Detailed Description

Mesh repartitioning test class.

This class is used only to test mesh repartitioning. It simply changes the owner of the cells based on the numbering and without taking into account potential imbalances during computation time.

Member Function Documentation

◆ build()

void Arcane::MeshPartitionerTester::build ( void )

inlineoverridevirtual

Build-level construction of the service.

This method is called right after the constructor.

Reimplemented from Arcane::AbstractService.

Definition at line 67 of file MeshPartitionerTesterService.cc.

◆ cellsWeight()

ArrayView< float > Arcane::MeshPartitionerTester::cellsWeight ( ) const

inlineoverridevirtual

Implements Arcane::IMeshPartitioner.

Definition at line 89 of file MeshPartitionerTesterService.cc.

◆ computationTimes()

RealConstArrayView Arcane::MeshPartitionerTester::computationTimes ( ) const

inlineoverridevirtual

Implements Arcane::IMeshPartitioner.

Definition at line 83 of file MeshPartitionerTesterService.cc.

◆ imbalance()

Real Arcane::MeshPartitionerTester::imbalance ( ) const

inlineoverridevirtual

Computation time imbalance.

Implements Arcane::IMeshPartitioner.

Definition at line 85 of file MeshPartitionerTesterService.cc.

◆ loadBalanceMng()

ILoadBalanceMng * Arcane::MeshPartitionerTester::loadBalanceMng ( ) const

inlineoverridevirtual

Implements Arcane::IMeshPartitioner.

Definition at line 102 of file MeshPartitionerTesterService.cc.

◆ maxImbalance()

Real Arcane::MeshPartitionerTester::maxImbalance ( ) const

inlineoverridevirtual

Maximum allowed imbalance.

Implements Arcane::IMeshPartitioner.

Definition at line 87 of file MeshPartitionerTesterService.cc.

◆ maximumComputationTime()

Real Arcane::MeshPartitionerTester::maximumComputationTime ( ) const

inlineoverridevirtual

Implements Arcane::IMeshPartitioner.

Definition at line 81 of file MeshPartitionerTesterService.cc.

◆ mesh()

IMesh * Arcane::MeshPartitionerTester::mesh ( ) const

inlineoverridevirtual

Mesh associated with the partitioner.

Implements Arcane::IMeshPartitioner.

Definition at line 65 of file MeshPartitionerTesterService.cc.

Referenced by partitionMesh().

Here is the caller graph for this function:

◆ notifyEndPartition()

void Arcane::MeshPartitionerTester::notifyEndPartition ( )

inlineoverridevirtual

Notification when a re-partitioning finishes (after entity exchange).

Implements Arcane::IMeshPartitionerBase.

Definition at line 76 of file MeshPartitionerTesterService.cc.

◆ partitionMesh() [1/2]

void Arcane::MeshPartitionerTester::partitionMesh ( bool initial_partition )

overridevirtual

Re-partitions the mesh mesh

This method changes the owners of the entities and fills the IItemFamily::itemsNewOwner() variable of each entity family of the mesh mesh with the number of the new owning subdomain.

Note: This method is reserved for Arcane developers. If a module wishes to perform a re-partitioning, it must call the method IMeshUtilities::partitionAndExchangeMeshWithReplication() which handles both the partitioning and the exchange of information and supports domain replication.

Reimplemented from Arcane::IMeshPartitioner.

Definition at line 133 of file MeshPartitionerTesterService.cc.

◆ setCellsWeight()

void Arcane::MeshPartitionerTester::setCellsWeight	(	ArrayView< float >	weights,
		Integer	nb_weight )

inlineoverridevirtual

Allows defining the weights of objects to be partitioned: ILoadBalanceMng must now be used.

Implements Arcane::IMeshPartitioner.

Definition at line 91 of file MeshPartitionerTesterService.cc.

◆ setComputationTimes()

void Arcane::MeshPartitionerTester::setComputationTimes ( RealConstArrayView v )

inlineoverridevirtual

Computation time of this subdomain. The first element indicates the computation time of the subdomain corresponding to calculations whose cost is proportional to the cells. The following must be associated with a variable (to be done).

Implements Arcane::IMeshPartitioner.
