Any modern compiler will see that this code does nothing and simply remove it. Your benchmark is a no-op :-)

Trust me, to build a computer for the top of the top500, you have to be pretty good at these. Well, at least space and power. With over 100,000 cores, without an efficient (dense) packaging you'll need a room way too big. And a dense packaging leads to all kind of heat issues, so you have to be power-efficient.

It would hurt both the GPU and the CPU performance. Maybe not in the same way, but still.

Plus the article complaining about the use of GPUs is stupid. GPUs can be and are used to solve real scientific problems. They are not as easy to efficiently use as the CPUs, but they are almost as versatile.

Even with an hypothetical hyper-fast network, 100.000 android phones won't get you anywhere near the top of the list.

Heck, even 100 000 Nehalem (core i7) cores won't get you in the top 5.

So, android phones ? You'll need millions of them.

Well, the diesels winning in Le Mans are not slow, but they are certainly very noisy and insanely expensive to buy and repair.

Well, mine is absolutely completely dead, and has been sitting in a drawer for years. But my laptop runs fine without it. I just have to use suspend-to-disk when going from one AC outlet to another.

No, you cannot.

Do you know that the laser used to measure the distance between the earth and the moon has a radius of over 6km when it reaches the moon, and that only one photon every few seconds comes back to the detector on earth ?

Considering how far the spaceship will be from earth, it is not even remotely possible to focus a beam precisely enough to transfer energy.

They must have the CIP module !

My bet is that this is a typo.
1.6 PB seems more reasonable.
