Class that stores a strided map.
StridedMap extends the functionality of Xpetra::Map
It derives from Xpetra::Map and adds a std::vector, which contains the striding information. E.g. for a strided map with 3dofs per node (2 velocity dofs, 1 pressure dof) the striding information looks like: std::vector<size_t> stridingInformation; stridingInformation.push_back(2); // 2 velocity dofs stridingInformation.push_back(1); // 1 pressure dof
For this example the getFixedBlockSize() returns 3 (3 dofs per node). Providing a stridedBlockId parameter in the constructor the strided map only contains dofs of one strided block, e.g. with above stridingInformation the call
StridingMap M(33,0,stridiningInformation,comm,0); // striding block 0 (velocity dofs) returns a map with the gids 0, 1, 3, 4, 6, 7, ... (which contains only the velocity dofs)
and StridingMap M(33,0,stridiningInformation,comm,1); // striding block 1 (pressure dofs) creates a map with only the pressure dofs 2, 5, 8, ...

Map constructor with contiguous uniform distribution.
Map constructor with contiguous uniform distribution. The elements are distributed among nodes so that the subsets of global elements are non-overlapping and contiguous and as evenly distributed across the nodes as possible.
If numGlobalElements == Teuchos::OrdinalTraits<global_size_t>::invalid(), the number of global elements will be computed via a global communication. Otherwise, it must be equal to the sum of the local elements across all nodes. This will only be verified if Trilinos' Teuchos package was built with debug support (CMake Boolean option TEUCHOS_ENABLE_DEBUG=ON). If verification fails, a std::invalid_argument exception will be thrown.
