granularity

[‚gran·yə′lar·əd·ē]
(graphic arts)
The distribution of grains in a portion of photographic material that has been uniformly exposed and processed.
(petrology)
The feature of rock texture relating to the size of the constituent grains or crystals.
(systems engineering)
The degree to which a system can be broken down into separate components, making it customizable and flexible.

granularity

(jargon, parallel)
The size of the units of code under consideration in some context. The term generally refers to the level of detail at which code is considered, e.g. "You can specify the granularity for this profiling tool".

The most common computing use is in parallelism where "fine grain parallelism" means individual tasks are relatively small in terms of code size and execution time, "coarse grain" is the opposite. You talk about the "granularity" of the parallelism.

The smaller the granularity, the greater the potential for parallelism and hence speed-up but the greater the overheads of synchronisation and communication.

granularity

The degree of modularity of a system. More granularity implies more flexibility in customizing a system, because there are more, smaller increments (granules) from which to choose.

The hardware scale increment becomes much more significant if more number of switching bands per fiber (finer GRE granularity) is applied.
In this experiment, we proceed to study the effect of the segmentation granularity for the BIST-JOIN method in which the segmentation granularities are 4 x 4 x 4, 8 x 8 x 8, 16 x 16 x 16, 32 x 32 x 32, 64 x 64 x 64, and 128 x 128 x 128, respectively.
The diagnosis was supported by the presence of key features of foveal granularity and disruption of the ellipsoid zone on OCT and their correlation with the hyperautofluorescent lesions identified on BAF.

Although research on classification is quite mature, resources classification based on granularity in social network is still in early stages; hence, it is an open problem for research.
First of all, the establishment of travel mode choice factors evaluation system, and carries on the attribute reduction, improve the efficiency of the next cluster; secondly, construct the homogeneous travel fuzzy similarity matrix, and calculate the dynamic cluster analysis; finally, according to the operation strategy of bus companies choose different strategies, adjusted in different level of granularity and get the final clustering result.
