WebThe parallel unit of execution simply refers to the amount of independent work done by each executing thread. In discussion of parallel computing, granularity is a measure of the … 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.

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 ...
