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 ... WebIn parallel computing, granularity is a qualitative measure of the ratio of computation to communication. Periods of computation are typically separated from periods of communication by synchronization events.

WebQuestions : Granularity is. (a) In parallel computing, it is a qualitative measure of the ratio of computation to communication. (b) Here relatively small amounts of computational work are done between communication events. (c) Relatively large amounts of computational work are done between communication / synchronization events. 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. Fine-grained parallelism: Assume there are 100 processors … See more Granularity is closely tied to the level of processing. A program can be broken down into 4 levels of parallelism - 1.
