This is done for the subdomains on each PE until one of the directions cannot be divided by 2 without rest. If this is the case, the coarsest grid level of each subdomain are gathered on PE0 for further coarsening. For gathering on PE0, at least one coarser grid level is needed on the subdomains. \\ |
