New Year's Wishes from the Chair

By Niklas Carlsson, Linköping University, Sweden

Happy New Year! I would like to start this newsletter by wishing all members and non-members a Happy New Year, but also by making a shout for contributions to help make our world a better and more sustainable place to live.

We are living in a highly dynamic and quickly changing world. Some things are clearly changing to the better, whereas other aspects provide us with significant challenges. There are constantly countless reminders of many aspects that yet have to be improved for our society, economy, and environment to become sustainable. This includes (but is definitely not limited to) the ongoing migration crisis, wars, environmental disasters, global warming, and many other ongoing humanitarian and environmental crises. We only have one planet, and we must take care of it together! Referring to the goals of our STC, for example, our community can play an important role in (i) facilitating computing for sustainability, as well as (ii) promoting the design and implementation of sustainable computing. Such efforts will help towards making both ICT and non-ICT processes become more sustainable. Addressing both these goals may be particularly important as we are moving into the age of big data and everything may become connected through the Internet of Things, for example. With increasing information and data at our hands, computing and analytics is expected to play an important role in helping us find new and better solutions to both new and existing problems. However, it is also important to remember that all computing must be done efficiently and with infrastructure that does not add to the problems. As we go into 2016, I hope that we as a community can help tackle all these important challenges and I look forward to reading about all of your contributions.

PS. If you are interested in contributing to the STC or to the newsletter, please contact myself (Niklas Carlsson) or our excellent newsletter editor Cristina Rottondi. (We are looking for both technical and non-technical contributions accessible to everybody.)

Message from the editor

We inaugurate the new year with a very interesting collection of contributions: first of all, we congratulate Dr. Albert Zomaya on his new appointment as Editor in Chief of the IEEE Transactions on Sustainable Computing, which was launched a few weeks ago. Dr. Christopher Stewart discusses aims and scopes of the Green Climate Fund finalized during the 2015 Paris Climate talks. Dr. Lei Rao interviews Prof. James Landay from Stanford University, whose research primarily focuses on specializing in human-computer interaction. We conclude with a list of the most relevant upcoming scientific conferences and workshops related to sustainable computing and green communications, drawn up by Prof. Samee U. Khan.

The launch of the new IEEE Transactions of Sustainable Computing

We are excited to announce the launch of the new IEEE Transactions on Sustainable Computing (T-SUSC)! It is a peer-reviewed journal devoted to publishing high-quality papers that explore the different aspects of sustainable computing, over a wide range of problem domains and technologies from software and hardware designs to applications. Sustainability includes energy efficiency, natural resources preservation, and use of multiple energy sources as needed in computing devices and infrastructure.

Solutions for these problems call upon a wide range of algorithmic and computational frameworks, such as optimization, machine learning, decision support systems, meta-heuristics, and game-theory. Contributions to T-SUSC must address sustainability problems in computing and information processing environments and technologies, and at different levels of the computational process.

The T-SUSC Editor-in-chief for the 2016-2018 triennium is our Communication Chair Albert Zomaya: congratulations to him on this prestigious appointment and the warmest wishes from the STC community for a great success!! Dr. Zomaya is currently the Chair Professor of High Performance Computing & Networking and Director of the Centre for Distributed and High Performance Computing in the School of Information Technologies, The University of Sydney. Prior to his current appointment he was a Full Professor in the Electrical and Electronic Engineering Department at the University of Western Australia, where he also led the Parallel Computing Research Laboratory during the period 1990–2002. He served as Associate–, Deputy–, and Acting–Head in the same department, held numerous visiting positions and has extensive industry involvement.

Dr. Zomaya published more than 500 scientific papers and articles and is author, co-author or editor of more than 20 books. He served as the Editor in Chief of the IEEE Transactions on Computers (2011-2014). Currently, Dr. Zomaya serves as associate editor for 22 leading journals, such as, the ACM Computing Surveys, IEEE Transactions on Cloud Computing, IEEE Transactions on Computational Social Systems, and Journal of Parallel and Distributed Computing. Dr. Zomaya is the Founding Editor of the Wiley Book Series on Parallel and Distributed Computing.

The Green Climate Fund Could Reshape the Economics of Sustainable Computing (PDF version)

Christopher Stewart, The Ohio State University

Sustainable computing has come so far. When I first presented  my ideas on renewable-powered data centers in 2007,
my peers literally laughed out loud [14]. Now, several communities  have explored a wide range of sustainable computing
issues. With projects like the NetZero Data Center [10], Parasol  [6] and iSwitch [9], researchers have laid the intellectual
ground work to manage the carbon emissions caused by a data center. Research on the intellectual basis for carbon-
aware resource management has also blossomed [3], [11], [13], [2], [8], [15], [7], [5], [12].To be sure, this list is not nearly
exhaustive, but it does highlight the diversity of top venues that look for papers on sustainable computing.

Even though sustainable computing is gaining steam intellectually.  Critics on the business side of computer science  research remain unconvinced. I am sure many of you have at some point received a critique like the following:

I  cannot assign merit to the work beyond the warm feeling of doing something for mother earth.”  – Anonymous reviewer

The critics of sustainable computing focus on three arguments. First, they claim that any expense put to lowering
carbon emissions does not increase profit and therefore is purely an intellectual matter. Second, they feel there is no
need for computer science reseachers to become experts on the subject, since presumably their are other researchers in the world that understand environment issues. Finally, and this is a big one, many reviewers will claim that energy prices are a
small part of overall data center expenses. As a result, even efforts at energy efficiency can be viewed skeptically.

I believe all of these criticisms can be silenced by the Green Climate Fund [4] (GCF), a banking platform finalized during
the 2015 Paris Climate talks. The GCF will manage roughly $100B per year, providing loans and grants for technologies
in developing countries that reduce carbon emissions.

Fig. 1: The costs of hosting 10 computing racks, estimated by The Cloud Calculator. 

Fig. 2: Cost savings as a function of interest rate. 

Figure 1 plots costs to (1) build a 10-rack data center and (2)  lease co-location space for 10 racks [1]. It highlights the role of  interest. 7% interest over a 3-year evaluation period constitutes about 20% of total costs. The GCF will have the ability to alter
its interest rates, providing considerable savings to sustainable data centers. Figure 2 plots the cost savings for the data center
owner as a function of the GCF interest rate reduction. We assume (as critics wrongly claim) that sustainable data centers increase electricity costs by 30% (expensive) or 10% (cheap). A reduction of 1.5 basis points (i.e., an effective rate of 5.5%)
is enough to justify the 30% increase in energy costs. Data center owners could save hundreds of thousands of dollars.

I hope the GCF considers data centers as it looks to influence the reduction of greenhouse gasses. We all know the IT sector contributes significantly to global emissions (well over 2% [11]). Reconsider Figure 1, the cost of building a
data center from the ground up (excluding servers) is just over $1M. An investment of 2% by the GCF would cover nearly
2,000 data centers annually— that could spark and sustain a boom in sustainable data centers.

Favorite experiences among all the roles including researcher, lab director, professor, as well as entrepreneur in both academia and industry

In academia, the most enjoyable part is to work with undergraduate and graduate students in different ways. It is fun to work on things that will play out in the future, i.e. ten to fifteen years ahead of existing product solutions. Teaching students is definitely an important part of this process. With respect to industry, I worked as a CTO of a startup, a researcher for Microsoft Research (MSR) and a lab director for Intel. When working for large companies like MSR and Intel, the goal was to leverage more resources to build bigger things. For big companies, strategy and communications are always important, while for startups, developing and building out ideas to get things out fast is always critical.

Opinions on how Human Computer Interaction (HCI) is going to impact human behavior hence impacting sustainable computing

For sustainable computing, there are three goals: first, to make better policy decisions & city planning (e.g. to build a city and transportation infrastructure to be more sustainable); second, to develop computing & sensing technologies that enable more efficient systems and to measure human behavior; and third, to build HCI interfaces that use measured behavior to provide feedback and thus shape more sustainable human behavior. For activity sensing, we do not only need faster and cheaper devices, but also want those to be of smaller size and with more user-friendly interfaces.

Thoughts about emerging sustainable computing systems

Aging has been a critical problem for both citizens in the USA and in China. Societies and economies lack sufficient labor resources to care for seniors as they age. One project we worked on at Intel Seattle Lab was to leverage sensing, & machine learning methodologies as well as user interface designs to build systems for helping seniors age in place (i.e., in their own homes). This type of systems allows people to take care of themselves with support from their families. These same technologies can also be used for other health issues, including obesity, by helping people to achieve their goals in, for example, eating and exercise.

Takeaways for young students/researchers/entrepreneurs

To students and young researchers: try far out risky things and get out of your comfort zone. To researchers: look at the diversity of users in the world and pay attention to the concerns of the global population. Do not only solve problems for rich people.
