Currently, the world's most powerful supercomputers can ramp up to more than a thousand trillion operations per second, or a petaflop. But computing power is not growing as fast as it has in the past. On Monday, the June 2015 listing of the Top 500 most powerful supercomputers in the world revealed the beginnings of a plateau in performance growth.
...
The development rate began tapering off around 2008. Between 2010 and 2013, aggregate increases ranged between 26 percent and 66 percent. And on this June's list, there was a mere 17 percent increase from last November.
...
Despite the slowdown, many computational scientists expect performance to reach exascale, or more than a billion billion operations per second, by 2020.
Hmm, if they reach exascale computing will the weatherman finally be able to predict if it's going to rain this afternoon? Because he sucks at that now.

It is a myth that supercomputers are built simply to top the LINPACK list. National prestige is a very small part of what they are used for.
The Chinese would have added nodes sooner [soylentnews.org] if it weren't for the recent and wrongheaded export ban to their supercomputing centers. Now they are going to add Chinese nodes instead. Heck, Intel should sue the feds over this.
Did we ban exports because we wanted to beat their record? Nope, we did it because Tianhe is used for simulating nuclear weapons and explosions... just as our Department of Energy supercomputers do.

The same story with India. The US banned export of HPC tech to India because India was (still is) chummier with Soviet Ruskitstan. Then India developed their own HPC tech instead of buying American stuff.

how is trying to slow the advancement of nuclear weaponry wrongheaded? do you think anyone should have more deadly nuclear weapons?

That's because you are dumb. Imagine yourself sitting next to North Korea (Pakistan, Israel, etc.)

It's not wrong headed, but it also is absolutely not what's intended, or happening. It's a hypocritical excuse, as NRL still operates, and an irrelevant excuse, as China is boosting its domestic manufacture.
I browse at -1 when I have mod points. It's unsettling.

It's not the intent that's wrongheaded, it's the measure. It is wrongheaded in the same way as it is wrongheaded to try to stop a flood by setting the area you want to protect on fire, on the theory that the fire will stop the water.

As someone who was previously involved with a large renderfarm [soylentnews.org], I confirm that it was upgraded to gigabit Ethernet switches solely to improve benchmarks. When a renderfarm node reads a .rib file and writes a .dpx file every 45 minutes or so, gigabit Ethernet makes minimal difference to performance.
