Sigh! Already today, and even more tomorrow, this is often false for D too. In my computer I have a cheap GPU that is sleeping while my D code runs. Even my other core sleeps. And I am using one core at 32 bits only.
You will need ways to data-parallelize and other forms of parallel processing. So maybe nornmal loops will not cuti it. I think the best way to go is following the ideas of the Chapel language I have shown a bit here:
