Multigrain Shared Memory Multigrain Shared Memory
Parallel workstations, each comprising a 10-100 processor shared memory machine, promise cost-e ective general-purpose multiprocessing. This thesis explores the coupling of such smallto medium-scale shared memory multiprocessors through software over a local area network to synthesize larger shared memory systems. Multiprocessors built in this fashion are called Distributed Scalable Shared memo...
متن کاملMemory Network Shared Memory ( UMA ) Shared Memory ( NUMA )
Multiprocessors with shared memory are considered more general and easier to program than message-passing machines. The scalability is, however, in favor of the latter. There are a number of proposals showing how the poor scalability of shared memory multiprocessors can be improved by the introduction of private caches attached to the processors. These caches are kept consistent with each other...
متن کاملShared memory and distributed shared memory systems: A survey
Parallel and distributed processing did not lose their allure since their inception in 1960’s; the allure is in terms of their ability to meet a wide range of price and performance. However, in many cases these advantages were not realized due to longer design times, limited scalability, lack of OS and programming support, and the ever increasing performance/cost ratio of uniprocessors [Bell 99...
متن کاملShared Memory Multiprocessors
The most prevalent form of parallel architecture is the multiprocessor of small to moderate scale that provides a global physical address space and symmetric access to all of main memory from any processor, often called a symmetric multiprocessor or SMP Every processor has its own cache, and all the processors and memory modules attach to the same interconnect, which is usually a shared bus. SM...
متن کاملScalable Shared - Memory Architectures
Shared-memory multiprocessing is emerging as a popular approach to increase computing power, over that of sequential computing, while maintaining programmability. What makes the base shared-memory paradigm attractive is the simplicity of the programming model: all memory is in a pool and is globally shared. Furthermore, architectures that do not require a broadcast channel for interprocessor co...
