Functions
__kernel void	seed_candidates (__global const unsigned int *iset, __global const int *imove, __global const unsigned int *ilevel, __global const unsigned int *level, __global const float *m0, __global int *miter, __global const vec *r, __global unsigned int *isplit, __global ivec *split_cell, __global float *split_dist, __constant float *dr_level0, unsigned int N)
	Look for all the seed candidates, i.e. all the particles which have a refinement level target lower than their current value.
__kernel void	seeds (__global const unsigned int *iset, __global const unsigned int *isplit_in, __global unsigned int *isplit, __global int *miter, __global const ivec *split_cell, __global const float *split_dist, __global const uint *icell, __global const uint *ihoc, unsigned int N, uivec4 n_cells)
	Get only one seed per cell.
__kernel void	set_isplit_in (__global const unsigned int *isplit, __global unsigned int *isplit_in, unsigned int N)
	Create a copy of isplit, where everything is 0 except the seeds, which take the value 1. Such array can be used to count the number of new particles to become generated.
__kernel void	children (__global const int *imove, __global const unsigned int *iset, __global const vec *r, __global const unsigned int *ilevel, __global unsigned int *isplit, __global int *miter, __global const uint *icell, __global const uint *ihoc, __constant float *dr_level0, unsigned int N, uivec4 n_cells)
	Look for all children, close enough to the seed.
__kernel void	weights (__global const unsigned int *iset, __global const unsigned int *ilevel, __global const vec *r, __global const unsigned int *isplit, __global float *split_weight, __global const uint *icell, __global const uint *ihoc, __constant float *dr_level0, unsigned int N, uivec4 n_cells)
	Compute the contribution weight of each children particle.
__kernel void	generate (__global int *imove, __global int *iset, __global const unsigned int *isplit, __global unsigned int *split_invperm, __global unsigned int *ilevel, __global unsigned int *level, __global int *miter, __global uint *mybuffer, unsigned int N, unsigned int nbuffer)
	Associate a buffer particle to a seed.
__kernel void	fields (__global const unsigned int *iset, __global const uint *isplit, __global const uint *mybuffer, __global const unsigned int *ilevel, __global const float *split_weight, __global float *m0, __global float *m, __global vec *r, __global vec *u, __global vec *dudt, __global float *rho, __global float *drhodt, __global const uint *icell, __global const uint *ihoc, __constant float *dr_level0, unsigned int N, uivec4 n_cells)
	Collect the children, and the seed itself, in order to compute the field values of the buffer partner particle.
