i running matlab code on 4 core computer. using parfor command expected matlab using 4 cores run it. however, when go task manager see half of each core used - i.e. in total 50% of cpu taken matlab. is there reason why matlab not using full 100%? i not sure whether appropriate forum question. if not, please let me know. thanks, v the explanation have hyperthreading turned on. windows see things if there 8 cores rather 4. if turn hyperthreading off, bet you'll see rising 100%. matlab doesn't benefit hyperthreading in case (in fact there may small reduction in performance), if concern maximise matlab performance may turn off. of course, other applications (such outlook or word) benefit hyperthreading may suffer if that. there other possibilities - example, other cpu (such file i/o, memory) may bottleneck in application - if you're seeing consistent 50% usage, bet hyperthreading reason.

i wondering if should set objects before or after these methods in watchkit, , why? i think saw wwdc video saying should before super.willactivate(), can not remember 1 is. anyone can help? what should following: override func awakewithcontext(context: anyobject?) { // call super super.awakewithcontext(context) // whatever want self.dointerfaceconfiguration() } in method, should interface configuration. main reason behind doing configuration here in point can sure outlets connected objects , controller configured. more methods can found in apple docs . edit: answer second question willactivate() method, taken documentation: the willactivate method lets know when interface become visible on apple watch. use method make last minute updates controls or start times or other tasks. (do not use initialization.) use corresponding diddeactivate method perform final cleanup.
