Controlling the granularity of automatic parallel programs

WebGranularity is a well known concept in parallel processing. While intuitively, the distinction between coarse-grain and fine-grain paralellism is clear, there is no rigorous definition. This paper develops two notions of granularity, each defined formally and represented by a single rational number. The two notions are compared and contrasted ... WebIn parallel computing, granularity [2] is a qualitative measure of the ratio of computation to communication. Periods of computation are typically separated from periods of communication by synchronization events. In Fine-Grain parallelism: relatively small amounts of computational work are done between communication events. ... WebLimits on Parallel Performance n It would appear that the parallel time can be made arbitrarily small by making the decomposition finer in granularity. n There is an inherent bound on how fine the granularity of a computation can be. For example, in the case of multiplying a dense matrix with a vector, there can be no can dogs take chaga
