Steen Schmidt Posted July 12, 2011 Report Share Posted July 12, 2011 I ran across this page which basically states that when setting a VI to background priority (lowest) it is deferred to running in normal priority: http://digital.ni.com/public.nsf/allkb/D6F5480F7F3E9CAD8625778F00652246 It states this as "known behaviour"? I must say I didn't know that, especially not since several other pages recommending priority level setup explains about background priority without mentioning this "fact". For instance; http://digital.ni.com/public.nsf/allkb/84081F249CEF7AB7862569450074168C http://zone.ni.com/reference/en-XX/help/370622E-01/lvrtconcepts/deterministic_apps_vi_priorities/ Does any of you know for a fact that setting a VI to background priority have the same effect as setting it to normal priority? On all targets including Real-Time? Cheers, Steen Quote Link to comment
spaghetti_developer Posted July 13, 2011 Report Share Posted July 13, 2011 Look at this: http://digital.ni.com/public.nsf/allkb/D6F5480F7F3E9CAD8625778F00652246 Hoping it answers your question! Quote Link to comment
Cat Posted July 14, 2011 Report Share Posted July 14, 2011 http://digital.ni.co...625778F00652246 I'm confused (not unusual). The above article states, "It is known behavior that this setting coerces the priority to normal priority. It is not possible to set a VI priority to anything lower than normal priority from within the VI Properties Window." So why does the option even exist?? I occassionally used background priority a long time ago when CPUs weren't quite so fast. Was it all just smoke and mirrors or is this a recent "feature"? Quote Link to comment
