Granularity and communication overheads
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. 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 … 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 …

WebSources of overheads 1. Interprocess interaction: Any nontrivial parallel system requires its processing elements to interact and communicate data (e.g., intermediate results). The time spent communicating data between processing elements is usually the most significant source of parallel processing overhead. 2. Idling: flying a kite at night simpsonsWebDec 1, 1996 · The granularity of a parallel program can be defined as the average size of a sequential unit of computation in the program, with no inter-processor synchronizations or communications. A program will execute efficiently if its average run-time granular- ity is large compared to the overheads of process creation and communication. green library hoursWeb7.3 Communication Overhead Here we show that, depending on bandwidth, latency, and how summary information is communicated among the agents, delays due to communication overhead vary. ...
