◆ Action

enum INMOST::Partitioner::Action

Enumerator
Partition	Partition "from scratch", not taking into account the current mesh distribution.
Repartition	Repartition the existing partition but try to stay close to the current mesh distribution.
Refine	Refine the current partition assuming only small changes of mesh distribution.

Member Function Documentation

◆ Evaluate()

void INMOST::Partitioner::Evaluate ( )

Evaluate the earlier specified partitioner.

See also: Partitioner::SetMethod

◆ Finalize()

static void INMOST::Partitioner::Finalize ( )

static

Finalize the use of partitioner.

See also: Partitioner::Initialize

◆ Initialize()

static void INMOST::Partitioner::Initialize	(	int *	argc,
		char ***	argv
	)

static

Initialize the use of partitioner.

Parameters

argc	The number of arguments transmitted to the function main.
argv	The pointer to arguments transmitted to the function main. The shortest call to this function with the default solver parameters is the following: Initialize(NULL,NULL);
