Detailed Description

template<class LocalOrdinal, class GlobalOrdinal, class Node>
class MueLu::IndexManager_kokkos< LocalOrdinal, GlobalOrdinal, Node >

Container class for mesh layout and indices calculation.

Structure holding mesh parameters for structured mesh. Based on these parameters the IndexManager_kokkos computes indices in different index spaces and it also provides utilites for coarsening.
