Book excerpt: We present a study that accentuates the performance and scalability aspects of directory-based cache coherence in multiprocessor systems. Using a multiprocessor with a software-based coherence scheme, efficient implementations rely heavily on the programmer's ability to explicitly manage the memory system, which is typically handled by hardware support on other bus-based, shared memory multiprocessors. We describe a scalable, shared memory, cache coherent multiprocessor and present simulation results obtained on three parallel programs. This multiprocessor configuration exhibits high performance at no additional parallel programming cost.

This book was released on 2010-02 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chip multiprocessors (CMPs) constitute the new trend for increasing the performance of future computers. In the near future, chips with tens of cores will become more popular. Nowadays, directory-based protocols constitute the best alternative to keep cache coherence in large-scale systems. Nevertheless, directory-based protocols have two important issues that prevent them from achieving better scalability: the directory memory overhead and the long cache miss latencies. This book focuses on these key issues. The first proposal is a scalable distributed directory organization that copes with the memory overhead of directory-based protocols. The second proposal presents the direct coherence protocols, which are aimed at avoiding the indirection problem of traditional directory-based protocols and, therefore, they improve applications' performance. Finally, a novel mapping policy for distributed caches is presented. This policy reduces the long access latency while lessening the number of off-chip accesses, leading to improvements in applications' execution time.

This book was released on 2012-12-06 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: The workshop on Scalable Shared Memory Multiprocessors took place on May 26 and 27 1990 at the Stouffer Madison Hotel in Seattle, Washington as a prelude to the 1990 International Symposium on Computer Architecture. About 100 participants listened for two days to the presentations of 22 invited The motivation for this workshop was to speakers, from academia and industry. promote the free exchange of ideas among researchers working on shared-memory multiprocessor architectures. There was ample opportunity to argue with speakers, and certainly participants did not refrain a bit from doing so. Clearly, the problem of scalability in shared-memory multiprocessors is still a wide-open question. We were even unable to agree on a definition of "scalability". Authors had more than six months to prepare their manuscript, and therefore the papers included in this proceedings are refinements of the speakers' presentations, based on the criticisms received at the workshop. As a result, 17 authors contributed to these proceedings. We wish to thank them for their diligence and care. The contributions in these proceedings can be partitioned into four categories 1. Access Order and Synchronization 2. Performance 3. Cache Protocols and Architectures 4. Distributed Shared Memory Particular topics on which new ideas and results are presented in these proceedings include: efficient schemes for combining networks, formal specification of shared memory models, correctness of trace-driven simulations,synchronization, various coherence protocols, .

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: 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: Abstract: "Efficiently maintaining cache coherence is a major problem in large-scale shared memory multiprocessors. Hardware directory schemes have very high memory requirements, while software-directed schemes must rely on imprecise compile-time memory disambiguation. Recently proposed dynamic directory schemes allocate pointers to blocks only as they are referenced, which significantly reduces their memory requirements, but they still allocate pointers to blocks that do not need them. We show how compiler marking can further reduce the directory size by allocating pointers only when necessary. Using trace-driven simulations, we find that the performance of this new approach is comparable to other coherence schemes, but with significantly lower memory requirements."
