C114 News Beijing time November 19th news (Yu] At the recent Hybrid Virtual / In-Person SC21 meeting, 14 people from the river laboratory, Tsinghua and Wuxi superior centers have won this year The highest awards in the field Gorden Bell Awards - Using the new hundred billionary Shuangwei system to simulate quantum circuits.

It is understood that the Gordon Bell Prize is established in 1987, which is the highest academic award in the field of international high-performance computing applications, known as the "Nobel Award" in the superior field, mainly issued to high performance applications. The most outstanding achievements in the field are selected and issued by ACMs and have a large international influence. The winners will receive a $ 10,000 bonus by HPC Pioneer Gordon Bell.

ACM is intended to "track the progress of parallel calculation, especially emphasis on innovation rewards in the field of scientific, engineering, and large-scale data analysis." This year's Gorden Bell Prince has six projects involving quantum computing, molecular motivation, spectroscopy and nuclear fusion.

Reduce "Quantum Hegemony" Ditch: Use a new Shuangwei Supercomputer to achieve random quantum circuit simulation

14 researchers from the Zhejiang Lab, Tsinghua University, Wuxi National Super Computing Center and Shanghai Quantum Science Research Center use large-scale new Shuangwei 100 billion system to pioneer the quantum.

"With the" Quantum Hegemony "declaration published by Google in 2019, the Sycamore superconductive quantum computer is more than 100 billion times higher than Summit, the strange dawn begins to start with a more active way," researchers wrote, "IBM research The team later responded that they can complete the simulation on the classic Summit Supercomputer ... is within a few days, not 10,000 years. "

The team uses the quantum sampling of random quantum circuits as an example problem that solves this preceptive quantum advantage. The random quantum simulator of the researchers combines the powerful function of the Sunway Exascale system, simulating a 10 & Times; 10 (quantum bit) & Times; (1 + 40 + 1) (depth) circuit, sustained performance achieves an amazing 12 billion billion Single exact calculation or 440 billion mixed precision calculations,Researchers say this is "new milestones of classic simulation of quantum circuit". They reduce the analog sampling time from previously estimated 10,000 years to 304 seconds.

* The above figure is provided by researchers, mainly classic random quantum circuit simulations summarizes. The X axis represents the number of quantum bits; the Y axis represents the required corresponding memory space; the size of the circle and the rectangle represents the complexity / depth of the circuit.

ACM Gordon Bell Award Nomination:

While the quantum simulation studies receive award, other five nominated representatives represent the most in-depth study of some of the most urgent research applications in the world.

Up to 67 researchers participated in this study, eventually developed a special Anton 3 molecular dynamics supercomputer designed and built by D. E. Shaw. The researchers report that Anton 3 can simulate a million atoms at 512 nodes at a speed of 100 microseconds per day, and each simulated 1 microsecond energy is less than any other machine. To achieve this, they have implemented a series of architectural and algorithm improvements, including a new custom network, specialized pair interaction with different precision, and a "Manhattan Method" for solving non-bound interactions. new method.

This study also used the new Shenwei Billion billion system to push the Raman spectrum-a structural fingerprint to a new limit. More than a dozen researchers from China explained that "Raman spectroscopy provides chemical and component information, which can be used as structural fingerprints of various materials. Therefore, the simulation of Raman spectroscopy, including quantum perturbation analysis and basic calculation It is of great significance. "The full-quantum mechanical simulation of the Raman spectrum of biological materials has been proven to be particularly difficult, here, the researchers have conducted" fast, accurate, large-scale parallel real biological system Raman Spectroscopy full-scale calculation simulation " Up to 3006 atoms, double precision reached 468.5 petaflops, mixed half precision reached 813.7 petaflops, which indicates the "QM method in biological system new application potential".

These researchers observed the BC8 phase of carbon "long-term search" at extreme pressure and extreme temperatures. To this end, they run on the US Leadership Summit system, command 4,650 nodes within 24, and show "SNAP [Molecular Dynamics] unprecedented extensibility and unparalleled real world performance". On behalf of the simulation of physical time nanoseconds, the simulation achieved more than 97% of parallel efficiency and the peak computing capacity of 50 Petaflops, which was used for 20 billion atomic molecular dynamics simulations on nearly 28,000 GPUs across SUMMIT. The researchers said that this record is 6.2 million atomic steps / nodes, which is 22.9 times the previous record.
