WebA central parameter that needs to be controlled to ensure efficient execution of task-parallel programs is the granularity of tasks. When they are too coarse-grained, scalability and load balance suffer, while very fine-grained tasks introduce execution overheads. We present a combined compiler and runtime approach that enables automatic ... 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.

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 ...
