GPU inclusive time = 314.823 ms
CPU time = 66.9215 ms

Shameful that the GPU is taking longer than the CPU.

Re: Timing Results Assignment 7: Reduction Operation

incl = 102.700478 milliseconds
CPU calculations took 200.000000 milliseconds to run.
CPU: -82210.000000
GPU: -82206.462018

What is the prize for the winner of the contest??!! ;-)

Guys - I included everything I know in my algorithm - but it was impossible for me to get below 100 ms. Results on the level of 70 ms are impressive!! Is it due to some sophisticated algorithm, or because of the hardware you run your code on?
