India building a supercomputer juggernaut (hindu)

The as-yet-unnamed giant could win a spot in the top ten global list, and improve weather forecasting

Come June, India will likely unveil its most powerful supercomputer. If its processors operate at the full capacity of 10 petaflops (1 followed by 15 zeroes of floating point operations per second), a clock speed a million times faster than the fastest consumer laptops, it could earn a place among the world’s top 10 fastest supercomputers.
Though India has built or hosted supercomputers since the 1990s, it held a ‘top 10’ spot only once, in 2007, thanks to the EKA built by the Computational Research Laboratories, which is part of the Tata group. This position was lost, though several ultra-fast machines exist in Indian academic institutions: they feature in the 100s or 200s in global rankings.
The as-yet-unnamed machine will be jointly hosted at the Indian Institute of Tropical Meteorology, Pune and the National Centre for Medium Range Weather Forecasting at Noida in Uttar Pradesh.
For the first time, colleges and other research institutions can log in and harness its power to address problems, ranging from weather modelling to understanding how proteins fold. “The tender [to select the company that will build the machine] is ready and we hope to have it [the computer] by June” Madhavan Rajeevan, Secretary, Ministry of Earth Sciences, told The Hindu.

₹400 crore sanctioned

The government has sanctioned ₹400 crore for the project this year. Most of the machine’s computing power will help in monsoon forecasting, using a dynamical model. This requires simulating the weather for a given month — say March — and letting a custom-built model calculate how the actual weather will play out over June, July, August and September.
The processing speed of supercomputers is only one of the factors that determine its worth, with power usage and arrangement of processors, being other key metrics that determine the worth of a system.
Top500, the global authority tracking the fastest 500 computers, said in its latest report that China and the U.S. were “pacing each other for supercomputing supremacy.”

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”. The Supreme Court on Friday came close to ordering the government not to deport the Rohingya. It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests. The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach i...

"ISRO has capabilities to build geostationary satellites for air quality monitoring” (downtoearth)

Pawan Gupta's findings on trans-boundary movement of pollution (Punjab to Delhi) from biomass burning in 2015 spurred debates. He participated in discussions with Indian regulators early September at the Better Air Quality Conference in Busan on the advantages of using satellite data for air quality monitoring. He explains to Down to Earth how air quality monitoring is done using satellite data. How is satellite data used to measure air pollution? Satellites that provide information on atmospheric pollutants are normally (not always) in the low earth orbits (400-1000 km above the Earth’s surface). A single satellite can carry one or more remote sensing instruments onboard that look down to earth and obtain information about the object in the field of view of satellite sensor. The Earth receives electromagnetic radiation from the sun, which travels through space and reaches the earth-atmosphere system. The radiation then interacts with the Earth’s atmosphere and the surface...

What's ailing Namami Gange programme?(DTE)

Winters are extremely hectic for Sushma Patel, a vegetable grower in Uttar Pradesh’s Chunar town. Her farm is in the fertile plains of Ganga where people grow three crops a year. But this is the only season when she can grow vegetables. And before that, she needs to manually dig out shreds of plastic and wrappers from her one-hectare (ha) farm. “This is all because of the nullah,” she says, pointing at an open drain that runs through her field, carrying sewage from the neighbourhood to the Ganga. “Every monsoon, the drain overflows and inundates the field with a thick, black sludge and plastic debris. We cannot even go near the field as the stench of sewage fills the air,” she says. But Patel has no one to complain to as this is the way of life for most people in this ancient town. About 70 per cent of the people in Chunar depend on toilets that have on-site sanitation, such as septic tanks and pits. In the absence of a proper disposal or management system, people simply dump the faec...
