Here is the call graph for this function:

◆ computeAndApplyConstraints()

void Arcane::mesh::MeshPartitionConstraintMng::computeAndApplyConstraints ( )

virtual

Computes and applies constraints.

It computes constraints on the mesh by applying the IMeshPartitionConstraint::addLinkedCell() method for each constraint and applies them by modifying the IItemFamily::itemsNewOwner() variable of the cells. All cells that must be linked in it are then placed in the same partition.

This operation does not guarantee that the resulting partitions are balanced in terms of load. For this, a re-partitioning service (IMeshPartitioner) must be used that takes these constraints into account.

This operation is collective.

Implements Arcane::IMeshPartitionConstraintMng.

Definition at line 124 of file MeshPartitionConstraintMng.cc.

◆ computeAndApplyWeakConstraints()

void Arcane::mesh::MeshPartitionConstraintMng::computeAndApplyWeakConstraints ( )

virtual

Computes and applies constraints.

It computes constraints on the mesh by applying the IMeshPartitionConstraint::addLinkedCell() method for each constraint and applies them by modifying the IItemFamily::itemsNewOwner() variable of the cells. All cells that must be linked in it are then placed in the same partition.

Implements Arcane::IMeshPartitionConstraintMng.

Definition at line 185 of file MeshPartitionConstraintMng.cc.

◆ computeConstraintList()

void Arcane::mesh::MeshPartitionConstraintMng::computeConstraintList ( Int64MultiArray2 & tied_uids )

virtual

Computes constraints and returns a list of linked entities.

It computes constraints like computeAndApplyConstraints() but does not modify the owner. Instead, it returns a list containing lists of the uniqueId() of the entities that must be linked.

This operation is collective.

Implements Arcane::IMeshPartitionConstraintMng.

Definition at line 135 of file MeshPartitionConstraintMng.cc.

◆ computeWeakConstraintList()

void Arcane::mesh::MeshPartitionConstraintMng::computeWeakConstraintList ( Int64MultiArray2 & tied_uids )

virtual

Computes constraints and returns a list of linked entities.

It computes constraints like computeAndApplyConstraints() but does not modify the owner. Instead, it returns a list containing lists of the uniqueId() of the entities that must be linked.
