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 Web5.1.2.2 Increase granularity of frequency-domain resource allocation. The granularity size is determined mainly based on the signaling overhead and the complexity of resource …

WebJan 13, 2011 · Partitioning Granularity, Communication Overhead, and Adaptation in OS Services for Distributed Reconfigurable Systems on Chip January 2011 DOI: … WebProviding an arbitrarily variable granularity increases hardware and/or software overheads. Moreover, its efficient implementation requires the user to provide some information on the granularity, sacrificing the programmability of the shared memory paradigm.
