Tpetra: Make BlockMultiVector implement the "new" DistObject interface
Created by: mhoemmen
@trilinos/tpetra
Current Behavior
Tpetra::BlockMultiVector currently implements the "old" DistObject interface (copyAndPermute, packAndPrepare, unpackAndCombine) instead of the "new" DistObject interface (copyAndPermuteNew, packAndPrepareNew, unpackAndCombineNew).
Motivation and Context
This blocks deprecation and removal of the "old" DistObject interface.
Definition of Done
- Implement copyAndPermuteNew, packAndPrepareNew, and unpackAndCombineNew
- Implement useNewInterface and have it return true
- Make sure all the tests pass
Possible Solution
The "new" DistObject interface permits a host-only implementation, which is what BlockMultiVector currently has. This should be a mechanical change.
