    Reduction kernel slow and unstable?


      Reduction kernels runs very slow on my system.

      I simply tried the sample reduction code with default size (64x64) and got the result:

      Width   Height  Iterations      GPU Total Time 
      64      64      1               1.781000

      And I got segment fault when I try './reduction -i 2 -t'.

      I wonder if the segment-fault problem is also related to the second-iteration problem I just posted.
