Detailed Description

Function Documentation

hasMETIS()

bool apf::hasMETIS

(

)

#include <metis/apfMETIS.h>

Query whether METIS is supported.

Support for METIS may or may not be included during compilation. This function allows users to check whether the APF-METIS routines will succeed. If this function returns false, all APF-METIS functions will fail.

Returns

true if APF-METIS is compiled with METIS support

makeMETISbalancer()

Balancer* apf::makeMETISbalancer

(

Mesh *

mesh

)

#include <metis/apfMETIS.h>

Make an apf::Balancer that calls METIS for the underlying algorithm.

The necessary graph information is localized to rank 0 from mesh topology, METIS is run serially, then the 'migration plan' is sent to the remaining N-1 processes.

Parameters

mesh	the apf::Mesh to balance

Returns

an apf::Balancer object

makeMETISsplitter()

Splitter* apf::makeMETISsplitter

(

Mesh *

mesh

)

#include <metis/apfMETIS.h>

Make an apf::Splitter that calls METIS for the underlying algorithm.

Parameters

mesh	the apf::Mesh to split

Returns

an apf::Splitter object
