@romintomasetti We've tasked @brian-kelley to look over Tpetra to see where else besides the CrsGraph rowptrs could benefit from the proposed LazyWrappedDualView.

@romintomasetti We've talked with them about WrappedDualView in the past, but they did not view that as something that should be integrated in Kokkos proper. I'll track down @crtrott and...

@romintomasetti I spoke with @crtrott and he suggested you write up the use case for a lazy dual view and present that to the Kokkos team.

For the one time MueLu_ParameterListInterpreterTpetra_MPI_4 timed out in the last month, we were getting this: ``` [ascic114][[11936,1],2][btl_tcp.c:559:mca_btl_tcp_recv_blocking] recv(17) failed: Connection reset by peer (104) [ascic114][[11936,1],1][btl_tcp.c:559:mca_btl_tcp_recv_blocking] recv(17) failed: Connection reset by...

Tempus just bit me again :) https://github.com/trilinos/Trilinos/pull/12393

@sebrowne Can we get Trilinos to try the magic OMPI_MCA_btl flags?

Lovely. We currently do not test CUDA 12 or GCC 12. Any suggestion as to where we can find a machine to reproduce this?

@maartenarnst I finally got around to trying a build on weaver (IBM Power) w/ GCC 12.2, Cuda 12.0 and OpenMPI 4.1.4 and Tpetra compiles just fine. Can you post whatever...

@maartenarnst Configure I used: ``` cmake \ -D CMAKE_CXX_COMPILER=`which mpicxx` \ -D CMAKE_C_COMPILER=`which mpicc` \ -D TPL_ENABLE_MPI=ON \ -D TPL_ENABLE_CUDA=ON \ -D Kokkos_ARCH_VOLTA70=ON \ -D BUILD_SHARED_LIBS=ON \ -D Trilinos_ENABLE_Epetra=OFF \...

@maartenarnst I have a PR up which blindly tries @bathmatt's fix. Can you check?
