+If the degree of parallelism is 16, for 32-node systems, adaptive segmentation can use two
16-node virtual segments to execute queries that 
 do not require a degree of parallelism of 32.  This default setting can, for example, be
changed to 8 for a 16-node system, 
 to allow adaptive segmentation to leverage a lower degree of parallelism.
