United States, China, Europe and Japan race to the Exaflop Supercomputer


Yeah these officials who have approved the projects should get a whip in the butts if they are found out for wasting / under-utlizing precious resources

An example for this SuperComputer Tianhe 1 - former world champion, one of the best in world. The project was approved in 2010 but constructions and project delayed has caused the officiating of its full operation just last week:

I hope there are not too many of those. We have a total of 61 supercomputers on Top500 (Nov 2014) . Some of those are ranked as the first and amongst the best in world.

If we are not using them to targeted capacities we may consider selling them out to reduce the carrying costs :dirol:

The rating was given by Supercomputing Conference (SC 2013).
We are doing well in many collegiate competitions in regional and international supercomputing like those held in SC 13, SC 12, SC 11 ...etc :china: Sorry to see Indians are keeping quite anonymous profiles in those events. :coffee::cheesy:

Here is the list of the world's top 100 energy-efficient “supercomputers”:

The Green500 List - June 2014 | The Green500

It is evident that the top-ranked are not really “supercomputers” with total power only in the tens of KWs。

It is also clear that the vast majority of the systems with total power in the hundreds or thousands of KWs has a Gflop/W figure of near or less than 1.

China's Tianhe-2 stands out with a power-efficiency of 1.9Gflop/W for a total power of 17808 KW, by far the highest.
I heard japan developed most energy efficient super computer which performs 5g/w .. Which means 5 exa per 1000 mw
I dont understand why you are thinking that it cant be bettered ...Adding cluster of cpus is not only development ,research is going on to make efficient processors (speed and energy efficient) ..lets wait and see what will happen in future
 

"India is superpower!! even if its only in our wettest dreams. we will claim to do this and do that but it will always be in the future tense because india is the superpower of the future and always will be"
- A senior top indian policy maker

my post is as valid as your because they both list an unknown, unverified source.

now on to this 132 exaflop HPC

i will say right now, and few free to quote me for use in the future, India will not have a 132 exaflop HPC by the end of 2020, i will go further and say, they will not have 1% of the performance of a 132 exaflop HPC by 2020. Everyone who is anyone in term of HPC powers are aiming for about 1 exaflop by 2020 and somehow we're suppose to believe india which is barely a HPC power can outclass nations like japan, US and China by a factor of 132?
 
At least this news has some sort of semblance, but what about the news purporting a Chinese submarine reaching USA within 2 hours?

Lol..

China says new supersonic sub would reach San Francisco in 100 minutes
FYI, that claim originally came from a report published by South China Morning Post(SCMP) from Hong Kong. Citing source from unnamed Chinese mainland military insider.

Within a week of the report, the very institute and professor mentioned, that has published scientific paper on supercativation has denied on Chinese media that they has ever make the kind of claim headline in SCMP report. They only make the claim that they had outlined in their scientific paper.
 
China's Tianhe-2 takes 4th fastest supercomputer crown

For the fourth consecutive time, Tianhe-2, developed by China's National University of Defense Technology, has retained the top spot as the world's fastest supercomputer, according to a biannual Top500 list of supercomputers released on Monday.

The updated list came on the heels of an announcement Friday by the U.S. Department of Energy (DOE) that it will spend 325 million U.S. dollars on building two supercomputers, which will be three to five times faster than Tianhe-2.

Although the United States clearly wants to regain the supercomputing crown from China, Jack Dongarra, professor of the University of Tennessee and Top500 editor, insisted that there is no connection between the two announcements.

"The (U.S.) systems will be operational in 2018. It's just a coincidence," Dongarra wrote in an email to Xinhua, adding that there will be additional announcements to come from the DOE.

And before that, there will be no machine that can dethrone the Chinese supercomputer, he said.

Tianhe-2, which means "Milky Way-2" in Chinese, can operate at 33.86 petaflops per second (Pflop/s), the equivalent of 33,860 quadrillion calculations per second.

The National Supercomputer Center in Guangzhou in south China, where Tianhe-2 is installed, is reportedly making an update to increase the system's speed to more than 100 Pflop/s.

Titan, installed at the DOE's Oak Ridge National Laboratory, remains the No. 2 system with a performance of 17.59 Pflop/s. Sequoia, installed at the DOE's Lawrence Livermore National Laboratory, is again the No. 3 system with a performance of 17.17 Pflop/s.

Japan's K computer is the No. 4 system with 10.51 Pflop/s, followed by Mira, installed at the DOE's Argonne National Laboratory, which has a performance of 8.59 Pflop/s.

In fact, the top10 list was almost the same as the one published six months ago. The only new entry was at number 10, a 3.57 Pflop/s Cray Storm system installed at an undisclosed U.S. government site.

"These machines in the top10 are very expensive and provide extreme computing power. Perhaps we have enough computing power for the moment and not enough funding for the next generation just now," Dongarra said, noting that the interest and need by science for these systems and more powerful systems will not end.

In terms of overall systems, the United States remains the top country with 231, but this number is down from 233 in June 2014 and down from 265 on the November 2013 list, nearing the country's historical low number on the list.

China still occupies the No. 2 position as a user of supercomputers, ahead of Japan, Britain, France, and Germany. But the number of systems installed in the Chinese mainland has fallen to 61, compared with 76 on the previous list.


The Top500 list is considered one of the most authoritative rankings of the world's supercomputers. It is compiled on the basis of the machines' performance on the Linpack benchmark by experts from the United States and Germany.

Yes !

Small “supercomputers” tend to be more energy efficient than true supercomputers。

A benchmark of the most energy efficient true supercomputers is China's Tianhe-2 with 1.9Gflops/W 。

Of course the energy efficiency of supercomputers can be bettered。And it will be。

But even if the current benchmark is bettered by a factor of 15 over the next 5 years,India's 132 exaflop monstrosity would still require a power plant with enough generating capacity for the electrical needs of 2 Mumbais。
