The K Computer, built by Fujitsu, currently combines 68544 SPARC64 VIIIfx CPUs, each with eight cores,

hahaha, these Japanese can't even make their own CPUs for their own supecomputers. They just put a large number of American CPUs together.

The Chinese are now putting their own Chinese designed CPUs into their own Chinese supercomputers. These Japanese need to learn from the Chinese.

These Japanese should stop wasting money on supercomputers, as they should help the poor Japanese people affected by their economic recession.

Anyway, Chinese supercomputers and Japanese supercomputers are way faster than Canadian computers.

hahaha, you need to understand that the Chinese are putting their own CPUs into their own laptops, computers and even supercomputers. The Chinese are now challenging the American monopoly in CPU market.
In the future, the Chinese no longer need to spend cash on American CPUs, with the potential of selling Chinese CPUs to other countries, thereby making money. Isn't that exciting?

The Japanese still can't make their own CPUs for their own supercomputers, so they need to use American products.

CERN is another different topic.

In other words, the Japanese don't know how to design their own CPUs, but still rely on SPARC, an American design.

You still got a very long learning curve.

The Japanese use SPARC from Sun Microsystem, an American design. They had to pay license fees. In other words, they don't have their own design.

The Chinese are now putting their own Chinese CPU design in their own supercomputers.

China to test own CPU in supercomputer

China will install CPUs developed by government-backed research institutions into a test supercomputer by the end of 2011.

The Loongson microchips will underpin the Dawning 6000 high-performance computing system, which is scheduled to be available for tasks as early as the summer of 2011, China's state-owned People's Daily Online publication reported on Monday.

"Our information industry was using foreign technology," Hu Weiwu, the chip's chief designer, said in the article. "However, just like a country's industry cannot always depend on foreign steel and oil, China's information industry needs its own CPU."

The Dawning 6000 will use up to 10,000 Loongson microchips and will eventually have a computing speed of "more than 1,000 trillion operations a second", according to Weiwu. 1,000 trillion operations are equal to a petaflop.

hahaha, the Japanese people can't even design their own CPUs, but have to buy the SPARC design from the Americans. Canadians just same, can't design their own CPUs.

peter236

hahaha, you need to understand this. The Chinese CPU's internal microarchitecture is designed by the Chinese themselves. China does not need to buy MIPS.

It is like AMD and Intel, both are different designs, but can run the same software.

But the Japanese can't design their own microarchitecture , so they have to buy the SPARC.

nah, China didn't buy any American design. The Japanese have to buy SPARC.

Chinese Godson 3c, 16-core version 32nm

Two other papers will give insights into China's growing silicon design sophistication.

The Chinese Academy of Sciences will detail the Godson 3c, a 16-core version of the China-grown processor based on the Mips64 instruction set. The new version, also known as the GS464V, includes 512-bit vector processing extensions and is made in 32nm technology.

"It's a big jump for them" compared to the previous four-core, 65nm version of Godson, said Renau.

"From what we saw in the abstract, they are aiming at video streaming and supercomputers because they are running benchmarks like Linpack and getting more than half a teraflop performance per chip with high energy efficiency for large scale systems," he said.

"I am envious they have so many students to develop a project like that," Renau added.

China's Dawning Computer recently designed the world's second fastest supercomputer using Intel Xeon and Nvidia graphics chips. Designers at Dawning said the company's next system will use the new Godson part.

In networking, China's Huawei Technologies will detail its work on a packet forwarding processor for routers that uses a novel memory technology.

"Huawei is becoming big in China, and competitive with Cisco Systems in some respects," said Renau. "This is one of the first times they are talking about something a couple years out," he said.

China's Godson MPU aims for 28-nm

A chief architect of China's microprocessor initiative described an ambitious set of new Godson CPUs including a server chip with vector processing and plans to leapfrog to a 28nm process for the next generation.

PALO ALTO, Calif. -- A chief architect of China's microprocessor initiative described an ambitious set of new Godson CPUs including a server chip with vector processing. Wei-wu Hu, a professor at Beijing's Institute of Computing Technology that has led development of the chips, announced several new 65 nm parts debuting in 2011 and plans to leapfrog to a 28-nm process for the next generation.

The ICT has developed six generations of the MIPS-based Godson chips since it started work on the architecture in 2001. Hu presented a paper at Hot Chips focusing on the latest high-end part, the Godson 3B.

The eight-core processor runs at up to a gigahertz and consumes 40W in a 65-nm STMicroelectronics process. The chip--which taped out in May and will be in silicon in September--measures 300 mm2 and delivers 128 gigaflops, Hu said.

The heart of the chip is the 64-bit, MIPS-compatible 464V core which sports a superscalar out-of-order pipeline capable of retiring four instructions per clock cycle. It supports 200 instructions to emulate the Intel x86.

The "V" in the core's name indicates the latest twist in the Godson design, extensions for vector processing.

The core extends its previous 64-bit floating point unit with a 256-bit SIMD vector unit including eight 64-bit MACs. Engineers also created a unique interface to feed the chip with pre-formatted data.

Hu provided little performance information for the part. However, he did say a single gigahertz core could decode H.264 video in 1080-pixel progressive resolution at up to 100 frames per second. The results are based on a combination of FPGA prototypes and RTL simulation.

The Godson 3B chip is currently in wafer testing. Researchers have yet to see the first packaged chips.

Hu showed several board-level examples of designs that will use the 3B in servers or as nodes in massively parallel supercomputing clusters. Earlier this year Shenzhen-based computer maker Dawning Information Industry Co. Ltd. created a petaflops system based on Intel and Nvidia processors and said its next generation will use the 16-core Godson 3C.

Hu suggested some of the Godson designs could hit performance levels of multiple petaflops—potentially putting China's designers in the number one slot on the list of the world's Top 500 supercomputers for the first time. The server chips also aim at design wins in high-end embedded systems.

A big leap behind the x86

Also on the road map is the Godson 2H, a single-chip PC processor that integrates graphics, a memory controller and a full suite of peripherals due in late 2011. Hu's group also plans a 16-core server chip for 2012, the Godson 3C.

The Godson paper created a buzz at Hot Chips where Hu was peppered with questions after his talk. However, some--including analyst Nathan Brookwood of Insight64 in a video interview--expressed skepticism whether China could make good on its ambitious plans, particularly for securing 28nm process technology.

The eight-core Godson 3B is in the works at a time when AMD is already shipping a 12-core server chip. Intel described at Hot Chips its Westmere-EX, a 32nm dual-threaded, ten-core server processor with advanced security and virtualization features it will ship soon.

China's CPU engineers plan to leapfrog 45nm process technology, using a 28nm process for their next generation design. Hu optimistically predicted he will have a prototype 28nm Godson design by April, though real products will not be ready until 2012.
