Abstract

A serialization construct is implemented within an environment of a number of parallel data flow graphs. A quiesce node is appended to every active data flow graph. The quiesce node prevents a token from passing to a next data flow graph within a chain before an execution of the active data flow graph has been finished. A serial data flow graph is implemented to provided for a serial execution while no other data flow graph is active. A serialize node is appended to a starting point of a serial data flow graph. A serialize end node is appended to an endpoint of the serial data flow graph. The serialize node is activated to start a serial operation. The serialize end node is activated after the serial operation has been terminated.
