const

Handle to the currently executing team shared scratch memory.

KOKKOS_INLINE_FUNCTION int Kokkos::Impl::TeamPolicyInternal< ExecSpace, Properties >::member_type::league_rank

(

)

const

Rank of this team within the league of teams.

KOKKOS_INLINE_FUNCTION int Kokkos::Impl::TeamPolicyInternal< ExecSpace, Properties >::member_type::league_size

(

)

const

Number of teams in the league.

KOKKOS_INLINE_FUNCTION int Kokkos::Impl::TeamPolicyInternal< ExecSpace, Properties >::member_type::team_rank

(

)

const

Rank of this thread within this team.

KOKKOS_INLINE_FUNCTION int Kokkos::Impl::TeamPolicyInternal< ExecSpace, Properties >::member_type::team_size

(

)

const

Number of threads in this team.

KOKKOS_INLINE_FUNCTION void Kokkos::Impl::TeamPolicyInternal< ExecSpace, Properties >::member_type::team_barrier

template<class JoinOp >

KOKKOS_INLINE_FUNCTION JoinOp::value_type Kokkos::Impl::TeamPolicyInternal< ExecSpace, Properties >::member_type::team_reduce	(	const typename JoinOp::value_type	,
		const JoinOp &
	)		const

Intra-team reduction. Returns join of all values of the team members.

template<class ExecSpace, class... Properties>

template<typename Type >

KOKKOS_INLINE_FUNCTION Type Kokkos::Impl::TeamPolicyInternal< ExecSpace, Properties >::member_type::team_scan

(

const Type &

value

)

const

Intra-team exclusive prefix sum with team_rank() ordering.

The highest rank thread can compute the reduction total as reduction_total = dev.team_scan( value ) + value ;

template<class ExecSpace, class... Properties>

template<typename Type >

KOKKOS_INLINE_FUNCTION Type Kokkos::Impl::TeamPolicyInternal< ExecSpace, Properties >::member_type::team_scan	(	const Type &	value,
		Type *const	global_accum
	)		const

Intra-team exclusive prefix sum with team_rank() ordering with intra-team non-deterministic ordering accumulation.

The global inter-team accumulation value will, at the end of the league's parallel execution, be the scan's total. Parallel execution ordering of the league's teams is non-deterministic. As such the base value for each team's scan operation is similarly non-deterministic.
