Abstract:
The benefits of hardware support for shared memory versus those for message passing are difficult to evaluate without an in-depth study of real applications on a common platform. We evaluate the communication mechanisms of the MIT Alewife machine, a multiprocessor which provides integrated cache-coherent shared memory, massage passing, and DMA. We perform this evaluation with "best-effort" implementations which solve several sparse, irregular benchmark problems with a preconditioned conjugate gradient sparse matrix solver (ICCG). We find that machines with fast global memory operations do not

The advancement of modern processors with many-core and large-cache may have little computational advantages if only serial computing is employed. In this study, several parallel computing approaches, using devices with multiple or many processor cores, and graphics processing units are applied and compared to illustrate the potential applications in fluid-film lubrication study. Two Reynolds equations and an air bearing optimum design are solved using three parallel computing paradigms, OpenMP, Compute Unified Device Architecture, and OpenACC, on standalone shared-memory computers.

Abstract:
This note presents some experiments on different clusters of SMPs, where both distributed and shared memory parallel programming paradigms can be naturally combined. Although the platforms exhibit the same macroscopic memory organization, it appears that their individual overall performance is closely dependent on the ability of their hardware to efficiently exploit the local shared memory within the nodes. In that context, cache blocking strategy appears to be very important not only to get good performance out of each individual processor but mainly good performance out of the overall comput

Sizes of on-chip caches on current commercial microprocessors range from 16 Kbytes to 36 Kbytes. These microprocessors can be directly used in the design of a low cost single-bus shared memory multiprocessors without using any second-level cache. In this paper, we explore the viability of such a multi-microprocessor. Simulations results clearly establish that performance of such a system will be quite poor if on-chip caches are direct-mapped. On the other hand, when the on-chip caches are partially associative, the achieved level of performance is quite promising. In particular, two recently p

Several studies point out the benefits of a shared L2 cache, but some other properties of shared caches must be considered to lead to a thorough understanding of all chip multiprocessor (CMP) bottlenecks. Our paper evaluates and explains shared cache bottlenecks, which are very important considering the rise of many-core processors. The results of our simulations with 32 cores show low performance when L2 cache memory is shared between 2 or 4 cores. In these two cases, the increase of L2 cache latency and contention are the main causes responsible for the increase of execution time.

Aiming at examining the problems of the low cache hit ratio and high-average routing hops in named data networking (NDN), this paper proposes a cache-optimization strategy based on dynamic popularity and replacement value. When the requested content arrives at the routing node, the latest popularity is calculated based on the number of requests in the current cycle and the popularity of the previous cycle. We adjust the node cache threshold according to the occupation of the node cache space and cache the content with a higher popularity than the threshold. When the cache is complete, the cach

The thesis explores the sources of energy inefficiency in asymmetric multi- core architectures where energy efficiency is measured by the energy-delay squared product. The insights gathered from this study drive the development of optimized thread scheduling and coordinated cache management strategies in an important class of asymmetric shared memory architectures.

A cache is a high speed memory located between processors and main memory to fill the speed gap between them. In a loosely coupled parallel computer, each processor has its own cache memory. The processor accesses information from its cache memory, which stores information obtained from the main memory through an interconnection network. A major challenge in this system is to keep the data in all the caches consistent with that in main memory. This is referred to as the cache coherence problem. One solution is to have a bus between the caches, and supply each cache with a controller which list

The corresponding operational definitions are given, which are based on the use of the LRU stack distances. The proposed model is called a deterministic 3C model or D3C.
