Cuda __syncthreads undefined. Without it-> random results

    Intellisense says it is undefined but your program should [compile and run fine with it](http://stackoverflow.com/questions/13893919/cuda-syncthreads-compiles-fine-but-is-underlined-with-red). If you do a google search on "cuda red underline" you'll get a variety of hits with suggestions on how to fix this issue. But you should be able to safely ignore the red underline in this case. – Robert Crovella Feb 24 '13 at 15:23
  • Intellisense is not a compiler. It says **undefined** for most of the device intrinsics. – sgarizvi Feb 24 '13 at 15:23
  • then what is the point of intellisense – MySchizoBuddy Jan 23 '14 at 21:01
