News on China's scientific and technological development.

Isn't it intentionally made that way for capital control?

Correct, however this makes any type of digital platform based out of China which tries to access international markets very difficult to setup.

American companies learn from their government. So much time has passed since the pompous announcement of "Build Back Better" and all we got is silence. The US hyped IPEF so much and the end result is a castrated TPP without trade. The US president promised to treat Saudi Arabia as a pariah state but now he is planning a trip there and his administration was crying about getting snubbed.

I think the combination of Trump and Biden is the perfect depiction of the US as a state - one side is a loud-mouth arrogant hillbilly who throws a fit whenever something does not go his way, the other is a demented declining old man who quickly forgets stuff he was preaching a minute ago.

Have you forgotten their "Vaccine Diplomacy" and the promised of providing money almost 10 years ago to countries in the Pacific Islands like Kiribati to be used for climate change related projects that has only received 10% of the promise funding. The U.S. and it's western vassals are all cattle and no beef. Loves to talk a great game but has failed to live up to their hype and fantasy like promises. Remember Mission Accomplished? Or how about they (America) will be greeted as liberators in Iraq lol...failure after failure and yet somehow China is overpromising? In @gadgetcool5 it's all projection of what America was, is currently and will always be until it's humbled by nature or man made.

But is China really so cowed by the West that it is afraid of announcing its own achievements? If so, what does that say about China's confidence?

Or does it pursue "yin" because it wants to give the illusion it has more achievements than it actually does? For the outsider, there is no way to tell the difference.

But in my view, China tends to over-announce and under-deliver. For instance, the C919 was supposed to be delivered by 2021.

Over-announce and under-deliver is a trait of one of China's neighbor, but not China. The type of delay experienced by C919 is more of an exception than the norm due to Western roadblocks and sanctions.

Just want to make it clear to everyone that as far as supercomputer is concerned, China did not and does not hide anything about the status of their exa-scale computer development.

In the past few years, Chinese scientists kept the international scientific community appraised on China's exa-scale computer plan and development, including how many and where such systems are being built, by publishing papers and giving international presentations.

Last year numerous peer review scientific papers have been published on selected applications being done on two completed exa-scale computers. China just chose not to enter those computers into the Top500 contest.

In such research papers, the authors have to detail the architecture of the computer, the algorithm and its implementation, and the performance of the computer relative to the application etc.

While to be considered for Top500 competition, the participants must also provide the name and vendor of all key subsystems and components of the computer. It is for this reason and the sanction risk to those suppliers, especially the domestic ones, that China chose not to enter them into the Top500 competition.

I hope some forum member here refrain from making stupid assertions based on ignorance and ideology.

@gadgetcool5 is indeed actually describing India supapowa 2020 and all their helium filled like pronouncements. Just recently their supposed 157 air craft acquisition has been whittled away to a mere 56 aircraft with the insistence and expectations of TOT. The announcements and super delayed from their Arjun tanks, the best ever super indigenous INS Vikrant, super duper fighter plane Tejas etc...

China is essentially damned regardless of how it chooses to conduct itself. The only acceptable circumstances from these folks is China's subservience to American interests which will never f..ng happen.

Most civilian jet liner program suffer delay just follow the US or Japanese program!

Now Boeing want to cut cost and speed up the production of Max 737 The result is crash!


The more I studied the crash, the more I realized the media wasn’t telling the full story. That’s the purpose of this essay.

Why did the 737 Max crash? Because of a software failure.

Why did the software fail? Because Boeing’s executive team has lowered its engineering standards.

Why did Boeing lower its engineering standards? To lower costs and increase efficiency — the goal was to save money.

By the Western mentality that you ascribe to, are you really so cowed by me that you're afraid to answer any of my rebuttals? If so, what does that say about your confidence?

If you manage to grow something that resembles a spine:

Also, you said soon like 3 weeks ago and things don't seem to be moving in that direction at all so don't forget to let us know the date on this as well:

No, these computers use Chinese designed chips and components but it’s because the US will strong arm TSMC to stop making these chips for them. Obama prevented Intel and other US companies from selling chips for Chinese supercomputers but China was still able to make them using their own chips but still need tsmc to make them.

Bollox. Sunway architecture is not made at TSMC. At most you might claim that for Phytium, but I guess they learned their lesson by now.

Really? I thought Sunway and phytium needed TSMC. Who makes Sunway chips? And how does phytium get their chips made now? I wasn't able to find any info on it

Sunway architecture is supposedly similar to something like IBM Cell. i.e. you have a 64-bit controller RISC core, and then you have a bunch of worker cores with SIMD vector units. It is an architecture built for peak FP compute. With an architecture like that you can use an older manufacturing process and get same or better peak FP compute than with a general purpose core design on a newer process. An architecture like that requires less transistors.
