Detailed Description

template<class LocalOrdinal, class GlobalOrdinal, class Node = Tpetra::KokkosClassic::DefaultNode::DefaultNodeType>
class Xpetra::ImportUtils< LocalOrdinal, GlobalOrdinal, Node >

Xpetra utility class for Import-related routines.

The routines should be independent from Epetra/Tpetra and be purely implemented in Xpetra.

template<class LocalOrdinal , class GlobalOrdinal , class Node = Tpetra::KokkosClassic::DefaultNode::DefaultNodeType>

void Xpetra::ImportUtils< LocalOrdinal, GlobalOrdinal, Node >::getPidGidPairs ( const Import< LocalOrdinal, GlobalOrdinal, Node > &  Importer, Teuchos::Array< std::pair< int, GlobalOrdinal > > &  gpids, bool  use_minus_one_for_local  )

inline

For each GID in the TargetMap, find who owns the GID in the SourceMap.

This only uses the Distributor and does not communicate. It returns (as an output argument) an array of (PID,GID) pairs. If use_minus_one_for_local is true, any GIDs owned by this processor get -1 instead of their PID.

void Xpetra::ImportUtils< LocalOrdinal, GlobalOrdinal, Node >::getPids ( const Import< LocalOrdinal, GlobalOrdinal, Node > &  Importer, Teuchos::Array< int > &  pids, bool  use_minus_one_for_local  )

Like getPidGidPairs, but just gets the PIDs, ordered by the column Map.
