CUDA kernel - nested for loop

Question

Hello I\'m trying to write a CUDA kernel to perform the following piece of code.

for (n = 0; n < (total-1); n++)
{
  a = values[n];

  for ( i = n+1; i &         


        

Answer 1

I'll probably be way wrong but the n < (total-1) check in

for (int n = idx; n < (total-1); n += blockDim.x*gridDim.x)

seems different than the original version.
