Hello again,

Sorry, I don't understand why at line 67 the compiler complains about out-of-bounds, do you know which part causes out-of-bounds access?

Sorry, I had to manually define BLOCK_SIZE and II_CYCLES to test your code and forgot to adjust the line numbers accordingly. You should deduct 3 from the line numbers I posted above to match your code. The second warning is on line 64 on your code where "presult[e+1]" would be out of bounds for e=II_CYCLES.
