Granularity in parallel computing
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 ... WebGranularity in Parallel Computing. Improvements in computing performance can be achieved at levels ranging from the stages of instruction execution to sharing the …

Starting from recursive, task parallel programs, our compiler generates multiple … WebComputational Granularity. In parallel computing, granularity is a quantitative or qualitative measure of the ratio of computation to communication. Coarse: relatively large amounts of computational work …
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. ... 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 ...
WebIntroduction to Parallel Computing 9 Granularity •Numberand size of tasks. • Fine-grained: many small tasks. • Coarse-grained: few large tasks. • Related: degree of concurrency. (Nb. of tasks executable in parallel). • Maximal degree of concurrency. • Average degree of concurrency. •Previous matrix*vector fine-grained. In parallel computing, granularity (or grain size) of a task is a measure of the amount of work (or computation) which is performed by that task. Another definition of granularity takes into account the communication overhead between multiple processors or processing elements. It defines granularity as the … See more Depending on the amount of work which is performed by a parallel task, parallelism can be classified into three categories: fine-grained, medium-grained and coarse-grained parallelism. Fine-grained … See more Granularity affects the performance of parallel computers. Using fine grains or small tasks results in more parallelism and hence increases the speedup. However, synchronization overhead, scheduling strategies etc. can negatively impact the performance of fine … See more Consider a 10*10 image that needs to be processed, given that, processing of the 100 pixels is independent of each other.
