object --+ | ParValue --+ | ParAccumulator
Global accumulator
ParAccumulator objects are used to perform iterative reduction operations in loops. The initial local value is zero (i.e. the passed-in zero object, not the number 0), which is modified by subsequent calls to the method addValue.

__init__(self, operator, zero) | |||
addValue(self,
value) Replace the internal value of the accumulator by internal_value = operator(internal_value, value). |
|||
ParValue |
calculateTotal(self) Returns a reduction over the local values on all processors |
