I could not disagree more with this statement. It assumes no other processes
ever need to use your hardware concurrently, which is usually _NOT_ the case.

Hi Carlo, that's a good point. I always prefer write code for multiple cores though, no matter the speed up. I hope as the technology evolves, the performance gains will become noticeable. And of course, another justification is that it can sometimes be achieved with tiny effort.

Following the discussion on #ifdefs, i discovered the _Pragma is named __pragma on MSVC (http://stackoverflow.com/questions/4782049/pragma-preprocessor-operator-in-visual-c) and it has a slightly different substitution pattern.

Best,
