During the maintenance period on Monday, 14 Oct 2024, all new projects will no longer create a container registry as part of the project area. Already existing projects will be unaffected at this time. Instead, users should utilize the official ORNL container registries at camden.ornl.gov (internal/moderate) and savannah.ornl.gov (external/low). Please see ORNL Today article for more info.

The data passed to MPI_Isend needs to remain available until after MPI_Wait, so use a class member variable instead.
This also means the member variable can't be const, so the workaround for some MPI_Isend implementations isn't needed anymore.
