Hi Jerur!
Generally speaking, there isn't an easy way to assign one VI to one processor and another VI to another processor. This is controlled by the OS and is independent of LabVIEW. However, if you are running windows, you may be able to make calls to the OS through the Microsoft SDK DLLs. Look at this thread for more info:
