+ \basis repartitioning & \textbf{bool} & [0] & En/disables
+ repartitioning of the macro mesh, when derivation of mean number of
+ DOFs exceeds a threshold value. \\\hline
+
+ \basis repartition ith change & \textbf{int} & [20] & Sets number of
+ mesh changes to wait before threshold check for repartitioning will
+ be performed.\\\hline
+
+ \basis partitioner & \textbf{enum}\{parmetis, zoltan, simple\} &
+ [parmetis] & Defines the external tool that performs the
+ partitioning of the, e.g.~by graph-partitioning. {\em simple} does
+ not change the initial partitioning, i.e., its a random distribution
+ of the macro elements to the processors.\\\hline
+
+ \basis box partitioning & \textbf{bool} & [0] & If the macro mesh is
+ globally refined from macro.stand.2d or macro.stand.3d, than the
+ partitioner may compute the partitioning not based on triangled or
+ tetrahedron, but on (composed) rectangles or boxes. Till now this is
+ implemented only for 3D and Zoltan partitioner. \\\hline
+
+ \basis log main rank & \textbf{bool} & [0] & If set to {\em true},
+ stdout output will be printed only by the main rank 0. Otherwise,
+ all ranks stdout output will be created. \\\hline
+
+ \basis pre refine & \textbf{int} & [-1] & If set to -1, the number
+ of pre refinements for the macro mesh will be calculated for the
+ given number of processors. This value can be overwritten by setting
+ a value $>= 0$. \\\hline
+
+ \basis output->serialization filename & \textbf{string} & [] & Name
+ of the parallel serialization file. If at least one stationary
+ problem is serialized, this parameter must be set. \\\hline
+
+ \basis input->serialization filename & \textbf{string} & [] & Name
+ of the parallel deserialization file. If at least one stationary
+ problem is deserialized, this parameter must be set. \\\hline
+
+ \basis debug output dir & \textbf{string} & [] & Path name where
+ debug data should be written to. \\\hline
+
+ \basis write parallel debug file & \textbf{bool} & [0] & If set to
+ {\em true}, the parallelization will create for each rank a file
+ with the name ``mpi-dbg-\{rank-no\}.dat''. This files contain
+ information about all DOF indices in ranks domain. They may be
+ useful for debugging or some postprocessing steps. \\\hline
