A first graphical program executing on a first device may execute a first
graphical code portion for a plurality of iteration. Various systems and
methods for synchronizing the execution of the iterations of the first
graphical code portion with graphical code portions executing iteratively
in graphical programs on other devices are described. Various systems and
methods for synchronizing the execution of the iterations of the first
graphical code portion with operation of measurement devices or other
