Asymmetric global function

Constructor: ParRootFunction(|root_function|, |other_function|=None)

Arguments:

Global functions are called with global object arguments. The local values of these arguments are then passed to the local function, and the result is returned in a ParValue object.

A ParRootFunction differs from a ParFunction in that it uses a different local function for processor 0 than for the other processors. ParRootFunction objects are commonly used for I/O operations.

Method Details

init(self, local_function, other_function=None)
(Constructor)

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Parameters:

local_function (callable) - the local function for processor 0
other_function (callable) - the local function for all other processors. The default is a function that returns None.

Overrides: object.__init__
