Particle Container Management (MC)

The following kernels manage the particle container, including initialization, repartitioning, merging, and defragmentation.

Type	Name	Policy	Brief Description	Number of Calls
reduction	mc_init_first	range(size)	Spawns particles by setting positions, calling model initialization, and calculating total mass.	1
for	get_repartition	range(size)	Counts the number of particles per compartment (if multiple compartments exist).	n_export
for	insert_merge	TeamPolicy(n_add_item, Kokkos::AUTO, Model::n_var)	Back-inserts to merge the main container and buffer.	n_step
scan	find_and_fill_gap	range(size)	Finds non-idle particles and replaces them with new ones (defragmentation).	If n_non_idle > threshold

Iteration Cycle Kernels

Each iteration cycle launches the following kernels:

Type	Name	Policy	Brief Description	Number of Calls
for	cycle_move	team: (static_cast<int>(range) + team_size - 1)/team_size, team_size	Moves particles based on the flowmap (if n_compartment > 1).	n_step
reduce	cycle_move_leave	team: (256, auto)	Returns the number of particles leaving (if continuous reactor with feed != 0).	n_step
reduce	cycle_model	team: (static_cast<int>(range) + team_size - 1)/team_size, team_size	Updates the model, handles division, and returns the number of particles leaving and waiting for allocation.	n_step
reduce	cycle_scatter	team: range(size)	Scatters particle contributions.	n_step

The following kernel is used for exporting data:

Type	Name	Policy	Brief Description	Number of Calls
for	get_properties	range(size)	Deep copies the particle container to the host in a view format for HDF5 export. Skips non-idle particles.	n_export
