China’s investment in supercomputers
China has long been a major player in the world of supercomputers, and its investment in this area of technology has been instrumental in its development of some of the most powerful machines in operation today.
While the united states is still home to the most powerful supercomputer in the world (as of 2019), China boasts the most machines in the Top 500 list, with 213 compared to America’s 205. This is a significant increase from 2018, when China had 160 supercomputers on the list compared to America’s 149.
China’s investment in supercomputing is part of its wider strategy to become a world leader in technology and AI. The country has poured billions of dollars into research and development in recent years, and its progress in this area has been rapid.
Supercomputers are used for a variety of tasks including weather forecasting, scientific research, and military applications. They are able to perform calculations at incredibly fast speeds, and their increasing power is helping researchers to tackle problems that were previously considered too difficult or complex.

The Sunway TaihuLight
Sunway TaihuLight is a supercomputer developed by China. It is notable for being the world’s most powerful supercomputer, as well as the first system to surpass 100 petaflops. It was developed by the National Supercomputing Center in Wuxi, China, and was released in June 2016.
The system is composed of 40,960 Shenwei SW26010 processors, which are based on the processing units used in Sunway’s Tianhe-2 supercomputer. Each of these chips contains 260 cores and has a peak performance of 1.45 teraflops. The system also includes 10 PB of disk storage and 12 PB of flash storage.
Sunway TaihuLight is three times more powerful than Tianhe-2, which was previously the world’s most powerful supercomputer. It is also twice as energy efficient, consuming just 15 megawatts of power.
The United States’ Supercomputers
In June 2015, the U.S. Department of Energy’s Lawrence Livermore National Laboratory in California completed Aurora, the country’s most powerful supercomputer. As of November 2017, Aurora is ranked as the fifth most powerful supercomputer in the world.
The United States’ investment in supercomputers
Although the United States has long been a world leader in supercomputing, it now lags behind China in both the number of operational systems and the speed of its most powerful computers. In November 2015, China’s Sunway TaihuLight became the world’s fastest supercomputer, with a top speed of 93.01 petaflops (quadrillions of calculations per second). The United States’ most powerful system, Titan, can perform 17.59 petaflops.
The United States has been working to regain its position as the world leader in supercomputing. In 2012, the Department of Energy (DOE) launched the CORAL project, which stands for Collaboration of Oak Ridge, Argonne and Lawrence Livermore National Laboratories. The project focuses on developing exascale computing systems, which are capable of performing one exaFLOPS (one quintillion or a billion billion calculations per second). To put this in perspective, an exaflops system could perform about one thousand trillion trillion operations per second.
The United States is not alone in its investment in exascale computing. China is also working on developing an exascale system and is expected to have one operational by 2020. Japan and European Union countries are also investing in this area of research and development.
The Titan, a supercomputer located at the Department of Energy’s Oak Ridge National Laboratory in Tennessee, is currently the fastest supercomputer in the United States. It is capable of performing 20,000 trillion operations per second, or 20 petaflops.
The Titan is a Cray XK7 system that uses a combination of CPUs and GPUs to achieve its high level of performance. The system has 18,688 nodes, each of which contains an AMD Opteron 6274 16-core processor and an NVIDIA Tesla K20X GPU accelerator. In total, the Titan has 710,144 processing cores and 363 TB of memory.
The system was built at a cost of $134 million and went into operation in October 2012.
The European Union’s Supercomputers
China has always been a head-to-head competitor with the United States in the technological field, but in recent years China has taken the lead in supercomputing. In October of 2016, China’s Sunway TaihuLight became the world’s most powerful supercomputer, surpassing the previous record holder, the Tianhe-2 (also located in China). With a top speed of 93 petaflops, the Sunway TaihuLight is nearly three times as fast as the Tianhe-2, and can perform around 125 quadrillion calculations per second. While the United States still has the most powerful supercomputer in the world (Summit, with a peak performance of 143.5 petaflops), China now has the most powerful supercomputer in the top 500 list.
The European Union’s investment in supercomputers
The European Union has been an important player in the development of supercomputers, often working in collaboration with China. The EU has invested heavily in supercomputing, and as a result, its supercomputers are among the most powerful in the world. However, China’s investment in supercomputing is growing at a much faster rate than the EU’s, and as a result, China is quickly catching up to the EU in terms of supercomputing power.
The EU’s investment in supercomputing has been driven by a desire to remain competitive in the global economy. Supercomputers are used for a variety of tasks, includingweather forecasting, climate modeling, financial analysis, and scientific research. They are also used for military applications, such as missile defense and Intelligence Surveillance Reconnaissance (ISR). The EU’s investment in supercomputing has been motivated by a desire to maintain a leadership role in these important fields.
China’s investment in supercomputing is motivated by similar considerations. China also wishes to remain competitive in the global economy and views supercomputing as vital to this goal. In addition, China seessupercomputing as critical to its military aspirations. In particular, China is interested in using supercomputers for nuclear weapons research and development.
The EU’s investment in supercomputing has helped it maintain a leadership position in the field. However, China’s much faster rate of investment means that it is quickly catching up to the EUin terms of supercomputing power. This trend is likely to continue, and eventually overtake, the EU’s current lead role in supercomputing
The Piz Daint
At the top of the TOP500 list is the Piz Daint, a CRAY XC50 system installed at the Swiss National Supercomputing Centre (CSCS) in Lugano. It achieved 19.6 petaflops on the LINPACK benchmark using NVIDIA Tesla P100 GPUs and Intel Xeon Phi processors.
Why China’s Supercomputer is the Best
China’s Supercomputer is the best because it can process more information than any other computer. It is also faster and more reliable.
The Sunway TaihuLight’s performance
The Sunway TaihuLight is the world’s fastest supercomputer, capable of performing 93 petaflops (quadrillion operations per second). It was developed by Chinese technology company Sunway Microelectronics.
The Sunway TaihuLight uses 10.65 million CPU cores and can sustain performance of 125 petaflops on the High Performance Linpack (HPL) benchmark. It outperforms the previous record holder, Tianhe-2, by almost three times.
The Sunway TaihuLight is also much more energy efficient than any other supercomputer. It runs on only 3.57 megawatts of power, which is about one-sixth of the power consumption of Tianhe-2.
The Chinese government has invested heavily in supercomputing research and development, and the Sunway TaihuLight is a product of that investment. The Chinese Academy of Sciences (CAS) has said that the supercomputer will be used for “advanced manufacturing, weather forecasting, climate change research, life science and many other fields.”
The Titan’s performance
China’s Sunway TaihuLight is the world’s fastest supercomputer. Tianhe-2, or the “Milky Way 2,” was the previous record holder for three years in a row, but TaihuLight knocks it out of the water with a performance of 93.01 petaflops per second. Tianhe-2 comes in at a very distant second with 33.86 petaflops per second.
One petaflop is equal to one quadrillion floating-point operations per second. In other words, TaihuLight can perform 93,010,000,000,000,000 calculations per second. For perspective, the most powerful computer available to the general public (MacBook Pro) can perform around 12 gigaflops, or 12 billion calculations per second.
So what gives TaihuLight its speed? For one thing, it uses 10 million CPU cores as opposed to Tianhe-2’s 3 million CPU cores. But more importantly, TaihuLight uses Chinese-developed 260-coreSW26010 processors instead of American Intel Xeon E5 CPUs. The Chinese processors are based on the older SPARC architecture while the Intel CPUs use a newer x86 architecture.
The Piz Daint’s performance
The Piz Daint is a Cray XC50 system located at the Swiss National Supercomputing Centre (CSCS) in Lugano, Switzerland. It is powered by NVIDIA Tesla P100 GPUs and Intel Xeon CPUs.
As of June 2018, the Piz Daint is the fastest supercomputer in the world for peak double-precision floating-point performance (Linpack), with a measured speed of 25.3 petaflops. It is also the fastest system for peak single-precision floating-point performance (GPU-only), with a measured speed of 122.3 petaflops. In terms of the High Performance Linpack benchmark, the Piz Daint is currently ranked as the fourth fastest supercomputer in the world, with a speed of 21.2 petaflops.
