Given that programs exhibit quite different sharing patterns, providing only one or two fixed granularities cannot result in an efficient use of resources. On the other hand, supporting arbitrarily granularity sizes …

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 income tax act 81Webexample, in a simulation of a communication network, one would expect workstations on the same subnetsvork will interact much more frequently than workstations in different cities. our testbcd Tne Warp system was designed to efficiently exe-cute large-scale, small event granularity simulations as well as large event granularity applications. income tax act 80eeIn 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 is transferred among processors frequently in amounts of one or a few memory words. Coarse-grained is the opposite: data is communicated infrequently, after larger … income tax act 84 3Web(KPN) [3]. As the granularity of communications in the KPN is also relatively coarse, they do not address communication overhead due to fine-grain specification. Moreover, the coarse granularity of KPN may limit the design space.
