public class UseCase3

extends UseCase

In this use case, localData has length d on each proc, except for proc0, which has localData with length d*nProcs. In the original configuration of the data, only the first d elements in localData on proc 0 are used, the rest of the elements in procData are filled with the string "-". Hence in the beginning we are essentially using d elements on each proc, and the d*nProcs data elements are the distinct integers 0,1,...,d*nProcs-1 arranged in the dictionary order.

The map sends all the data on all the procs with positive to rank to proc 0, filling in the "blank" spots on proc 0.

Field Summary

(package private) int	d The length of localData on all procs with positive rank
