effectively, either in hardware or in software. Although this memory management problem is becoming increasingly important, good techniques are still lacking. The problem of reducing memory access delays can be attacked at several levels. The first is to attempt to improve the performance of the shared-memory system itself, where the shared-memory system includes implicitly both the network and the memory modules themselves. The second is to develop techniques to manage the memory hierarchy more effectively and to make use of the block transfer mechanisms. This thesis addresses this problem at both of these levels. The first part examines the behavior of a realistic shared-memory system and evaluates cost-effective hardware modifications for improving this balance. An additional goal is to achieve memory system scalability, where the term scalable describes systems whose per-processor performance is roughly constant across the range of system sizes examined. The remainder of this thesis addresses the problem of improving utilization of local storage in shared-memory systems where, at the very least, each processor has access to local (private) storage in addition to the global (shared) memory. A combined flow-and-dependence analysis algorithm is developed which produces the analytical information needed to optimize data accesses. It is shown how this information can be used as part of an intergrated hardware/software approach to eliminating redundant (unnecessary) memory accesses and prefetching data.

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we have focused on addressing interference at the shared memory-hierarchy resources: last level cache and off-chip memory access in the context of large-scale multicore systems. Towards this end, the first work focused on shared last level caches, where the number of applications sharing the cache could exceed the associativity of the cache. To manage caches in such situations, our solution estimates the cache footprint of applications to approximate how well they could utilize the cache. Quantitative estimate of cache utility explicitly allows enforcing different priorities across applications. The second part brings in prefetch awareness in cache management. In particular, we observe prefetched cache blocks to exhibit good reuse behavior in the context of larger caches. Our third work focuses on addressing interference between on-demand and prefetch requests at the shared off-chip memory access. This work is based on two fundamental observations of the fraction of prefetch requests generated and its correlation with prefetch usefulness and prefetcher-caused interference. Altogether, two observations lead to control the flow of prefetch requests between LLC and off-chip memory.

This book was released on 1990 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "An adaptive cache coherence mechanism exploits semantic information about the expected or observed access behavior of particular data objects. We contend that, in distributed shared memory systems, adaptive cache coherence mechanisms will outperform static cache coherence mechanisms. We have examined the sharing and synchronization behavior of a variety of shared memory parallel programs. We have found that the access patterns of a large percentage of shared data objects fall in a small number of categories for which efficient software coherence mechanisms exist. In addition, we have performed a simulation study that provides two examples of how an adaptive caching mechanism can take advantage of semantic information."

This book was released on 2011-03-02 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many modern computer systems and most multicore chips (chip multiprocessors) support shared memory in hardware. In a shared memory system, each of the processor cores may read and write to a single shared address space. For a shared memory machine, the memory consistency model defines the architecturally visible behavior of its memory system. Consistency definitions provide rules about loads and stores (or memory reads and writes) and how they act upon memory. As part of supporting a memory consistency model, many machines also provide cache coherence protocols that ensure that multiple cached copies of data are kept up-to-date. The goal of this primer is to provide readers with a basic understanding of consistency and coherence. This understanding includes both the issues that must be solved as well as a variety of solutions. We present both highlevel concepts as well as specific, concrete examples from real-world systems.
