Toward Sustainable Networking

Figure 1: Estimation of expected total annual energy   consumption per IT industry in the period 2010–2030. The plethora of data generated by scientific applications, the Internet of Things, social media, and e-commerce fuel large-scale data analytics systems. As a result, data transfer over the Internet has been increasing each year exponentially and has already exceeded the zettabyte scale. With the increased data generation rate, the data movement’s carbon footprint is becoming an overwhelmingly critical problem, especially for data centers and wired access networks. It is estimated that information and communication technologies will use between 8% - 21% of the world’s electricity by 2030 . The estimation of expected total annual energy consumption per different IT industries in the period 2010–2030 is shown in Figure 1. The share of data centers and communication networks in the total IT power consumption is 69%. Among this share, the data transfers alone consume over a hundred

A Vision for a National Data and Software Cyberinfrastructure

During my term as an  NSF  program director in the  Office of Advanced Cyberinfrastructure between 2020-2022, I had the opportunity to lead the development of  NSF’s Blueprint for a National Data and Software Cyberinfrastructure .  This blueprint document is publicly available to the community and provides a forward-looking vision for a robust, secure, trusted, performant, scalable, and sustainable data and software cyberinfrastructure (Data and Software CI) ecosystem to enable and accelerate science and engineering research. This blueprint was prepared based on a comprehensive analysis of existing NSF programs and a wide range of input from the community via advisory bodies, requests for information (such as Data-Focused   Cyberinfrastructure Needed to Support Future Data-Intensive Science and Engineering Research  and Future Needs for Advanced Cyberinfrastructure to Support Science and Engineering  Research ), community surveys (such as NSF CSSI Community Survey ), and several NSF-f

Toward Sustainable Software for HPC, Cloud, and AI Workloads

Software applications are considerable consumers of computing resources, leading to a significant carbon footprint. Recent estimates suggest that Information Technology accounts for approximately 11% of global energy consumption . Projections indicate that by 2030, data centers alone could account for 3–13% of global electricity use, a stark increase from the 1% recorded in 2010, propelled by escalating demands and emerging trends like large-scale AI workloads . The software industry is responsible for about 3% of global carbon emissions , which is very close to that associated with the aviation industry , and it could deteriorate if left unaddressed. Researchers have estimated that training a single machine learning algorithm for natural language processing may emit as much CO2e (carbon dioxide equivalent) as a small town with 120 homes would emit in a year . Another study reported that AI workloads in data centers made up 15% of Google’s total electricity consumption, which was 18

Any suggestions are welcome.  The Case for Green Computing and Sustainability Assessing ICT Global Emissions Footprint: Trends to 2040  & R ecommendations The Sky is Not the Limit: Untapped Opportunities for Green Computing Sustainable Computing – Without the Hot Air Green Computing Approaches - A Survey Green Data Centers Metrics for Sustainability in Data Centers The Odd One Out: Energy is not like Other Metrics A Systematic Review on Effective Energy Utilization Management Strategies in Cloud Data Centers Enabling Sustainable Clouds: The Case for Virtualizing the Energy System Treehouse: A Case For Carbon-Aware Datacenter Software Energy-Efficient Hybrid Framework for Green Cloud Computing Green Networking Greener, Energy-Efficient and

Minimizing the Energy Footprint of Global Data Movement with GreenDataFlow

It is estimated that the number of devices connected to the Internet will be four times as high as the world population in 2022, and the global IP traffic will reach 4.8 zettabytes per year. The increased number of users and data rates do not only require increased network bandwidth and achievable data transfer throughput but also result in an increased energy footprint. The annual electricity consumed by the global data movement is estimated to be more than 200 terawatt-hours at the current rate, costing more than 40 billion US dollars per year. According to the same statistics, the share of the US in this global data movement and in its energy footprint is approximately 20%. This fact has resulted in a considerable amount of work focusing on power management and energy efficiency in hardware and software systems and more recently on power-aware networking. The majority of the existing work on power-aware networking focuses on reducing the power consumption on networking devices (i

OneDataShare -- Fast, Scalable, and Flexible Data Sharing Made Easy

With the emergence of complex scientific applications, social media, video over IP, and more recently the trend for Internet of Things (IoT), the global data movement requirements have already exceeded the Exabyte scale. Large scientific experiments, such as environmental and coastal hazard prediction, climate modeling, genome mapping, and high-energy physics simulations generate data volumes reaching several Petabytes per year. Data collected from remote sensors and satellites, dynamic data-driven applications, social networks, digital libraries and preservations are also producing extremely large datasets for real-time or online processing.   This so called “data deluge” in the scientific applications necessitates collaboration and sharing among the national and international education and research institutions, which results in frequent large-scale data movement over wide-area networks. We see a similar trend in the commercial applications as well. According to a study by
