Module metis::option

Fine-tuning parameter types.

For options that take an integer value, should this value be negative, the default will be used, if any.

Structs

• CCOrder
  Specifies if the connected components of the graph should first be identified and ordered separately.
• Compress
  Specifies that the graph should be compressed by combining vertices that have identical adjacency lists.
• Contig
  Specifies that the partitioning routines should try to produce partitions that are contiguous.
• DbgLvl
  Specifies the amount of progress/debugging information will be printed during the execution of the algorithms.
• MinConn
  Specifies that the partitioning routines should try to minimize the maximum degree of the subdomain graph.
• NCuts
  Specifies the number of different partitions that it will compute. The final partition is the one that achieves the best edge cut or communication volume. Default is 1.
• NIter
  Specifies the number of iterations for the refinement algorithms at each stage of the uncoarsening process.
• NSeps
  Specifies the number of different separators that it will compute at each level of nested dissection.
• No2Hop
  Specifies that the coarsening will not perform any 2-hop matching when the standards matching approach fails to sufficiently coarsen the graph.
• PFactor
  Specifies the minimum degree of the vertices that will be ordered last.
• Seed
  Specifies the seed for the random number generator.
• UFactor
  Specifies the maximum allowed load imbalance among the partitions.

Enums

• CType
  Specifies the matching scheme to be used during coarsening.
• IpType
  Determines the algorithm used during initial partitioning.
• ObjType
  Specifies the type of objective.
• PType
  Specifies the partitioning method.
• RType
  Determines the algorithm used for refinement.

Traits

• Opt
  Trait implemented by METIS’ options.
