The difference of the data transfer are compared
in Fig.9. In total, DMNS cost the least data transfer among
the three methods. It seems that the data transfer cost among
the first level is much larger than that of the left levels. Data
transfer for normal distribution input is larger than a uniform
distribution input. The data transfer of the level 2-n for normal
distribution input is almost the same with that for uniform
distribution input, when compared to the data transfer of the
first level. HSA based on DMNS show the best performance
among the three methods, which cost the least data transfer
when the number of the nodes in the Switch is 32 and 64. All
three method cost almost the same data transfer of the level
2-n, when the number of the nodes in the Switch is 128 and
256. For each scheduling method, the larger the number of
nodes in the Switch is, the less data transfer of the level 2-n
