[Trilinos-Users] [Kokkos-Developers] Multidimensional array

[Mark Hoemmen]

Greetings Einar -- It would be great to know a little bit more about what you are doing with tensors of order > 2.  If 2-D tensors (rather, dense matrices) suffice, there are a number of libraries you could use, but they would not necessarily help as much as Tpetra does with things like encapsulating data layout and distributing data.
