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.
Book Synopsis A Primer on Memory Consistency and Cache Coherence by : Daniel Sorin
Download or read book A Primer on Memory Consistency and Cache Coherence written by Daniel Sorin and published by Morgan & Claypool Publishers. 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.

Book Synopsis Visible Synchronization Based Cache Coherence by : Krishna Kumar

Available in PDF, EPUB and Kindle. Book excerpt: In large scale machines, thousands of processor cycles, in other words, missed opportunities to issue floating point instructions, may be lost while waiting for a high latency synchronization or memory operation to complete, or a stall in an instruction pipeline to be dealt with. Latency is avoided by bringing data to a nearby locale for future reference (e.g., caching) while latency is tolerated by overlapping data movement with something useful. The issue of cache coherence arises whenever there are multiple copies of a shared datum in different caches of a shared-memory multiprocessor system. It is in order to maintain consistency between these multiple copies that cache coherence protocols are employed. The efficiency of latency avoidance methods is largely dependent upon the minimization of coherence traffic in the coherence protocol used to maintain cache coherency. Cache coherence protocols in general can be divided into two classes: hardware implemented ones and compiler implemented ones. Hardware implemented ones lead to large coherence traffic, and large state storage space. Conventional compiler implemented ones involve indiscriminate wasteful invalidation. There is also redundancy between synchronization operations and coherence operations. We seek to eliminate both weaknesses, by letting visible synchronization directly coordinate changes in the writability of shared data. We propose to add scalable compiler managed caches to a TERA-like multithreaded multiprocessor architecture, with user/compiler knowledge (i.e., alias analysis, dependence analysis and user directives) used to eliminate essentially all coherence traffic. To preserve scalability, we aim to use latency tolerance methods like switch-on-every-cycle multithreading, and augment this with simple, low-latency cache coherence protocols such as our visible synchronization based one.

This book was released on 2006 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this thesis is twofold. The first objective is to provide generic methodologies for enabling efficient communication among heterogeneous processors in multiprocessor system-on-a-chips (MPSoCs). The second objective is to evaluate the coherence traffic efficiency based on a novel emulation platform using FPGA.
Book Synopsis Design and Analysis of Update-Based Cache Coherence Protocols for Scalable Shared-Memory Multiprocessors by : David Brian Glasco

This book was released on 1994 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overall, this work demonstrates that update-based protocols can be used not only as a coherence mechanism, but also as a latency reducing and tolerating technique to improve the performance of a set of fine-grain scientific applications. But as with other latency reducing techniques, such as data prefetch, the technique must be used with an understanding of its consequences.

Book Synopsis Efficient Analysis of Caching Systems by : James Gordon Thompson
Download or read book Efficient Analysis of Caching Systems written by James Gordon Thompson and published by . This book was released on 1987 with total page 526 pages. 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.
