SYNOPSIS

       ndmetis [options] <filename>

DESCRIPTION

              Required parameters

       filename
              Stores the graph to be partitioned.

              Optional parameters

       -ctype=string

              Specifies  the  scheme  to  be  used  to match the vertices of the graph during the
              coarsening.  The possible values are:

       rm     - Random matching

       shem   - Sorted heavy-edge matching [default]

       -iptype=string [applies only when -ptype=rb]

              Specifies the scheme to be used to compute the initial bisection of the graph.  The
              possible values are:

       edge   - Separator from an edge cut

       node   - Separator from a greedy node-based strategy [default]

       -rtype=string

              Specifies the scheme to be used for refinement.  The possible values are:

       1sided
              - 1-sided node-based refinement [default]

       2sided - 2-sided node-based refinement

       -ufactor=int

              Specifies  the maximum allowed load imbalance between the left and right partitions
              during each bisection. The  load  imbalanced  is  measured  as  the  ratio  of  the
              2*max(left,right)/(left+right),   where  left  and  right  are  the  sizes  of  the
              respective partitions.  A value of x indicates that the allowed load  imbalance  is
              1+x/1000.  Default is 200, indicating a load imbalance of 1.20.

       -pfactor=int

              Specifies  the  minimum  degree  of  the vertices that will be ordered last. If the
              specified value is x>0, then any vertices with a degree greater than 0.1*x*(average
              degree)  are  removed  from  the  graph, an ordering of the rest of the vertices is
              computed, and an overall ordering is computed by ordering the removed  vertices  at
              the  end  of the overall ordering.  Default value is 0, indicating that no vertices
              are removed

       -no2hop

              Specifies that the coarsening  will  not  perform  any  2-hop  matchings  when  the
              standard matching fails to sufficiently contract the graph.

       -nocompress

              Specifies  that  the  graph should not be compressed by combining together vertices
              that have identical adjacency lists.

       -ccorder

              Specifies if the connected components of the graph should first be  identified  and
              ordered separately.

       -niter=int

              Specifies  the  maximum  number of iterations for the refinement algorithms at each
              stage of the uncoarsening process. Default is 10.

       -nseps=int

              Specifies the number of different separators that it will compute at each level  of
              the  nested  dissection.  The  final  separator  that  is used is the smallest one.
              Default is 1.

       -nooutput

              Specifies that no ordering file should be generated.

       -seed=int

              Selects the seed of the random number generator.

       -dbglvl=int

              Selects the dbglvl.

       -help

              Prints this message.
