Granularity parallel computing
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 … See more Granularity is closely tied to the level of processing. A program can be broken down into 4 levels of parallelism - 1. Instruction level. 2. Loop level 3. Sub-routine level and See more • Instruction-level parallelism • Data Parallelism See more WebFeb 5, 2024 · In parallel computing, the granularity of computations of an algorithm is a measure of the amount of computation which is conducted by that task . Typically, the parallelism of a program can be classified into two categories: fine-grained and coarse-grained. In a fine-grained parallel algorithm, a program is broken down to a large …

WebJan 31, 2024 · An encyclopedia article sourced from Wikipedia. When working with parallel computing, the degree of granularity (or grain size) of a task indicates how much work (or computation) is performed. In addition, granularity can also be defined as the overhead involved in communicating between multiple processors. WebImprovements in computing performance can be achieved at levels ranging from the stages of instruction execution to sharing the processing load across multip...

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.
