Several people downvoted all my comments in bulk, including the one below that's a purely technical explanation of using multi CPU/GPU caffee. I personally do not care about points (moreover the same comment in another thread more than offset the 'karmic punishment' in this one) but since you're here, please have a look at the way some people are treating the downvote button.

I will keep things up a level and more broadly constructive in the future.
