     60893d-data from a precursor run are read by the initial (main) run. The
     6090precursor run is allowed to have a smaller domain along x and y
     6091compared with the main run. Also, different numbers of processors can
     6092be used for these two runs. Limitations are that the precursor run must
     6093use cyclic horizontal boundary conditions and that the subdomains of
     6094the main run must not be larger than the subdomains of the precursor
     6095run. If the total domain of the main run is larger than that of the precursor
     6096run, the domain is filled by cyclic repetition&nbsp;of the (cyclic)
     6097precursor data. This initialization method is recommended if a
     6098turbulent inflow is used (see <a href="chapter_4.1.html#turbulent_inflow">turbulent_inflow</a>). 3d-data must be made available to the run by activating an appropriate file connection statement for local file BININ.

    7889 option <a href="http://www.muk.uni-hannover.de/software/mrun_beschreibung.html#Opt-X">-X</a>.
    7890 By default, depending on the type of the parallel computer, PALM
    7891 generates a 1d processor
    7892 net (domain decomposition along x, <span style="font-weight: bold;">npey</span>
    7893 = <span style="font-style: italic;">1</span>) or a
    7894 2d-net (this is
    7895 favored on machines with fast communication network). In case of a
    7896 2d-net, it is tried to make it more or less square-shaped. If, for
    7897 example, 16 processors are assigned (-X 16), a 4 * 4 processor net is
    7898 generated (<span style="font-weight: bold;">npex</span>
    7899 = <span style="font-style: italic;">4</span>, <span style="font-weight: bold;">npey</span>
    7900 = <span style="font-style: italic;">4</span>).
    7901 This choice is optimal for square total domains (<a href="#nx">nx</a>
    7902 = <a href="#ny">ny</a>),
    7903 since then the number of ghost points at the lateral boundarys of
    7904 the subdomains is minimal. If <span style="font-weight: bold;">nx</span>
    7905 nd <span style="font-weight: bold;">ny</span>
    7906 differ extremely, the
    7907 processor net should be manually adjusted using adequate values for <span style="font-weight: bold;">npex</span> and <span style="font-weight: bold;">npey</span>.&nbsp; </p>

     5828option <a href="http://www.muk.uni-hannover.de/software/mrun_beschreibung.html#Opt-X">-X</a>.
     5829By default, depending on the type of the parallel computer, PALM
     5830generates a 1d processor
     5831net (domain decomposition along x, <span style="font-weight: bold;">npey</span>
     5832= <span style="font-style: italic;">1</span>) or a
     58332d-net (this is
     5834favored on machines with fast communication network and/or large number of processors (&gt;256)). In case of a
     58352d-net, it is tried to make it more or less square-shaped. If, for
     5836example, 16 processors are assigned (-X 16), a 4 * 4 processor net is
     5837generated (<span style="font-weight: bold;">npex</span>
     5838= <span style="font-style: italic;">4</span>, <span style="font-weight: bold;">npey</span>
     5839= <span style="font-style: italic;">4</span>).
     5840This choice is optimal for square total domains (<a href="chapter_4.1.html#nx">nx</a>
     5841= <a href="chapter_4.1.html#ny">ny</a>),
     5842since then the number of ghost points at the lateral boundarys of
     5843the subdomains reaches a minimum. If <span style="font-weight: bold;">nx</span>
     5844and <span style="font-weight: bold;">ny</span>
     5845differ extremely, the
     5846processor net should be manually adjusted using adequate values for <span style="font-weight: bold;">npex</span> and <span style="font-weight: bold;">npey</span>.&nbsp; </p>
