Function Documentation

dist_COM_index()

size_t dist_COM_index	(	int	i_mu,
		int	i_Ekin,
		int	i_Ptor,
		size_t	step_2,
		size_t	step_1 )

Internal function calculating the index in the histogram array.

Definition at line 17 of file dist_com.c.

dist_COM_init()

int dist_COM_init

(

dist_COM_data *

data

)

Initializes distribution data.

Parameters

data	pointer to data struct

Definition at line 29 of file dist_com.c.

dist_COM_free()

void dist_COM_free

(

dist_COM_data *

data

)

Free allocated resources.

Parameters

data	pointer to the data struct

Definition at line 46 of file dist_com.c.

dist_COM_offload()

void dist_COM_offload

(

dist_COM_data *

data

)

Offload data to the accelerator.

Parameters

data	pointer to the data struct

Definition at line 55 of file dist_com.c.

dist_COM_update_fo()

void dist_COM_update_fo	(	dist_COM_data *	dist,
		B_field_data *	Bdata,
		particle_simd_fo *	p_f,
		particle_simd_fo *	p_i )

Update the histogram from full-orbit markers.

Parameters

dist	pointer to distribution parameter struct
Bdata	pointer to magnetic field data
p_f	pointer to SIMD fo struct at the end of current time step
p_i	pointer to SIMD fo struct at the start of current time step

Definition at line 67 of file dist_com.c.

dist_COM_update_gc()

void dist_COM_update_gc	(	dist_COM_data *	dist,
		B_field_data *	Bdata,
		particle_simd_gc *	p_f,
		particle_simd_gc *	p_i )

Update the histogram from guiding center markers.

This function updates the histogram from the marker data. Bins are calculated as vector op and histogram is updates as an atomic operation to avoid race conditions.

Parameters

dist	pointer to distribution parameter struct
Bdata	pointer to magnetic field data
p_f	pointer to SIMD gc struct at the end of current time step
p_i	pointer to SIMD gc struct at the start of current time step
