public class UseCase0

extends UseCase

In this use case, localData has length d on each proc. The d*nProcs data elements are the distinct integers 0,1,...,d*nProcs-1 arranged in the dictionary order. Then the data are permuted by sending each element to the corresponding position in the next proc, where we cycle around the procs.

Field Summary

(package private) int	d The length of the localData array on each proc.
(package private) int	nData The total amount of data, i.e., d*nProcs.
