Modules
module	io_server_state_writer_mod
	The IO server state module which will write out the current state of the IO server to a NetCDF file.

Functions/Subroutines
subroutine, public	io_server_state_writer_mod::set_serialise_write_field_manager_state (serialise_writer_field_manager_state_arg, prepare_to_serialise_writer_field_manager_state_arg, is_write_field_manager_up_to_date_arg)
	Sets the procedure to call for serialises the field manager state, this is handled in this manner due to the ordering dependencies between these modules. More...
logical function, public	io_server_state_writer_mod::is_io_server_state_writer_ready (timestep)
	Determines whether the IO server state writer is ready (i.e. state is at a specific level for the timestep) The timestep to check the IO server is up to date with. More...
subroutine	io_server_state_writer_mod::prepare_io_server_state_storage (io_configuration, writer_entries, time_points)
	Will determine the size of the package for different facets of the IO server state and kick off non-blocking collective calls to aggregate the sizes on each IO server process which is needed for the NetCDF dimension sizing and location in this. Note that during this certain locks are issued to ensure sizes don't change between this and physical packaging. More...
integer(kind=8) function	io_server_state_writer_mod::prepare_to_serialise_writer_entries_time_points (time_points)
	Prepares to serialise the writer entry time points. More...
subroutine	io_server_state_writer_mod::serialise_writer_entries_time_points (time_points, byte_data)
	Serialises the writer entry time points which are held in a hashmap. More...
subroutine, public	io_server_state_writer_mod::define_io_server_state_contributions (io_configuration, writer_entries, time_points, netcdf_file)
	Defines the dimensions and variables in a NetCDF file that consitute the IO server current state. This will call out to prepare all IO state for storage (determines the size of each byte code and issues locks for consistency.) More...
subroutine	io_server_state_writer_mod::define_state_storage (netcdf_file, entries_directory_dim_id, base_key, expected_global_entries)
	Defines some state storate for a specific facet of the IO server. This creates the directory (location for each IO server where to load their data), the dimension and the variable. Note this uses the ISO C bindings to NetCDF to support 64 bit dimension and field lengths. More...
subroutine, public	io_server_state_writer_mod::write_io_server_state (io_configuration, writer_entries, time_points, netcdf_file)
	Packags up and writes the actual IO server state into the NetCDF file. The act of serialisation will effectively unlock the IO server state locks that were issued in the preparation call (this is to ensure consistency between reported size and actual size when it comes time to package up.) More...
subroutine	io_server_state_writer_mod::write_state_storage (netcdf_file, writer_entry_start_point, my_io_rank, base_key, raw_byte_code)
	Writes out the state for a specific facet into the NetCDF file. Note that this uses the ISO C bindings into NetCDF to support 64 bit counts, starts and strides. More...
