Graph Key

Nodes of different colours represent the following:

Solid arrows point from a submodule to the (sub)module which it is descended from. Dashed arrows point from a module or program unit to modules which it uses.
Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

Subroutines

public subroutine find_steady_state(steady_state, generation_number, global_input_board, global_nrows, global_ncols, base_mpi_communicator, nprocs)

Subroutine to find the steady state of the game of life

Arguments

Type	Intent	Optional	Attributes		Name
logical,	intent(out)			::	steady_state	Logical flag indicating whether the global board has reached a steady state
integer,	intent(out)			::	generation_number	The number of generations required to reach the steady state
integer,	intent(in),		dimension(:,:), allocatable	::	global_input_board	The global board representing the current state of the game
integer,	intent(in)			::	global_nrows	The number of columns in the global board
integer,	intent(in)			::	global_ncols	The number of rows in the global board
integer,	intent(in)			::	base_mpi_communicator	The base MPI communicator for parallel processing

public subroutine evolve_board(current_board, new_board)

Evolve the board into the state of the next iteration

Arguments

Type	Intent	Optional	Attributes		Name
integer,	intent(in),		dimension(:,:), allocatable	::	current_board	The current state of the board
integer,	intent(inout),		dimension(:,:), allocatable	::	new_board	The new state of the board

public subroutine check_for_steady_state(steady_state, current_board, new_board)

Check if we have reached steady state, i.e. current and new board match

Arguments

Type	Intent	Optional	Attributes		Name
logical,	intent(out)			::	steady_state	Logical to indicate whether current and new board match
integer,	intent(in),		dimension(:,:)	::	current_board	The board as it currently is before this iteration
integer,	intent(in),		dimension(:,:)	::	new_board	The board into which the new state has been stored after this iteration
