Enter the (Big) Dragon

As part of my continuing service to report on the fascinating developments in the Chinese chip sector, I pass on the following:

It's official: China's next supercomputer, the petascale Dawning 6000, will be constructed exclusively with home-grown microprocessors. Weiwu Hu, chief architect of the Loongson (also known as "Godson") family of CPUs at the Institute of Computing Technology (ICT), a division of the Chinese Academy of Sciences, also confirms that the supercomputer will run Linux. This is a sharp departure from China's last supercomputer, the Dawning 5000a, which debuted at number 11 on the list of the world's fastest supercomputers in 2008, and was built with AMD chips and ran Windows HPC Server.

It won't come as a surprise to readers of this blog that China's new supercomputer will be running Linux - over 80% of the world's big machines do. What's fascinating is that this is being built out of that home-grown Loongson chip - the one that Windows doesn't run on. As the same article explains:

The arrival of Dawning 6000 will be an important landmark for the Loongson processor family, which to date has been used only in inexpensive, low-power netbooks and nettop PCs. When the Dawning 5000a was initially announced, it too was meant to be built with Loongson processors, but the Dawning Information Industry Company, which built the computer, eventually went with AMD chips, citing a lack of support for Windows, and the ICT's failure to deliver a sufficiently powerful chip in time.

That means that as China builds more and more of these, and pushes the technology further and further, it will be Linux that benefits, not Windows, and Linux that spreads...

China + Loonson + Linux: this is one to watch...

What Took Wired So Loongson?

I've been writing about the Loongson chip for three years now. As I've noted several times, this chip is important because (a) it's a home-grown Chinese chip (albeit based on one from MIPS) and (b) Windows doesn't run on it, but GNU/Linux does.

It looks like Wired magazine has finally woken up to the story (better late than never):

Because the Loongson eschews the standard x86 chip architecture, it can’t run the full version of Microsoft Windows without software emulation. To encourage adoption of the processor, the Institute of Computing Technology is adapting everything from Java to OpenOffice for the Loongson chip and releasing it all under a free software license. Lemote positions its netbook as the only computer in the world with nothing but free software, right down to the BIOS burned into the motherboard chip that tells it how to boot up. It’s for this last reason that Richard “GNU/Linux” Stallman, granddaddy of the free software movement, uses a laptop with a Loongson chip.

Because GNU/Linux distros have already been ported to the Loongson chip, neither Java nor OpenOffice.org needs "adapting" so much as recompiling - hardly a challenging task. As for "releasing it all under a free software license", they had no choice.

But at least Wired got it right about the potential impact of the chip:

Loongson could also reshape the global PC business. “Compared to Intel and IBM, we are still in the cradle,” concedes Weiwu Hu, chief architect of the Loongson. But he also notes that China’s enormous domestic demand isn’t the only potential market for his CPU. “I think many other poor countries, such as those in Africa, need low-cost solutions,” he says. Cheap Chinese processors could corner emerging markets in the developing world (and be a perk for the nation’s allies and trade partners).

And that’s just the beginning. “These chips have implications for space exploration, intelligence gathering, industrialization, encryption, and international commerce,” says Tom Halfhill, a senior analyst for Microprocessor Report.

Yup.

Jisus - It's the Loongson Chip

Aside from its rather curious name, the Jisus ultraportable seems at first sight pretty standard:

* Monitor: 8.9” LCD screen (800×480 pixels), LED backlight, VGA port
* Processor: 1 GHz, 64-Bit Loongson 2F
* Graphics: SM712
* Memory: 512 MB DDR2-667
* RAM: 4GB Nand flash
* Operating system: Ubuntu, others possible

But closer inspection reveals something unusual: the use of the Loongson chip. As I've noted before, what makes this notable is that it's produced in China, using a non-standard architecture. Although there are claims that Windows CE has been ported to it, it's mainly used to run GNU/Linux. All of which makes it perfect for ultraportables. It will be interesting to see whether it turns up elsewhere. (Via Eee Site.)

Loongson: GNU/Linux's Longshot

One of the under-appreciated strengths of GNU/Linux is its wide platform support. So what? you might sniff: the only platform that matters is Intel's. Well, yes - at the moment. But that could change courtesy of those nice people in the Middle Kingdom.

For Loongson - which readers will remember, is a Chinese chip company that has built a microprocessor surprisingly similar to one produced by MIPS - is hoping that Chinese government support will make its architecture rather important:

Once Loongson chips can meet basic demand, China plans buy them for its army, government offices, and public education. In addition, some local governments have been purchasing computers for China's rural areas to demonstrate the achievement of the "new country construction." It's estimated that China's rural areas will utilize at least 6 million computers in 2007 and 2008, giving Loongson a big boost in this arena.

Why is this good news for GNU/Linux? Because Loongson chips cannot run Windows - there is no MIPS port for XP or Vista. But there is already one for GNU/Linux, which is, amazingly enough, precisely the OS that those 6 million future machines (if they materialise) will be running. Hen hao.

The More Than Middling Middle Kingdom

The news that the Chinese Lemote Technology Corporation has released its first PCs based on the Loongson/Godson chip is interesting for a number of reasons. First, because the chip was designed and made entirely in China, making the country independent of Western chipmakers; and secondly, because as a non-standard chip architecture, the new chip can't run Windows. Which, means, almost inevitably, that it runs GNU/Linux. If China wants to be truly independent, free software is the quickest and easiest way to do it.
