‘Approximate computing’ improves efficiency, saves energy This article is republished from The Conversation under a Creative Commons license. Read the original article. When the cryptocurrency mining company Hut 8 opened Canada’s largest bitcoin mining project outside Medicine Hat, Alta., environmentalists sounded the alarm. The plant consumes 10 times more electricity, largely produced by a natural gas-fired power plant, than any other facility in the city. Globally, greenhouse gas (GHG) emissions from the information, communication and technology (ICT) sectors are forecast to reach the equivalent of 1.4 gigatonnes (billion metric tonnes) of carbon dioxide annually by 2020. That’s 2.7 per cent of global GHGs and roughly double Canada’s total annual greenhouse gas output.By designing energy-efficient computer processors we could reduce energy consumption, and we could reduce GHG emissions in places where electricity comes from fossil fuels. As a computer engineer specialized in computer architecture and arithmetic, my colleagues and I are confident these positive effects can be achieved with almost no impact on computer performance or user convenience. Powerful connectionsThe Internet of Things (IoT) —made up of the connected computing devices embedded into everyday objects —is already delivering positive economic and social impacts, transforming our societies, the environment and our food supply chains for the better. These devices are monitoring and reducing air pollution, improving water conservation and feeding a hungry world. They’re also making our homes and businesses more efficient, controlling thermostats, lighting, water heaters, refrigerators and washing machines. With the number of connected devices set to top 11 billion —not including computers and phones —in 2018, IoT will create big data requiring huge computations.

In computing, energy use is often considered a secondary problem to speed and storage, but with the rate and direction of technological advancement, it is becoming a growing environmental concern. Provided by The Conversation Making computation more energy efficient would save money and reduce energy use. It would also allow the batteries that provide power in computing systems to be smaller or run longer. In addition, calculations could run faster, so computing systems would generate less heat.Approximate computingToday’s computing systems are designed to deliver exact solutions at a high energy cost. But many error-resilient algorithms like image, sound and video processing, data mining, sensor data analysis and deep learning do not require exact answers.This unnecessary accuracy and excessive energy expenditure is wasteful. There are limitations to human perception —we don’t always need 100 per cent accuracy to be satisfied with the outcome. For example, minor changes in the quality of images and videos often go unnoticed. Computing systems can take advantage of these limitations to reduce energy use without having a negative impact on the user experience. “Approximate computing” is a computation technique that sometimes returns inaccurate results, making it useful for applications where an approximate result is sufficient. At the University of Saskatchewan’s computer engineering lab, we are proposing to design and implement these approximate computing solutions, so that they can optimally trade off accuracy and efficiency across software and hardware. When we applied these solutions to a core computing component of the processor, we found that power consumption dropped by more than 50 per cent with almost no drop in performance.Flexible precisionNowadays, most personal computers contain a 64-bit standard numerical format. This means that they use a number with 64 digits (either zero or one) to perform all the computations. 3-D graphics, virtual reality and augmented reality require the 64-bit format to work. But basic audio and image processing can be done with a 32-bit format and still provide satisfying results. Moreover, deep learning applications can even use 16-bit or 8-bit formats due to their error resilience The shorter the numerical format, the less energy is used to perform the calculation. We can design flexible, yet precise, computing solutions that run different applications using the most appropriate numerical format so that it promotes energy efficiency. For example, a deep learning application using this flexible computing solution could reduce energy consumption by 15 per cent, according to our preliminary experiment. In addition, the proposed solutions can be reconfigured to simultaneously perform multiple operations requiring low numerical precision and improve performance. The IoT holds a great deal of promise, but we must also think about the costs of processing all of this data. With smarter, greener processors we could help address environmental concerns and slow or reduce their contributions to climate change. Explore further This document is subject to copyright.

Uber wants to be at the forefront of the driverless car revolution Explore further © 2019 AFP The latest cash injection, expected to close in the third quarter this year, came amid fevered anticipation of Uber’s public share offering which is expected to be the largest in the tech sector for years.Toyota has already invested $500 million in Uber as the firm races Google-owned Waymo and a host of other companies, including major automakers, to develop self-driving vehicles.The latest investment, which also involves Japanese parts maker DENSO, will go to Uber’s Advanced Technologies Group in a bid to “accelerate the development and commercialisation of automated ridesharing,” the firms said in a statement.Toyota and DENSO are stumping up $667 million and SoftBank Vision Fund, the investment arm of Japanese tycoon Masayoshi Son’s SoftBank, will pour $333 million into the venture. It is already the top shareholder in Uber, holding 16 percent.The Japanese car firm said it would also contribute “an additional $300 million over the next three years to help cover the costs related to these activities.” Uber chief executive Dara Khosrowshahi said driverless cars would “transform transportation as we know it, making our streets safer and our cities more liveable.”His firm is aiming to go beyond car rides to becoming the “Amazon of transportation” in a future where people share, instead of own, vehicles.If all goes to plan, commuters could ride an e-scooter to a transit station, take a train, then grab an e-bike, share a ride or take an e-scooter at the arriving station to complete a journey—all using an Uber app on a smartphone.Uber is also seeing growing success with an “Eats” service that lets drivers make money delivering meals ordered from restaurants.’Sharing economy’Last week, Uber filed official documents for its much-anticipated public share offering.The filing with the Securities and Exchange Commission said it operates on six continents with some 14 million trips per day and has totalled more than 10 billion rides since it was founded in 2010.The filing contained a “placeholder” amount of $1 billion to be raised but that figure is expected to increase ahead of the initial public offering (IPO) expected in May.The Wall Street Journal said earlier this month that Uber was seeking to raise $10 billion in what would be the largest stock offering of the year.Media reports said the ride-hailing giant was likely to seek a market value of close to $100 billion.Uber is the largest of the “unicorns” or venture-backed firms worth at least $1 billion to list on Wall Street, and is one of the key companies in the “sharing economy” based on offering services to replace ownership of cars, homes and other commodities.Its revenue grew 42 percent last year to $11.2 billion but it continued to lose money from its operations. A net profit was reported for the year from a large asset sale, but operational losses were more than $3 billion.And some analysts have voiced caution over the forthcoming IPO given a relative lacklustre debut for Lyft, the main US rival.Khosrowshahi has promised greater transparency as he seeks to restore confidence in the global ridesharing leader hit by a wave of misconduct scandals.In October, Toyota and SoftBank announced the creation of a joint venture to create “new mobility service” including driverless vehicles for services such as meal deliveries.The new company—called “Monet”, short for “mobility network”—is majority owned by SoftBank.SoftBank started as a software firm but has increasingly been pushing into investments under tycoon Son, one of Japan’s richest men. Japanese car giant Toyota and investment fund SoftBank Vision Fund on Friday unveiled an investment of $1 billion in US company Uber to drive forward the development of driverless ridesharing services.
