Function Documentation

KOKKOS_INLINE_FUNCTION void AoSoA_2_simd	(	SimdParticles &	part_one,
		const VecParticles *	part,
		int	a_vec,
		int	s_vec
	)

Copy from the AoSoA to a local SoA of array length SIMD_SIZE. This should be obsolete at some point

Parameters

[out]	part_one	The local SimdParticle array
[in]	part	The particle AoSoA
[in]	a_vec	The index in the inner array of the AoSoA
[in]	s_vec	The index in the outer array of the AoSoA

KOKKOS_INLINE_FUNCTION void simd_2_AoSoA	(	VecParticles *	part,
		const SimdParticles &	part_one,
		int	a_vec,
		int	s_vec
	)

Copy from local SoA of array length SIMD_SIZE back into the AoSoA. This should be obsolete at some point

Parameters

[in,out]	part	The particle AoSoA
[in]	part_one	The local SimdParticle array
[in]	a_vec	The index in the inner array of the AoSoA
[in]	s_vec	The index in the outer array of the AoSoA

KOKKOS_INLINE_FUNCTION void update_dpht	(	SimdPhase &	dpht,
		const SimdPhase &	dph,
		const SimdPhase &	dphm
	)

Add the second vector of phase derivatives and 2x the third vector to the first, i.e. dpht = dpht + dph + 2 dphm (for use in RK4)

Parameters

[in,out]	dpht	Vector of phase derivatives
[in]	dph	Vector of phase derivatives
[in]	dphm	Vector of phase derivatives

		const SimdPhase &	dph
	)

Update a vector of particle phases with a time step

Parameters

[out]	ph_new	Vector of new phase
[in]	ph	Vector of old phase
[in]	local_dt	Time step size
[in]	dph	Vector of time derivatives of the phase
