Function Documentation

assert_dir()

def palmmeteo.utils.assert_dir

(

filepath

)

Creates a directory for an output file if it doesn't exist already.

distribute()

def palmmeteo.utils.distribute	(		what,
			into,
			reverse = False
	)

Distributes integer into integers as evenly as possible

distribute_chunks()

def palmmeteo.utils.distribute_chunks	(		sizes,
			nthreads,
			prefix = (),
			reverse = False
	)

Distributes an n-dim array among threads as evenly as possible

ensure_dimension()

def palmmeteo.utils.ensure_dimension	(		f,
			dimname,
			dimsize
	)

Creates a dimension in a netCDF file or verifies its size if it already
exists.

find_free_fname()

def palmmeteo.utils.find_free_fname	(		fpath,
			overwrite = False
	)

getvar()

def palmmeteo.utils.getvar	(		f,
			varname,
		*	args,
		**	kwargs
	)

Creates a variable in a netCDF file or returns it if it already exists.
Does NOT verify its parameters.

tstep()

def palmmeteo.utils.tstep	(		td,
			step
	)

Fully divide datetime td by timedelta step.
