China wins supercomputer crown for eighth time

November 16, 2016

Beijing, Nov 16: For the eight consecutive year, China has retained the top spot in the list of the world's fastest supercomputers for its 'Sunway TaihuLight' which can perform 93 million billion calculations per second, media report said today.

chinaTaihuLight, the massive supercomputer, built entirely using processors designed and made in China has been crowned as the world's fastest, state-run Xinhua news agency quoted the latest edition of the semiannual Top500 list of supercomputers released on Monday.

TaihuLight made its appearance in June, replacing the former champion, Tianhe-2, also a Chinese system but built based on Intel chips. TaihuLight is capable of performing 93 million billion calculations per second (petaflop/s).

That is almost three times as fast as Tianhe-2, which had claimed No 1 spot in the Top500 list for the past three years.

That means a Chinese supercomputer has topped the rankings for eight times in a row, indicating the rise of China in the high performance computing (HPC) field, the report said.

In the previous list released in June, China overtook the US in the number of total supercomputers installed. That was the first time that the US has not dominated this category since the list was started 23 years ago.

This time, the number of systems installed in China increased to 171 from 168 on the last list.

"The 48th edition of the Top500 list saw China and the US pacing each other for supercomputing supremacy," Top500 editors said in a statement released at an HPC conference in Salt Lake City.

In addition, China and the US are "neck-and-neck in the performance category" with the latter holding 33.9 per cent of the overall installed performance while the former is second with 33.3 per cent of the overall installed performance, said the statement.

In the latest rankings, Titan and Sequoia, two systems from the US, remained No 3 and No 4 positions. The Cori supercomputer, a new system installed at the US Lawrence Berkeley National Laboratory, slipped into the fifth slot with a performance of 14.0 petaflop/s, the report said.

When it comes to companies making these systems, the America-based Hewlett-Packard Enterprise has the lead with 112 supercomputers, which is followed by China's Lenovo with 92 systems.

There are three other Chinese companies in the vendor list: Sugon (No 4 with 47 systems), Inspur (No 8 with 18 systems) and Huawei (No 9 with 16 systems). The Top500 list is considered one of the most authoritative rankings of the world's supercomputers.

Thiruvananthapuram, Mar 12: In the wake of COVID-19 outbreak, Internet service providers in Kerala have agreed to step up the network capacity by 30 to 40 per cent of the present capacity to meet the demand, especially in view of the spurt in work-at-home mode.

"The decision was made at a meeting of representatives of various telecom service providers in Kerala circle and officials of the Telecommunication Department convened by the Secretary, Electronics and IT, following a direction by Chief Minister Pinarayi Vijayan to look into the issue," said a press release by the IT Department.

The decision will be beneficial for those working in IT institutions. The government has come out with a set of suggestions to avoid social gatherings at public places in view of coronavirus spread. Telecom service providers have assured the government that they are well equipped to face the current situation.

The major part of Internet consumption in Kerala is made available through local servers. Moreover, global Internet traffic is very low as compared to the overall consumption. So, increasing the capacity won't be difficult, service providers informed.

"Complaints regarding the low availability of the Internet due to the spurt in consumption of the Internet can be made to the service providers to their complaint redressal number or inform state government call centre (155300). But complaints regarding the insufficiency in the current network infrastructure should be strictly avoided," said the release.

The IT Department will also demand daily reports from various telecom service providers. By analysing these reports, steps for remedies will be taken after bringing the sudden increase in consumption to the service providers.

The Brazilian government said that the Amazon rainforest witnessed deforestation of a record 829 sq km in May, the highest monthly level since 2015.

On Friday, the National Institute for Space Research (INPE) said that deforestation in the Amazon increased by 91 sq km compared to the same period last year, reports Xinhua news agency.

Between January and April, destruction of the forest by illegal loggers and ranchers rose 55 per cent, or a total of 1,202 sq km was wiped out, it said.

The Real-time Deforestation Detection system, a federal project created to monitor human activity in the Amazon, alerted authorities to the increase in the rate of destruction of the rainforest.

A recent study by the Amazon Environmental Research Institute (IPAM) warned that deforestation in 2020 could reach 11,900 sq km if the pace of May, June, and July follows the historical average.

Deforestation in the region has soared since President Jair Bolsonaro took office last year, according to conservation groups.

He has argued that more farming and mining in protected areas of the forest were the only way to lift the region out of poverty.

Bolsonaro's environmental policies have been widely condemned but he has rejected the criticism, saying Brazil remains an example for conservation.
