Granularity in parallel computing
WebNov 27, 2011 · In computing. In parallel computing, granularity means the amount of computation in relation to communication, i.e., the ratio of computation to the amount of communication. Fine-grained parallelism means individual tasks are relatively small in terms of code size and execution time. The data are transferred among processors frequently in ... WebGranularity, and Communication In general, if the granularity of a decomposition is finer, the associated overhead (as a ratio of useful work associated with a task) increases. …

WebLimits on Parallel Performance It would appear that the parallel time can be made arbitrarily small by making the decomposition ner in granularity. There is an inherent bound on how ne the granularity of a computation can be. For example, in the case of multiplying a dense matrix with a vector, there can be no more than (n2) concurrent tasks. WebThe parallel unit of execution simply refers to the amount of independent work done by each executing thread. In discussion of parallel computing, granularity is a measure of the …
WebIn parallel computing, granularity is a measure of the ratio of computation to communication. Periods of computation are typically separated from periods of … WebParallel computing is an evolution of serial computing that attempts to emulate what has always been the state of affairs in the natural world: many complex, interrelated events happening at the same time, yet within a sequence. Some examples: Planetary and galactic orbits. Weather and ocean patterns.
