    5757and the {{{wrf4g_submitter.sh}}} will setup 365 independent runs performing the 7-day forecasts which will be distributed in the grid or in your local cluster.

     59=== Multipleparameters runs ===
     60Multi-physics runs are activated when the {{{multiple_paramters}}} parameter is set to one. Three additional parameters allow you to configure the physics combinations to set up.
     61
     62This mode allows varying parameters in general, not necessarily physics options. For instance, if user would like to check WRF performance on domain MPI-decomposition, by settting:
     63
     64  {{{
     65is_multiphysics = 1
     66  multiphysics_variables = "nproc_x,nproc_y"
     67  multiphysics_nitems = "1,1"
     68  multiphysics_combinations = "1,4/4,1/2,2/-1,-1"
     69  }}}
     70you can vary the domain decomposition and send an experiment with four realizations and the only difference is the way the MPI domains are partitioned.
