Function Documentation

void copy_particles_from_device	(	Species< DeviceType > &	species,
		const TmpSpecies< DeviceType > &	tmp_species
	)

Copies particles to the host (Fortran particle AoSoA) from the device (Cabana AoSoA data structure) by getting the pointer to the Fortran particles and wrapping that in an unmanaged Cabana AoSoA.

Parameters

[in]	species	contains the CPU particles
[in,out]	tmp_species	is the object containing the particles on device

Returns

void

void copy_particles_to_device	(	TmpSpecies< DeviceType > &	tmp_species,
		const Species< DeviceType > &	species
	)

Copies particles from the host (Fortran particle AoSoA) to the device (Cabana AoSoA data structure) by getting the pointer to the Fortran particles and wrapping that in an unmanaged Cabana AoSoA.

Parameters

[in]	species	contains the CPU particles
[in,out]	tmp_species	is the object containing the particles on device

Returns

void

Here is the caller graph for this function:

void set_buffer_particles	(	const TmpSpecies< DeviceType > &	tmp_species,
		int	n_ptl
	)

Fills the remainder of the last AoSoA vector with realistic-looking particles (clones of the final particle). Since gid is set to -1, they will basically act as tracers in the kernel. Ideally garbage data in this buffer doesn't affect anything, but better to be safe here

Parameters

[in,out]

tmp_species

is the object containing the particles on device

Returns

void

Here is the caller graph for this function:

void set_buffer_phase0	(	const TmpSpecies< DeviceType > &	tmp_species,
		int	n_ptl

Fills the remainder of the last AoSoA phase0 vector with realistic-looking particles (clones of the final particle). Since gid is set to -1, they will basically act as tracers in the kernel. Ideally garbage data in this buffer doesn't affect anything, but better to be safe here
