See the talk here is already way off of supercomputer already. Not my fault.

I am not blaming you. I just hope that, after the 'pollution' ends, we should all show some respect to the PDF rule: derail not allowed.

Let get back to business.
There are currently three competiting domestic CPU that will power the 100+ petascale supercomputer, ShenWei, Loongson Godson, and Phytium Mars. Each has its own unique architectural design, Shenwei is RISC , Loongson is MIPS, and Phytium Mars is ARM-based design. So it is very interesting time ahead. Right now ShenWei 4th gen CPU is powering Sunway TaihuLight and I heard they got a 5th gen done ready to power up the 200-300 petaflops supercomputer. We will see which design is best at powering our next exascale supercomputer in 2020 as these three competing cpu architectural design is optimal for exascale. It is always good to see intense competition among our cpu scientist. As far as which design can be used on commercial computer, the desktop at your home so to speak, then I gotta go with Loongson Godson because MIPS instruction can be translated with an emulator read x-86 architectural instruction set so that means commercial OS, Window-based and iOS operation system, can be useful on Godson cpu.

you forgot this dsp chip to be used in tianhe-2a
--
Dr Lu, who leads the design of China's Tianhe supercomputers, said homegrown digital-signal processors (DSPs) will power the upgrade to the Tianhe-2A super, our sister website The Platform reports. Dr Lu revealed the development at the International Supercomputing Conference in Germany on Wednesday.
The boosted Tianhe-2A is due to go live before the end of 2016, and is apparently expected to perform 100PFLOPs – 100,000 trillion calculations per second – at its peak. It will, according to Dr Lu, consume up to 18MW of power, pack about three petabytes of system RAM, and use Intel Xeon E5-2692 processors from the Tianhe-2 plus the new homegrown accelerators.
Today's Tianhe-2 – the world's most powerful publicly known supercomputer – uses a mix of E5-2692 CPUs and Xeon Phi accelerators. Essentially, the 2A will use the China-crafted DSPs instead of the Phis, alongside the Xeon E5 processors, it appears. The Tianhe-2A will be built from 18,000 nodes, and run off a 30PB file system, we're told.
The Matrix2000 DSPs are 1GHz 64-bit chips, they draw 200W of power, and can perform 4.8TFLOPS of single and 2.4TFLOPS of double precision math. They are interfaced using x16 PCIe 3.0 links, and performance-wise, give GPUs and the Phi a run for their money.
"The Tiahne-2 machine (and its eventual successor sporting the DSP accelerators) is housed at the National University of Defense Technology (NUDT) in China," The Platform co-editor Nicole Hemsoth reports.

Who the hell is Phytium? Never heard of their chips before. Is Chinese HPC chip business about to experience a period of exponential growth and then Chinese are going to sell their HPC chips by pound? It would be fun to see Chinese supers take over top spots on top500 list in a few years with 4 different kinds of Chinese home brewed HPC chips.

China Shakes Up ARM Servers
64-core chip leapfrogs competition
Rick Merritt
8/25/2015 08:00 PM EDT
Hot Chips event here the most aggressive ARM-based server processor to date. In the same session, Oracle described its first Sparc processor with integrated Infiniband.
Little known Phytium Technology Co. Ltd., founded in 2012, described a processor using 64 custom ARMv8 cores that will run at up to 2 GHz at 28nm. It can issue up to four instructions per cycle to hit up to 512 GFlops. The massive chip consumes 120W and fits in a 640mm2 die with about 3,000 pins.
The so-called Mars design surpasses existing high-end ARM-based server chips such as the 48-core ThunderX now sampling from Cavium and a high-end part still in the works at Broadcom. In February EZchip said it will ship a 100-core ARMv8 made in a 28nm process, but it may not ship until 2017.
The Mars design has not yet taped out, but nevertheless impressed analysts and observers at the annual gathering of microprocessor designers here, in part because few had heard of the company.
Like IBM's Power 8, Mars uses external L3 cache and memory controllers.
“My God, who knew…this is by far the most aggressive 64-bit ARM chip to be announced – it’s just awesome, and it was definitely the surprise of this event,” said Nathan Brookwood, principal of Insight64 (Saratoga, Calif.).
Sam Naffziger, a fellow at AMD who moderated the session, called Mars a respectable design with a “good cache hierarchy and good bandwidth match.”
Hot Chips organizers were surprised to get a paper proposal from Phytium, a company they had not heard from previously. It had accepted several papers in the past from a China government- and university-backed team building the so-called Godson processor.
“I was surprised we didn’t hear from [the Godson team] again this year,” said Ralph Wittig, a Hot Chips organizer. “When we got the Phytium paper we heard from ARM they were confident the startup was doing real stuff…their external memory modules are like IBM;s work on Power 8…we were highly impressed as a program committee,” Wittig said.
Adding to the mystery, a Phytium engineering manager was not able to get a U.S. visa in time for the event. He presented his slides by phone from China where the company has offices in Tainjin and Guangzhou.
One attendee familiar with Phytium said the team was not from the Godson project. The company’s Tianjin offices did suffer broken glass and shrapnel from the recent explosions there, he said.
In simulations on the SpecCPU 2006 rate benchmark, Mars hit 672 in integer and 585 in floating-point performance for a 64-core chip. However, observers noted its scaling from single-core performance was modest.
The chip is organized into eight-core panels in which four cores share a 4-MByte cache. Eight external chips provide a total of 128 Mbytes L3 cache and 16 DDR3-1600 channels.
Phytium’s custom 64-bit ARM core has 192 physical registers. A reorder buffer can hold up to 160 instructions, and about 210 instructions can be in-flight in the overall pipeline.
Phytium designed its own 64-bit ARM core code-named Xiaomi.
The chip dispatches and retires instructions in-order and executes them out-of-order. It uses an aggressive branch predictor and implements multithreading.
Mars supports MPI and Open MP interfaces for multiprocessing systems. Another processor in the works, called Earth, will be a lower cost, lower power device aimed more at today’s large data center
“I’m pretty sure [Mars] will be the first 64-core ARMv8 processor in the world,” said Charles Zhang, director of research for Phytium, speaking via a phone line to Hot Chips attendees. “It’s a good beginning…in next few years we will develop more powerful CPUs,” he said.
One of the biggest drawbacks of Mars is its size, said analysts. Achieving good yields on such a large chip will be difficult, they noted.

Now this startup is a real thing! I thought NUDT was working on Matrix2000.

how is it fraudulent
the achievement is the amount of satellites put into orbit not the weight of them

It would be an exiting time to see competing cpu architectural design get put to the test at the highest level of computation. We are the only one in the world to test multiple chip design on a supercomputer thanks in part to the stupid ban. LOL
it's both main and co-processor like xeon phi and nvidia tesla. you can build a super computer with just those type of processors like the new 25pf currently in development by fujitsu

I don't consider that worthy of celebration.
