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 is closely tied to the level of processing. A program can be broken down into 4 levels of parallelism - 1. Instruction … See more • Instruction-level parallelism • Data Parallelism 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 that are responsible for processing the 10*10 image. Ignoring the communication … 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
WebJan 26, 2024 · Load balance is an important issue in datacenter networks.
