I took only measure. One time. I haven't calculated the standard=20
deviation or error from measures.

I would say the results is just "equal".

And, I'm not sure how much hfp and sfp impacts the result of a task=20
executed mainly by hardware (gpu).


Do you think, by the results, that there is still any bug?
