Detailed Description

creates the parallel topology from a given topology type and a number of processes

This class creates the parallel topology from a given topology type and a number of processes (typically read from a configuration). assuming ParallelTopologyType = XYZ and there is a cubic domain, splitted into 8 sub-domains (2 sub-domains in each dimension). Then the ordring of the MPI processes is: Rank=0 for x=0,y=0,z=0. Rank=1 for x=0,y=0,z=1. Rank=2 for x=0,y=1,z=0. Rank=3 for x=0,1=0,z=1. Rank=4 for x=1,y=0,z=0. Rank=5 for x=1,y=0,z=1. Rank=6 for x=1,y=1,z=0. Rank=7 for x=1,y=1,z=1.
