"In the research, Google reportedly claimed that it takes their new quantum processor just around 200 seconds to make calculations that existing supercomputers would require around 10,000 years to perform. They also said the processor requires mere 30 seconds to complete a task the Google Cloud server would need 50 trillion hours to do"

This is all fake news. Latest and best super computer is done by China. I don't think google is able to surpass China's supercomputer so fast.

China? TOP500 number 1. and 2. are in USA.

Nope are not. China is leading ahead of USA in the technology race... Just ask Nobptw on fishtest... :) :) :D

no

Does quantum supremacy make quantum computers better than conventional computers?

No. Google's achievement only means its quantum computer could outperform a classical supercomputer on this one complex calculation.

The Google researchers say in their paper that their quantum computer may also have uses in optimization problems, machine learning as well as materials science and chemistry.

But it is unclear how much of an advantage or increase in speed Google's new quantum computing hardware, which it used to achieve quantum supremacy, will have in these other applications.

And Google's machine is not yet powerful enough to tackle other difficult mathematical problems, such as breaking current encryption systems, a task which involves factoring very large prime numbers, according to the research paper.

For many business applications, in fact, today's quantum computers are no match for the power and accuracy of today's conventional laptops.

For the fastest machines around, the top two are at Oak Ridge Lab and Lawrence Livermore Labs. The NEXT two are in China...

That is when you count flops, the top two use a bunch of NVidia GV100 racks, maybe nice for a NN engine. The new Chinese Tianhe-3 will be operational next year and is going to surpass the IBM Summit by a factor of 5 to 6.

Yea, Exascale is underway

https://en.wikipedia.org/wiki/Exascale_computing

The U.S. will join probably 2021 with Aurora (Intel) and Frontier (AMD).

I guess most of them will use some kind of heterogeneous computing, a CPU/GPU mix.

These are the machines we know about. I'm pretty sure the NSA won't tell us where the faster machines are, and what they're already able to do. :wink:

If true it looks like Moore's law is being surpassed when it comes to supercomputers.


"Exascale computing refers to computing systems capable of at least one exaFLOPS, or a billion billion (i.e. a quintillion) calculations per second. Such capacity represents a thousandfold increase over the first petascale computer that came into operation in 2008.[1] "

Supercomputer stagnation: New list of the world’s fastest computers casts shadow over exascale by 2020

By Sebastian Anthony on June 24, 2014 at 3:06 pm
..

Yesterday, Top 500 released the updated list of the world’s fastest supercomputers, and it revealed a rather worrying trend: Supercomputer performance gains are slowing down, rather than speeding up. When most of the world’s computing superpowers have announced their intentions to create exascale (1000 petaflops) supercomputers by 2020, this would appear to be a bit of a problem.

The Top 500 list is updated twice a year, in June and November. While the combined performance of all 500 supercomputers is still up from November 2013, the trend is a lot flatter than the long-term trend from the last four years or so. In the graph below, you can see how the latest data point (the blue dot) is almost fully below the trend line. You can also see that, also unusually for the last few years, one supercomputer has stuck to the number-one spot for the last 18 months (the Chinese Tianhe-2). And finally, the yellow dots — which plots the performance of the 500th-fastest supercomputer over the last 20 years — is also starting to dip below the long-term trend.
