| KOKKOS_INLINE_FUNCTION void | runSpecialized3 (const TeamMember &teamMember) const |
| runSpecialized implementations are hand-coded variants of run() for a particular number of components. To allow comparisons with the generic implementation (both in terms of performance and for verification), we use the member variable forceNonSpecialized_ to determine whether runSpecialized is selected when a specialized implementation is available. | |

| KOKKOS_INLINE_FUNCTION void | operator() (const TeamMember &teamMember) const |
| long | approximateFlopCountPerCell () const |
| returns an estimate of the number of floating point operations per cell (counting sums, subtractions, divisions, and multiplies, each of which counts as one operation). | |
| int | teamSize (const int &maxTeamSizeFromKokkos) const |
| returns the team size that should be provided to the policy constructor, based on the Kokkos maximum and the amount of thread parallelism we have available. | |
| size_t | team_shmem_size (int team_size) const |
| Provide the shared memory capacity. | |
