Computer researchers in China using domestically made graphics processors have achieved a near-tenfold boost in performance over powerful US supercomputers that rely on Nvidia’s cutting-edge hardware, according to a peer-reviewed study.

The accomplishment points to possible unintended consequences of Washington’s escalating tech sanctions while challenging the dominance of American-made chips, long considered vital for advanced scientific research.
The researchers said that innovative software optimisation techniques enabled them to improve efficiency gains in computers powered by Chinese-designed graphics processing units (GPUs) to outperform US supercomputers in certain scientific computations.

But maybe behind hardware all is nvidia gpu kek

unker oni hav 1 question: bila boleh beli????

GPU are gamers market. How many you know would use it for computational studies and AI development?

Banyak mimpi saja. Claim so much, no applicable real-life application also. Tabloid content.

nowadays ppl use NPU for this.. but okay, whatever makes them happy..

I do hope they can success, i want to see new competitors. The GPU scene is rather bad now with Nvidia dominating the high-end market. I want GPU to be as cheap as possible with fierce competitions...

Read carefully, is supercomputers and simulations. As long as you use enough chips and power you can be number one, no meaning at all.
This is not the GPU for gaming. But Intel kan ada, this year for low end budget really gooding.

ENDvidia in deep shit now.

technically one won't call that GPU also.. u just produce an ASIC with your customize logic, sure outperform any general purpose chip. unless of course u sucks at chip design and programming.

Innovative parallel computing design using domestic hardware underscores Beijing's broader strategy to blunt 'chokepoint' risks in critical tech

While sceptics caution that software tweaks alone cannot bridge hardware gaps indefinitely, the development underscores Beijing's broader strategy to mitigate "chokepoint" risks in critical technologies.

Scientists often rely on simulations to model real-world circumstances, such as designs to defend against flooding or urban waterlogging. But such reproductions, especially large scale, high-resolution simulations, demand substantial time and computational resources, limiting the broader application of such an approach.

The challenge for Chinese scientists is even more daunting. For hardware, production of advanced GPUs like the A100 and H100 are dominated by foreign manufacturers. On the software side, US-based Nvidia has restricted its CUDA software ecosystem from running on third-party hardware, thus hindering the development of independent algorithms.

In search of a breakthrough, Professor Nan Tongchao with the State Key Laboratory of Hydrology-Water Resources and Hydraulic Engineering at Hohai University in Nanjing, began exploring a "multi-node, multi-GPU" parallel computing approach based on domestic CPUs and GPUs. The results of their research were published in the Chinese Journal of Hydraulic Engineering on January 3.

The key to successful parallel computing is efficient data transfer and task coordination between multiple nodes, thereby minimising performance loss.

In 2021, Mario Morales-Hernandez and his research team at Oak Ridge National Laboratory in the US introduced a "multi-node, multi-GPU" flood forecasting model, known as TRITON, using the Summit supercomputer. Despite using 64 nodes, however, the "speedup" - or increased processing speed - was only around six times.

Nan proposed a new architecture that combined multiple GPUs into a single node, to compensate for the performance limitations of domestic CPUs and GPUs. At the same time, he improved data exchanges between nodes at the software level to reduce the communication overhead between them.

According to the paper, the model was set up on a domestic general-purpose x86 computing platform. The CPUs used were domestic Hygon processors, model number 7185 - with 32 cores, 64 threads, and 2.5 GHz clock speed. The GPUs were also domestic, supported by 128GB of memory and a network bandwidth of 200 Gb/s.

The new model reached a speedup of six with only seven nodes - about 89 per cent fewer than the number used by TRITON.

To validate the model's effectiveness and assess its computational efficiency, Nan's team chose the Zhuangli Reservoir in Zaozhuang, in east China's Shandong province, as the simulation subject.

Using 200 computational nodes and 800 GPUs, the model simulated the flood evolution process in just three minutes, achieving a speedup of over 160 times - far surpassing that of the TRITON model.

"Simulating floods at a river basin scale in just minutes means real-time simulations of flood evolution and various rainfall-run-off scenarios can now be conducted more quickly and in greater detail. This can enhance flood control and disaster prevention efforts, improve real-time reservoir management, and ultimately reduce loss of life and property," Nan said in the paper.

The code for the research is available on an open-source website. Nan added that the findings could be applied not just to flood modelling but also to simulations for complex systems in fields like hydrometeorology, sedimentation, and surface-water-groundwater interactions.

"Future work will expand its applications and further test its stability in engineering practices," he added.

So can I buy for rm500 and play games at 4K 120fps
If no then shut up

Code optimization from Chinese side is way more efficient than Nvidia.

Shame or not? Nvidia own multinational foreign talented coders are sleeping. Don't even know their own hardware well..

good

keep copy

moore thread boss were ex-nvidia if im not wrong.
amd gpu design team were in china previously (i think it still is).

removing china access to the data center focused card is stupid,it will just increase china rnd effort even more.

This is what happens when you have bad coding.

You need instead to buy a RM10k GPU just to play games at 4K 120fps when you should be able to enjoy similar performance with a 1/5 priced card?

Consumers say good but manufacturers say they'll earn less profit why not create a limited supply market and jack up prices?

Same goes to employer vs employee argument. Both have their interests.
