Member Function Documentation

◆ compute()

void Arcane::MpiVariableSynchronizer::compute ( )

inlineoverridevirtual

Recalculates the synchronization information.

This operation is collective.

This function must be called if the entities in itemGroup() change owner or if the group itself evolves. TODO: call this function automatically if needed.

Implements Arcane::IVariableSynchronizer.

Definition at line 241 of file MpiParallelMng.cc.
