Preferred execution system

[Nitrof]

What is the exact meaning of:

User interface (I know)
Standard ?
Instrument IO ?
Data acquisition ?
Other 1 ???
Other 2 ???
Same as caller (I know)

I know that it also depend on if your computer is a Single or Dual Processor

Thanks!

I may be wrong, but I think the five available execution systems are basically identical (i.e. the Data acqusition system is not any more optimized for DAQ operations than the instrument IO system e.g.), NI has just assigned different names for them to make it easier to remember/automatically associate with the right/consistent parts of your code...Unless anything else is defined the VIs will run in the standard execution system. Keeping time-critical/consuming parts of your code away from the UI is always a good start...

Greg McKaskle has written several good answers about execution systems:
