China aims to become supercomputer superpower

The US owned Jaguar has a top speed of 1.75 petaflops

China is ramping up efforts to become the world's supercomputing superpower.

Its Nebulae machine at the National Super Computer Center in Shenzhen, was ranked second on the biannual Top 500 supercomputer list.

For the first time, two Chinese supercomputers appear in the list of the top 10 fastest machines.

However, the US still dominates the list with more than half the Top 500, including the world's fastest, known as Jaguar.

The Cray computer, which is owned by the Oak Ridge National Laboratory in Tennessee, has a top speed of 1.75 petaflops.

One petaflop is the equivalent of 1,000 trillion calculations per second.

It is used by scientists conducting research in astrophysics, climate science and nuclear energy.

There is a need here to emphasize that at least 2 key applications of petaflop supercomputers for China's onong projectst that I can think of :


JXX and Aircraft Carriers:


1. Wind tunnel design and trial calculations

China has the largest wind tunnel in Asia, foe sure. It's officially 3rd largest in the world after the US and Russia. Unofficically, I've read somwhere that China's wind tunnel is fastly surpassing Russia's, becoming the 2rd largest in the world.

Using petaflop supercomputer to design and calculate results of trials is the key for both aerodynamics design of JXX ( J-10 has also been trialed here according to reports) and multiple detail design tasks of Aircraft Carriers.

There are not more than 9 companies/institutions from only 5 countries (USA, Russia, UK, France and China) in the entire world that possess such capabilities.


2. Petaflop supercomputer is the key for huge design task of aircraft carrier. e.g. It took Nimiz Class 1.5 years to produce more than 100,000 detailed designs; while without it, it took Russia more than double the time to accomplish designs for a mid-weight and much less complicated AC.


Therefore, this world's 2rd fastest supercomputer project must have been largely supported and pushed by China's Defence Industry for above urgent purposes IMO.
