Low carbon and sustainable computing

The Low Carbon and Sustainable Computing (LOCOS) Theme groups the research in the School related to the sustainability of computing. The main focus is on reduction of emissions from computing. However, research in computing science can help in many other ways with reducing of greenhouse gas emissions and mitigation of the effects of climate change.

By 2040 emissions from computing alone will more than to half the emissions level acceptable to keep global warming below 1.5°C. This growth in computing emissions is unsustainable. The emissions from production of computing devices far exceed the emissions from operating them, so even if devices are more energy efficient producing more of them will make the emissions problem worse. Therefore we must extend the useful life of our computing devices.


The vision for Low Carbon and Sustainable Computing Theme is simple but ambitious:

  • Imagine we can extend the useful life of our devices and even increase their capabilities without any increase in energy consumption, purely through advances in Computing Science: better algorithms, better software design, better programming languages and compilers etc.
  • Meanwhile, we will develop the science and technologies for the next generation of devices, designed for energy efficiency as well as long life through pervasive hardware-software co-design.
  • Every subsequent cycle will last longer, leading to computing resources that last virtually forever and use very little energy.

Use-of-System approaches for Electricity Footprinting of Digital Media (17 November, 2022)

Speaker: Daniel Schien

Abstract

Electricity footprints are the basis to estimate the carbon emissions from use of electricity. The current metrics suggested by carbon footprinting standards such as the Greenhouse Gas Protocol ICT sector guidance have shortcomings that undermine their effectiveness to support decision making with the goal to decarbonise the sector. In this talk I will be discussing these some of these shortcomings and present an idea how to move forward.

Research interests

Most of my research aims at improving our understanding of the environmental impact from information and communication technologies (ICT) and the reduction of such impact.

My most significant research contributions, so far, have been in the area of the quantifying the direct impact of ICT. I have a deep understanding of the principles that affect energy consumption in Internet-based services. Based on this, my research has pioneered new methods and tools to assess the carbon footprint of digital media which have been applied by major international media companies. I am currently leading the technical development of the DIMPACT tool (http://www.dimpact.org).

A growing area of my research focusses on the complex system of interactions between use of ICT services, use of infrastructure and design of ICT services, and in response I apply multidisciplinary methods from software engineering, human computer interaction and environmental science.

Ecovisor: A Virtual Energy System for Carbon-Efficient Applications (03 November, 2022)

Speaker: Noman Bashir

Talk Abstract: Cloud platforms' rapid growth is raising significant concerns about their carbon emissions. To reduce emissions, future cloud platforms will need to increase their reliance on renewable energy sources, such as solar and wind, which have zero emissions but are highly unreliable. Unfortunately, today's energy systems effectively mask this unreliability in hardware, which prevents  applications from optimizing their carbon-efficiency, or work done per kilogram of carbon emitted.  To address this problem, we designed an ``ecovisor,'' which virtualizes the energy system and exposes software-defined control of it to applications.  An ecovisor enables each application to handle clean energy's unreliability in software based on its own specific requirements.  We implemented a small-scale ecovisor prototype that virtualizes a physical energy system to enable software-based application-level i) visibility into variable grid carbon-intensity and renewable generation and ii) control of server power usage and battery charging/discharging.  We evaluated the ecovisor approach by showing how multiple applications can concurrently exercise their virtual energy system in different ways to better optimize carbon-efficiency based on their specific requirements compared to a general system-wide policy.

Edge Computing as a Missing Link in the Post Moore Era (20 October, 2022)

Speaker: Ivona Brandic

Title: Edge Computing as a Missing Link in the Post Moore Era

Ivona Brandic, Vienna University of Technology

 

In the first part of this talk talk we discuss the concept of extreme performance HPC where the applications often include latencies below 100 ms or even below 10 ms. To facilitate low latency computation has to be placed in the vicinity of the end users by utilizing the concept of Edge Computing. We present the novel failure resilience mechanisms applied to Edge systems considering timeliness, hyper-heterogeneity and resource scarcity. We discuss our machine learning based mechanism that evaluates the failure resilience of a service deployed redundantly on the Edge infrastructures. Our approach learns the spatiotemporal dependencies between Edge server failures and combines them with the topological information to incorporate link failures by utilizing the concept of the Dynamic Bayesian Networks (DBNs). Eventually, we infer the probability that a certain set of servers fails or disconnects concurrently during service runtime. The robustness of the approach has been evaluated using the concept of code offloading. 

In the second part we discuss the potential impact of Edge Computing in the current rise of highly specialized architectures ranging from neuromorphic to quantum computing. As we experience the paradigm shift from generalized architectures of the Von Neumann era to highly specialized architectures in the Post-Moore’s law era we expect the coexistence of multiple types of architectures specialized for different types of computation. We define the two of the architectures that attracted the most interest in the research community, where we witness not only theoretical developments but also first implementations and practical use cases. Afterward, we discuss the first ideas but also challenges in the integration of identified architectures into existing HPC systems.

About the speaker Univ. Prof. Dr. Ivona Brandić
Head of the Research Group on High Performance Computing Systems


During the last years, my research agenda comprised the development of QoS methods for different generations of distributed systems like Grids, Web Services, Workflows, Clouds, Multi Clouds and Edge infrastructures. During my PhD I developed novel QoS mechanisms for scientific Grid workflows such as maxillo facial surgery simulation (eScience 2005). My visit to the University of Melbourne triggered my research on SLA guaranteeing in Clouds and later on energy efficient management of ultra-scale systems (FGCS 2009). My research style is systems based. In 2012, I devised strategies for the utilization of SLAs for delivering non-trivial QoS in Clouds (FGCS 2012). Later, I have utilized control theory for the energy efficient resource allocation in IaaS Clouds and I devised novel algorithms for the energy efficient deployment of ultra-scale applications in geographically distributed massive multi Clouds (TCC 2016a, TCC 2016b). The focus of my recent work is the utilization of probabilistic and statistical methods for energy efficient resource allocation in different near-real time systems such as Edge/Cloud systems (CCGrid 2018, TPDS 2021, SIGMETRICS 2020). Furthermore, I am currently working on the decomposition of applications for the execution on hybrid systems (e.g., classic/quantum) (eScience 2022).

 

Making IT Green: Awareness-Driven Service Design and Management (13 October, 2022)

Speaker: Monica Vitali

TITLE: Making IT Green: Awareness-Driven Service Design and Management
 
ABSTRACT: The scientific and industrial communities are well aware of the growing impact of IT and data centers on carbon emissions. This impact has been mitigated by the improvements in infrastructure efficiency and the use of renewable energies to power them. Despite efforts to reduce the carbon footprint at the infrastructure level, the energy demand for applications hosted in data center facilities is growing rapidly. It will soon not be possible to compensate for this by improving the efficiency of the infrastructure. To move forward, it is necessary to shift the focus on sustainability from a purely infrastructural perspective to an application-oriented perspective, providing best practices, methods, and tools for incremental and continuous improvement of carbon-sensitive multi-component applications in a heterogeneous fog infrastructure fog. Sustainability should be seen as a strategic variable, shifting the focus from performance-oriented application management to sustainability-conscious management. To achieve this, service-oriented application designers should be supported by increasing their awareness of the application footprint and suggesting effective actions to reduce it. In this process, the cooperation of all stakeholders is essential: the infrastructure provider, the application owner, and the end user should collaborate. 
 
BIO: Monica Vitali is an Assistant Professor at Politecnico di Milano, Italy, since June 2021 and a Visiting Researcher at Umeå University, Sweden, since January 2020. Her main interests in research are related to Information Systems and their Energy Efficiency and Quality of Service. She researches new strategies to improve the efficiency of data centers, clouds, and fog computing by applying techniques derived from the Artificial Intelligence and Machine Learning fields. She is interested in adaptation and self-adaptation to discover how a complex system can heal itself when some problems occur. More specifically she has been working on energy efficiency and sustainability of cloud and fog applications, QoS-aware deployment in edge and fog computing, Data Quality in big data environments, Ambient Assisted Living, Smart Cities, and Smart Buildings.

What do software engineers think about sustainability? (06 October, 2022)

Speaker: Tim Storer

What do software engineers think about sustainability?

 

Tiffany Babey, Catherine Happer and *Tim Storer*

 

Abstract: Over at least the last 25 years, the key consideration in the practice of software engineering has been the maintainability and readability of code.  Seminal practitioner texts such as the GoF’s Design Patterns, Fowler’s Refactoring and Martin’s Clean Code, and Hunt and Thomas’ The Pragrammatic Programmer have all emphasised the organisation of code to enhance it’s readability to make change easier.  Software sustainability has also been largely discussed in these terms, for example the (excellent!) Software Sustainability Institute’s manifesto emphasises sustainability entirely in terms of reproducibility and reusability.  However, there are early signs that both researchers and practitioners are realising that sustainability in software practice should be conceived more widely.  For example, the Karlskrona Manifesto for Sustainability Design identifies five dimensions of sustainability, spanning economic, social, individual, technical and environmental considerations.   Sustainability as an urgent priority then, can be expected to require significant change in how software engineers practice their profession, the methods and tools they use and the choices they make for the construction and operation of software systems.  However, little is known about what software engineers themselves think about the impact that sustainability considerations is having and will have on their practice.  We have begun a research project to understand these perspectives.  In this talk I will report on results of our initial survey to understand the perceptions, thinking and priorities of ~70 software engineers and the organisations they work for.

IoT Software updates over IPv6 multicast: lessons in experimentation (22 September, 2022)

Speaker: Esther Payne

Abstract

The Librecast Project believes that multicast is an underutilized and
misunderstood network technology.

We want to make the argument that in today's interconnected world
multicast is vital to scale up and meet the requirements of a modern
Internet. Multicast is better for the environment than unicast. But
how do we demonstrate this use case beyond the normal use case for
streaming audio and video locally in real time? We believe Multicast is
even better suited to non-streaming applications than to it's
traditional utilisation.

To prove our claims we needed to create some experiments to compare
Unicast and Multicast. Librecast decided to simulate one particular
usecase: Software Updates.

Utilising a POC IoT software updater was only the start.

We aimed to demonstrate just how differently multicast designed systems
are compared to unicast. Unicast systems depend on spreading of the
load to deliver updates. The load will spike, so with unicast load
needs to be spread. Multicast does the opposite of this. For one
thing, because multicast is pull not push. At scale the advantages of
multicast really shine through. The load on a multicast node does not
increase, no matter how many clients connect to it.


Using Fed4fires federated Testbeds, Librecast aimed to simulate this and
design a series of experiments to show the differences in simulating
unicast software updates and multicast software updates.

There are stark differences in how these two types of networking work.
Which has real world implications for reducing the Software Carbon
Footprint of our existing internet and beyond as more systems get
connected. Designing our networks to use multicast could mean less
servers need to be available. Which in the current energy crisis and
beyond could lead to financial and environmental benefits.

LC&SC Seminar: Envirofy: A Techno-Fix for Sustainable Online Grocery Shopping (05 May, 2022)

Speaker: Dr Gözel Shakeri

Two thirds of global greenhouse gas (GHG) emissions of Western countries are attributable to consumption and commerce, however a behavioural shift could reduce this by 49%. Many people intend to make sustainable choices, but fail to do so at the point-of-purchase. Educating consumers on the environmental impact of their choices during their shop may be a powerful approach to tackling climate change. In this talk I will present Envirofy, an eco-friendly e-commerce grocery tool for real shoppers. I will share how we use the Behaviour Change Wheel (BCW) and multidisciplinary evidence to maximise the likely effectiveness of Envirofy. I will discuss how the Human-Computer Interaction community can help to develop and evaluate real-time tools to close intention-behaviour gaps and ultimately reduce GHG emissions. Finally, I conclude with a short opinion piece on Envirofy's role (a techno-fix) in the politicised debate around climate change.

Dr Gözel Shakeri is a post-doctoral research associate in Human-Computer Interaction at the Carl Ossietzky University, Oldenburg. Her research interests focus on Sustainable Human-Computer Interaction (HCI), using behaviour change intervention science to create interfaces that support online shoppers in purchasing sustainable products

LC&SC Seminar: The Climate Impacts of ICT (21 April, 2022)

Speaker: Dr Kelly Widdicks

The Climate Impacts of ICT

Information Communication Technology (ICT, including devices, networks and data centres) has environmental impacts associated with each stage of its lifecycle, with current studies estimating that the world’s ICT forms 1.8-2.8% of global greenhouse gas emissions. However, this share is likely underestimated as the full supply chain impacts of ICT are not considered, meaning ICT’s true share of global greenhouse gas emissions actually  forms between 2.1-3.9%. Current studies’ estimates vary even further for the future environmental impact of ICT as experts take varying underlying assumptions that are not always made explicit. In this talk, Dr Kelly Widdicks will discuss the research she conducted with colleagues at Lancaster University and Small World Consulting (published in Patterns) on the climate impact of ICT. Specifically, she will reveal why current estimates vary and detail the underlying assumptions that impact estimates of ICT’s future environmental impacts. She will also discuss the threats that will likely increase ICT’s environmental impacts and the efforts required to align the ICT sector with global carbon targets.

 

Dr Kelly Widdicks is a Lecturer in Computer Science in the School of Computing and Communications at Lancaster University, researching the sustainable and responsible design of digital technology. She utilises quantitative and qualitative methods in the field of Human-Computer Interaction to explore how people’s use or innovation of digital technology affects its environmental impacts. She is currently a co-investigator for the EPSRC PARIS-DE project, exploring design principles for the responsible innovation of digital technology in line with Paris Agreement targets. Alongside this, she also researches how Computer Science as a discipline could be made more inclusive for women and underrepresented groups.
