China Dominates the World TOP500 Supercomputers

you can quote them and tell them it is the time to deliver their promise.

This is the biggest fun from PDF.

You can't take them seriously. It's a people that is so incompetent, yet so confident, for some mysterious reasons. Sometimes, you would wonder if some political terms such as "freedom and democracy" actually make people insane.
 
What CPUs are used in Chinese supercomputers?


Both systems use native CPU and accelerator architectures

From the article below:
It seems that China already has two exascale supercomputers at once – no one else has such systems, not even the United States.


One is:

"The successor to TaihuLight, codenamed Oceanlite, is based on a new generation of Sunway chips (ShenWei) and has a minimum of 42 million cores and a peak performance of 1.3 Eflops in HPL. "

The other one:

Phytium, developed by Tianjin Phytium Technology.

" Phytium is responsible for their development, whose growth at one time was helped by the ban on the supply of Intel Xeon for Chinese supercomputers. The company has its own 7-nm Arm processors FeiTeng and Matrix Series DSPs. "

Coronavirus drug screening efficiency increased by 200 times China's new generation of Tianhe supercomputers shortlisted for the Gordon Bell Prize

On the evening of November 5, CCTV reported that the work of "Virtual Screening of Large-Scale Coronavirus Drugs Based on Free Energy Perturbation-Absolute Binding Free Energy Method" completed on the Tianhe New Generation Supercomputer was successfully shortlisted for the Gordon Bell coronavirus Special Award in 2021, which is the first time that China is shortlisted for this special award.

The work was nominated by Academician Kaixian Chen from the Shanghai Institute of Pharmaceutical Sciences of the Chinese Academy of Sciences, Professor Depei Qian from Beijing University of Aeronautics and Astronautics, and Professor Hans Westerhoff from the University of Amsterdam, the Netherlands.

The rapid screening and discovery of coronavirus emergency drugs (effective in reducing lethality and severe disease rates) was achieved by using the ultra-large scale computing power of the Tianhe next-generation supercomputer and using an internationally leading computational method for combined drug-target precision evaluation.

The team used important targets such as M-Pro and TMPRSS2 of coronavirus as research targets, and computationally evaluated nearly 1.8 million small molecule-target complexes from FDA-approved and mature commercial libraries, and completed more than 500,000 complex molecular dynamics simulation tasks within one week, and screened 98 compounds, among which 50 compounds showed high activity in biological activity tests with a hit rate of 51%, which is the highest level in the world today.

The results of the clinical trials of more than 100 cases of the computationally screened dipyridamole drug have been completed, which showed that after three weeks of dipyridamole intervention, the clinical symptoms of the coronavirus patients improved significantly, reaching a discharge rate of 87.5%, significantly better than the 40% discharge rate of the control group, with no cases of death and no cases of deterioration to critical, and that the drug improved the cure rate and reduced the death rate of the diseased.

After the drug was combined with Abirater, the discharge rate of patients with the coronavirus common type was 100%, and the average discharge time was 7 days, which was 4 days earlier than Abirater alone, showing good treatment effect.

According to the actual measurement, the efficacy of drug screening based on the free-energy perturbation-absolute binding free-energy method was improved by 200 times with the support of the Tianhe next-generation supercomputer.

The results are of great practical importance for achieving rapid drug response to unexpected outbreaks.

Meanwhile, based on the Tianhe new generation supercomputing platform, the Tianjin Supercomputing Center has also joined hands with the team of academician Zhang Boli of Tianjin University of Traditional Chinese Medicine to carry out the screening of active ingredients of traditional Chinese medicine for the treatment of coronavirus and to conduct research on the modernization of traditional Chinese medicine.

The Gordon Bell Award is the highest international academic award in the field of high-performance computing, known as the "Nobel Prize in supercomputing", selected and awarded by the ACM every year, with a large international influence.

The ACM Gordon Bell Special Prize for HPC-Based COVID-19 Research was established for the first time in 2020 due to the outbreak of the coronavirus epidemic to recognize outstanding research results in "supercomputing against the epidemic". The main criteria for evaluation are

The main criterion for the award is that the application of high performance computing and innovation has made a significant contribution to understanding the nature of disease, controlling the spread of disease, or discovering effective treatments.

In 2020, there were six finalists for this award, all of which were from the United States.

The Nobel of HPC, 2021 Gordon Prize is out.

2021 ACM Gordon Bell Prize Awarded to Team for Achieving Real-Time Simulation of Random Quantum Circuit

ACM, the Association for Computing Machinery, named a 14-member team, drawn from Chinese institutions, recipients of the 2021 ACM Gordon Bell Prize for their project, Closing the "Quantum Supremacy" Gap: Achieving Real-Time Simulation of a Random Quantum Circuit Using a New Sunway Supercomputer.

The members of the winning team are: Yong (Alexander) Liu, Xin (Lucy) Liu, Fang (Nancy) Li, Yuling Yang, Jiawei Song, Pengpeng Zhao, Zhen Wang, Dajia Peng, and Huarong Chen of Zhejiang Lab, Hangzhou and the National Supercomputing Center in Wuxi; Haohuan Fu and Dexun Chen of Tsinghua University, Beijing, and the National Supercomputing Center in Wuxi; Wenzhao Wu of the National Supercomputing Center in Wuxi; and Heliang Huang and Chu Guo of the Shanghai Research Center for Quantum Sciences.

Quantum supremacy is a term used to denote the point at which a quantum device can solve a problem that no classical computer can solve in a reasonable amount of time. Teams at Google and the University of Science and Technology of China in Hefei both claim to have developed devices that have achieved quantum supremacy.

According to the Gordon Bell Prize recipients, determining whether a device has achieved quantum supremacy for a given task (in a specific scenario) begins with sampling the interactions of the different quantum bits (qubits) in a random quantum circuit (RQC). As the number of possible interactions among qubits in a random quantum circuit is staggeringly large, simulating their interactions is a problem well-suited for a high-performance computer. However, the quantum physics behind the entangled qubits requires that the classical binary bits used in a supercomputer store and compute the information with exponentially-increasing complexity.

In their Gordon Bell Prize-winning work, the Chinese researchers introduced a systematic design process that covers the algorithm, parallelization, and architecture required for the simulation. Using a new Sunway Supercomputer, the Chinese team effectively simulated a 10x10x (1+40+1) random quantum circuit (a new milestone for classical simulation of RQC). Their simulation achieved a performance of 1.2 Eflops (one quintillion floating-point operations per second) single-precision, or 4.4 Eflops mixed-precision, using over 41.9 million Sunway cores (processors).

The project far outpaced state-of-the-art approaches to simulating an RQC. For example, the most recent effort, using the Summit supercomputer to simulate a random quantum circuit of the Google Sycamore quantum processor (which has 53 qubits), was estimated to take 10,000 years to perform. By contrast, the Chinese team’s approach employing the Sunway supercomputer takes only 304 seconds for a simulation of similar quantum complexity.

The Chinese team explained that they undertook this challenge because achieving real-time simulation of an RQC using a supercomputer would aid both in the development of quantum devices and in bringing algorithmic and architectural innovations within the traditional supercomputing community.

The ACM Gordon Bell Prize tracks the progress of parallel computing and rewards innovation in applying high performance computing to challenges in science, engineering, and large-scale data analytics. The award was presented today by former ACM President Cherri M. Pancake and Professor Mark Parsons, Chair of the 2021 Gordon Bell Prize Award Committee, during the International Conference for High Performance Computing, Networking, Storage and Analysis (SC21), which was held in St. Louis, Missouri, and virtually for those who could not attend.
 

Beside the grand prize above, two other notable Chinese achievement,
ACM Gordon Bell Prize nominees
While the quantum simulation research is taking home the prize, the other five nominees represent some of the most intensive research for some of the most pressing research applications in the world. Brief descriptions are included below; follow the links to their respective papers to learn more about each of the teams’ remarkable work.

Symplectic Structure-Preserving Particle-in-Cell Whole-Volume Simulation of Tokamak Plasmas to 111.3 Trillion Particles and 25.7 Billion Grids
If you don’t yet know what a tokamak is, just know that they might save the world: tokamaks use magnetism to trap plasma for the production of fusion energy. However, tokamaks are notoriously delicate and unstable, hence the current infeasibility of productive fusion energy. The HPC sector is working to change that: these dozen researchers from China, also using the new Sunway system, simulated the whole-volume confinement toroidal plasmas of a tokamak. These simulations reached up to 111.3 trillion particles and 25.7 billion grids, achieving sustained performance in excess of 201 petaflops double-precision, with the fastest iteration step hitting 298.2.

Extreme-Scale Ab Initio Quantum Raman Spectra Simulations on the Leadership HPC System in China
This research, also leveraging the new Sunway exascale system, pushed Raman spectroscopy – a kind of structural fingerprinting – to new limits. “Raman spectroscopy,” these dozen researchers from China explain, “provides chemical and compositional information that can serve as a structural fingerprint for various materials. Therefore, simulations of Raman spectra, including both quantum perturbation analyses and ground-state calculations, are of significant interest.” Full quantum mechanical simulations of Raman spectra for biological materials have proved particularly difficult, and here, the researchers conduct “fast, accurate, massively parallel full ab initio simulations of the Raman spectra of realistic biological systems” up to 3,006 atoms, achieving up to 468.5 petaflops in double-precision and 813.7 petaflops in mixed-half-precision and indicating “the potential for new applications of the QM approach to biological systems.” To learn more, read the paper here.​

Also notable is China finalist for special Gordon Bell Prize for COVID-19 Research -
Description: As a theoretically rigorous and accurate method, FEP-ABFE (Free Energy Perturbation-Absolute Binding Free Energy) calculations showed great potential in drug discovery, but its practical application was difficult due to high computational cost. To rapidly discover antiviral drugs targeting SARS-CoV-2 Mpro and TMPRSS2, we performed FEP-ABFE-based virtual screening for ∼12,000 protein-ligand binding systems on a new generation of Tianhe supercomputer. A task management tool was specifically developed for automating the whole process involving more than 0.5 million MD tasks. In further experimental validation, 50 out of 98 tested compounds showed significant inhibitory activity towards Mpro, and one representative inhibitor, dipyridamole, showed remarkable outcomes in subsequent clinical trials. This work not only demonstrates the potential of FEP-ABFE in drug discovery, but also provides an excellent starting point for further development of anti-SARS-CoV-2 drugs. Besides, ∼500 TB of data generated in this work will also accelerate the further development of FEP-related methods.​

Source: Xinhua| 2021-12-10 18:44:42|Editor: huaxia

BEIJING, Dec. 10 (Xinhua) -- China has issued a list of 10 application challenges for its new generation supercomputer, with an aim to build a quintillion-scale supercomputing application ecology, Science and Technology Daily reported on Friday.

The list includes the fusion simulation of a magnetic confinement fusion reactor, fluid mechanics simulation of a full-size aerospace vehicle, dynamic simulation of a digital cell atomic system, as well as refined numerical weather forecasting.

It also covers efficient and high-throughput virtual drug screening, a super-scale artificial intelligence pre-training model, and high-resolution sky survey image processing for Five-hundred-meter Aperture Spherical Radio Telescope (FAST) observation data.

The application challenges also include global seismic full waveform inversion, whole-brain neuron dynamic simulation, and sub-mesoscale global ocean numerical simulation in full resolution.

The 10 application challenges for the new generation supercomputer, which is capable of processing one quintillion calculations per second, were jointly issued by China's National Supercomputer Center in Tianjin and dozens of other research teams on Wednesday, according to the newspaper.

Scaling graph traversal to 281 trillion edges with 40 million cores | Proceedings of the 27th ACM SIGPLAN Symposium on Principles and Practice of Parallel Programming
1649254876140.png

ABSTRACT
Graph processing, especially high-performance graph traversal, plays a more and more important role in data analytics. The successor of Sunway TaihuLight, New Sunway, is equipped with nearly 10 PB memory and over 40 million cores, which brings the opportunity to process hundreds of trillions of edges graphs. However, the graph with an unprecedented scale also brings severe performance challenges, including load imbalance, poor locality, and irregular access of graph traversal workload.

To address the scalability problem, we propose a novel 3-level degree-aware 1.5D graph partitioning, which benefits from both delegated 1D and 2D partitioning. By delegating extremely heavy vertices globally and other heavy vertices on columns and rows in the processes mesh, we break the scalability wall of previous partitioning methods. Together with sub-iteration direction optimization, core group -aware core subgraph segmenting, and a new on-chip sorting mechanism using RMA, we achieve 180,792 GTEPS on a graph with 281 trillion edges, using 103,912 processors with over 40 million cores, achieving 1.75X performance and 8X capacity compared to the previous state of the art and conforming to the Graph 500 BFS benchmark[14].

BaGuaLu | Proceedings of the 27th ACM SIGPLAN Symposium on Principles and Practice of Parallel Programming
1649255863895.png
ABSTRACT
Large-scale pretrained AI models have shown state-of-the-art accuracy in a series of important applications. As the size of pretrained AI models grows dramatically each year in an effort to achieve higher accuracy, training such models requires massive computing and memory capabilities, which accelerates the convergence of AI and HPC. However, there are still gaps in deploying AI applications on HPC systems, which need application and system co-design based on specific hardware features.
To this end, this paper proposes BaGuaLu1, the first work targeting training brain scale models on an entire exascale supercomputer, the New Generation Sunway Supercomputer. By combining hardware-specific intra-node optimization and hybrid parallel strategies, BaGuaLu enables decent performance and scalability on unprecedentedly large models. The evaluation shows that BaGuaLu can train 14.5-trillion-parameter models with a performance of over 1 EFLOPS using mixed-precision and has the capability to train 174-trillion-parameter models, which rivals the number of synapses in a human brain.
 
Establishing a non-hydrostatic global atmospheric modeling system at 3-km horizontal resolution with aerosol feedbacks on the Sunway supercomputer of China - ScienceDirect
1649256315042.png

Abstract​

During the era of global warming and highly urbanized development, extreme and high impact weather as well as air pollution incidents influence everyday life and might even cause the incalculable loss of life and property. Although, with the vast development of atmospheric model, there still exists substantial numerical forecast biases objectively. To predict accurately extreme weather, severe air pollution, and abrupt climate change, the numerical atmospheric model requires not only to simulate meteorology and atmospheric compositions simultaneously involving many sophisticated physical and chemical processes but also at high spatiotemporal resolution. Global integrated atmospheric simulation at spatial resolutions of a few kilometers remains challenging due to its intensive computational and input/output (I/O) requirement. Through multi-dimension-parallelism structuring, aggressive and finer-grained optimizing, manual vectorizing, and parallelized I/O fragmenting, an integrated Atmospheric Model Across Scales (iAMAS) was established on the new Sunway supercomputer platform to significantly increase the computational efficiency and reduce the I/O cost. The global 3-km atmospheric simulation for meteorology with online integrated aerosol feedbacks with iAMAS was scaled to 39,000,000 processor cores and achieved the speed of 0.82 simulation day per hour (SDPH) with routine I/O, which enabled us to perform 5-day global weather forecast at 3-km horizontal resolution with online natural aerosol impacts. The results demonstrate the promising future that the increasing of spatial resolution to a few kilometers with online integrated aerosol feedbacks may significantly improve the global weather forecast.
