An Adaptive Sharing Framework for Efficient Multi-source

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.
