I appears to be very significant that China has achieved to build it´s first

- Petaflop class supercomputer.

It´s incredible to see how many leaps in technology capability has China maded in a time spam of only 20 years.

Tianhe-1, China's first Petaflop/s scale supercomputer

Fri, 2009-11-13 14:49
The Chinese National University of Defense Technology (NUDT) recently unveiled China’s fastest supercomputer, also the World Fifth fastest computer, which is able to do more than one quadrillion calculations per second theoretically at its peak speed.

The Tianhe-1(TH-1) supercomputer has been built by NUDT for NSCC-TJ. The TH-1 supercomputer system will be a key node linked into the national grid of China. The TH-1 system will be used to provide high performance computing service for the Tianjin area and the northeast of China. NSCC-TJ plans to use this system to solve the computing problems in data processing for petroleum exploration and the simulation of large aircraft designs. Other uses for the TH-1 supercomputer include the sciences, financial, automotive and shipping industries. The TH-1 supercomputer was installed in Changsha in the middle of 2009, and will be moved to NSCC-TJ soon.

The TH-1 system is a hybrid design with Intel Xeon processors and AMD GPUs. The TH-1 uses AMD GPUs as accelerators. Each node consists of two AMD GPUs attached to two Intel Xeon processors.

The TH-1 is made up of 80 compute cabinets including 2560 compute nodes and 512 operation nodes. There are two kinds of Intel processors used in the system, including 4096 Intel Xeon E5540 processors with a frequency of 2530MHz and 1024 Intel Xeon E5450 processors with a frequency of 3000MHz. The L1 cache size of the E5540 and E5450 processors is 128KB, the L2 cache sizes are 1MB and 12MB respectively. The E5540 processor has a L3 cache with the size of 8MB. Each compute node has two Intel Xeon processors with 32GB of memory. ATI Radeon HD 4870×2 GPUs are connected via PCI-E connections on each compute node. The maximum power recorded during the execution of LINPACK was 0.58KW per node. The Tianhe system used 20480 CPU cores (2 cpu*4 cores*2560 nodes) and 4096000 SPU (1600 Stream Processing Units* 2560 nodes) while executing the LINPACK benchmark. The cores of nodes not in operation whilst running the LINPACK benchmark were not included in the measurements. Each operation node also has two Intel Xeon E5450 processors and 32GB memory. The theoretical peak performance and the total memory of the whole system, which includes compute nodes and operation nodes, are 1.206PFlops and 98,304GB.

The compute nodes with E5540 processors are connected to 9 first-stage Infiniband switches. Each first-stage switch is connected to each second-stage switch through 18 uplinks, which makes a total of 72 uplink connections for 4 second-stage switches. The compute nodes with E5450 processors are connected by 64 Infiniband switch modules in the cabinets. Each switch module is connected to the second-stage switches through 8 uplinks.

The DGEMM and DTRSM, which are the core procedures of Linpack benchmark, are accelerated by cooperations of CPU and GPU on TH-1 system.

There are two processes located on each node. Each process is executed by a CPU and GPU pair. The three cores of CPU are used to execute part of the computing tasks, and the left core is used to control the GPU to participate the execution of computing tasks. The part of program executing on CPU uses the Intel MKL-10.2.1.017 library and the part of GPU uses the AMD ACMLG-1.0 library especially optimized by NUDT. The optimization algorithms used to achieve a better result of LINPACK benchmark are as follows.

First, dynamic load balance technique is used when allocating the tasks between CPU and GPU.
Second, the instruction of streaming load/store is adopted to reduce the conflict between CPU and GPU’s data accessing. The third, software-pipelining technique is used to overlap the execution of GPU and the transmission of data between GPU and CPU. The forth, affinity-scheduling technique is used to reduce the performance fluctuation by utilizing processor cores' computing and controlling ability. The fifth, we optimize the functions of DGEMM in AMD ACMLG library and DTRTRI and DTRMM in Intel MKL library to speed up the performance of DTRSM.
For the sake of the stabilization, the frequency of GPU core is decreased from 750MHz to 575MHz. Besides this, the frequency of GPU’s memory is also decreased from 900MHz to 650MHz.

i know that but much with much suffering of many peasants

Tell me... without a strong military, who is going to protect China from any invasion from other country? Without a strong military, who is to prevent the country from going back to the old warlord period of time and tell me how much more suffering is going to happen to normal peasants and civilians, whereby any one can come in and treat them like slaves.

I admit that there are quite a bit of corruption going on at the present moment and the main thing that the Chinese government is going to do... it is to quench these corruption, improve on medical and house care. But with the current GDP, I believe it is more than enough and they would still have enough for their military.

As compare to a few decades ago, I believe that living standards had already improved hughly and basically I do not believe that people are still starving to death in China.

Yes but an overpowered military can lead to a similar scenario in Japan in the '30s. Having big muscles might be fun, but I believe pen is mightier than the sword. Food, tackling poverty, and civic integrity in the systems and society are the primary concerns. Education and raising people's moral standards are extremely important, not to mention managing the distribution of wealth to backward and forgotten areas in China.

In fact China just need to remain as a counterbalance to US and it's already good enough to stay on equal level with the US military at this time.

IMO, China should spend only an appropiate amount of money into future military research after they have caught up with the US military. No offense to anyone, but I believe the US overdid their military. There is no "real" threat to the US that justify this tremendous budget to be spent on the armed forces, or this amount of firepower. And for the amount of money and resources spent beyond the necessary amount, they could've been spent on tackling domestic issues that requires attention or technology that better the life of the people. Example would be like the F-22, B-2, and the 16 supercarriers. The amount of wealth invested in there could definitely better the conditions of the red number US owes to foreign nation. And of course, for political gains, military can be useful. However once you can't even support what you have, that will be a trouble. Just imagine the amount of resources in all those aircraft boneyards and how they could be reused.

Anyways as for the topic.. in my mind nothing catches my mind more than the world modernization. But if China is really to invest in military technology, first I believe maybe they can further research on the rifle caliber of their standard issue. Next will be how to reuse or improve logistics and resources. If China can reduce consumption of resources for its military, this technology might also help in civilian areas. Also maybe China can look into its structure and improvise its organizational structure and to maximize efficiency and clarity.

As for air force, developing engines that release less exhaust not only reduce IR signals, but also can be used for civic technology in reducing pollution. Developing a modern supersonic strategic bomber with large range and low radar signature will be a very good project.

In cyber, developing a more secure and efficient system will ease management and security of information. Simpler civilian versions could be introduced to protect against anti-hacking and cyber warfare.

Reducing fuel and resource consumption of engines can also benefit the logistics side of things and the range of the all the war machines.

For the infantry, developing strong yet light equipment is also a very good. The resources developed here could also be used for civilian communities.

Also, military medical technology can benefit health care in China.

Having all the best gadgets doesnt necessarily make the army the best. Instead to furnish the structure and resources to optimal can make an army run like oiled engine in war.

China should research more on eletronic and cyber warfare. An enemy crippled by electronic battle just go blind, and you can beat him with any old weapon.

UK beat Nazi German in Battle of Britain because of their radar advantage, and they deployed their fighters in position before the Germans arrived at their target positions.

If you can render stealth fighters visible, an F-22 is no better than F-15. A navy fleet that can not communicate nor detect enemy are just sitting ducks.

Electronic and cyber superiority are the future.

China is right on track in that direction. The huge variety of ECM, AWACS of Y-8II platform produced has already make me lost count of it...

JH-7A fitted with electronic pod is also another great step forward.

What are you talking about? The average living standards of chinese rural folk have risen by magnitudes in the last 30 years. Sure, it's not a uniform rise, as some areas have benefited a lot more than other areas, but then, the Great Leap Forward and agricultural collectivization was an attempt at uniform, nation-wide progress, and look how well that turned out.

I have a question, inspired by the OP and too many hours of Fallout 3: would "power-armor" be actually of any use on the modern battlefield?

If anything, China's military should be focus on Sat Killing techniques, such as land lanuch missiles system, high power energy weapons, sea launch missiles and even air launch missiles system. I know that the Chinese had place a lot of emphasis in this area, and they are on the right track.

The most potent advarsaries in modern battle field is information relay. As mentioned by other posters in this forum, it is important to improve on the cyber capability of China, but I believe it is more important to just drop their satellites from space. And that would no doubt take away their eyes and ears.

The next thing they should do is develope a more comprehensive package against enemies AWAC, ELINT, spy planes and UAV. These would further blind their ground forces.

I agree.. Maybe Wakruo still got outdated data on China in the 80's to give him such conclusion??

In fact, China feat to drag so much people out of poverty in such a short time is hailed as a feat by many reporter or economist.

China has long out of the list of food aid in UN and become a major donate of food for other poor/poverish countries. More or less, it will tells you the living standard of its people.

Sat killing weaponry is pretty much targeted at one and only one adversary: the US of A. While it's a nice deterrent, as well as a diplomatic ace, it's doubtful that it will be of much practical use in itself. I simply don't see China going to war any time soon against US, or any other nation capable of fielding a satellite network.

On the other hand, China does have to worry about separatist insurgency movements and potential border troubles (*cough*India*cough*). Furthermore, China probably wants military capabilities that can help expand economic interests, and that means power projection and a blue-water navy.

So I see China's military development progressing on 3 fronts:

- Electronic and cyber warfare, and satellite killing weaponry for deterrence against more powerful adversaries (i.e. US)

- Counter-terrorism, counter-insurgency tactics. What would this involve?

- Power projection: it's doubtful any country would welcome a Chinese military base on its soil, so China will need to pursue both blue-water navy and soft-power projection to achieve this goal.

also cyber can allow steal of enemy information. a very useful thing to gather intel and even research without doing it yourself

and like others said up there, crippling opponents' information network and system will turn them into sitting ducks for Chinese plans
