    41 {{{name}}} is the domain name given by the user. {{{id}}} is the number of the domain (can be arbitrarily chosen, but it would be good practise to number the domains in ascending order starting with 1), while {{{parent_id}}} gives the number of the domain in which this domain is embedded. The so-called ''root''-domain which includes all other ''nested''-domains should have the id 1. The ''root''-domain has no ''parent''-domain and must be given ''-1'' as its {{{parent_id}}}. {{{npe_x}}} and {{{npe_y}}} are the number of PEs to be used along x and y for this domain (i.e. the virtual PE-grid of the domain). {{{lower_left_x}}} and {{{lower_left_y}}} are the coordinates in m of the south-left scalar (?) gridpoint of the domain. The ''root''-domain has {{{lower_left_x}}} = ''0.0'' and {{{lower_left_y}}} = ''0.0''. A ''nested''-domain must be completely embedded in its ''parent''-domain. \\\\

    4241The following gives an example for defining a single nested-domain embedded in a root-domain:

    47 The total number of MPI-processes required by this configuration is 4*4 + 4*4 = 32.
     46The total number of MPI-processes required by this configuration is 16 + 16 = 32.
