Distribute molecules and particles.

Parameters

atomic_kind_set	particle (atomic) kind information
particle_set	particle information
local_particles	distribution of particles created by this routine
molecule_kind_set	molecule kind information
molecule_set	molecule information
local_molecules	distribution of molecules created by this routine
force_env_section	...
prev_molecule_kind_set	previous molecule kind information, used with prev_local_molecules
prev_local_molecules	previous distribution of molecules, new one will be identical if all the prev_* arguments are present and associated

		type(section_vals_type), pointer	force_env_section
	)

Distributes the particle pairs creating a 2d distribution optimally suited for quickstep.

Parameters

cell	...
atomic_kind_set	...
particle_set	...
qs_kind_set	...
molecule_kind_set	...
molecule_set	...
distribution_2d	the distribution that will be created by this method
blacs_env	the parallel environment at the basis of the distribution
force_env_section	...

History

• local_rows & cols blocksize optimizations (Aug. 2003, MK)
• cleanup of distribution_2d (Sep. 2003, fawzi)
• update for molecules (Oct. 2003, MK)

Note

Intermediate generation of a 2d distribution of the molecules, but only the corresponding particle (atomic) distribution is currently used. The 2d distribution of the molecules is deleted, but may easily be recovered (MK).
