Accelerating Datacenter Services with Reconfigurable Logic

by Aaron Smith, Microsoft Research

Datacenter workloads demand high computational capabilities, flexibility, power efficiency, and low cost. It is challenging to improve all of these factors simultaneously. To advance datacenter capabilities beyond what commodity server designs can provide, we have designed and built a composable, reconfigurable fabric at Microsoft to accelerate portions of large-scale software services. In this talk I will describe a medium-scale deployment of this fabric on a bed of 1,632 servers, and discuss its efficacy in accelerating the Bing web search engine along with future plans to improve the programmability of the fabric.

Bio: Aaron Smith is a member of the Computer Architecture Group at Microsoft Research. He is broadly interested in optimizing compilers, computer architecture and reconfigurable computing. Over the past 15 years he has led multiple industrial and research compiler projects at Metrowerks/Freescale Semiconductor, The University of Texas at Austin and Microsoft. He received his PhD in Computer Science from UT-Austin in 2009 and is currently serving as co-General Chair of CGO 2015.

Design Frontiers in Parallel Languages: The Role of Determinism

Constraints can be a source of inspiration; their role in creative art forms is well-recognized, with poetry as the quintessential example.  We argue that the requirement of determinism can play the same role in the design of parallel programming languages. This talk describes a series of design explorations that begin with determinism as the constraint, introduce the concept of monotonically-changing concurrent data structures (LVars), and end in some interesting places—flirting with the boundaries to yield quasideterminism, and revealing synergies between parallel effects, such as cancelation and memoization, when used in a deterministic context.

Our goal is for guaranteed-deterministic parallel programming to be practical and efficient for a wide range of applications. One challenge is simply to integrate the known forms of deterministic-by-construction parallelism, which we overview in this talk: Kahn process networks, pure data-parallelism, single assignment languages, functional programming, and type-effect systems that enforce limited access to state by threads. My group, together with many others around the world, are developing libraries such as LVish and Accelerate that add these capabilities to the programming language Haskell. It is early days yet, but already possible to build programs that mix concurrent, lock-free data structures, blocking data-flow, callbacks, and GPU-based data-parallelism, without ever compromising determinism or referential transparency.

Computational Social Choice: an Overview by Edith Elkind, University of Oxford

ABSTRACT
In this talk, we will provide a self-contained introduction to the field of computational social choice – an emerging research area that applies tools and techniques of computer science (most notably, algorithms, complexity and artificial intelligence) to problems that arise in voting theory, fair division, and other subfields of social choice theory. We will give a high-level overview of this research area, and mention some open problems that may be of interest to mathematicians and computer scientists.

Doing Research in the Wild – Paul Marshall, UCL

Abstract: There has been
significant growth in interest in ‘research in the wild’ as an approach to
developing and understanding novel technologies in real world contexts.
However, the concept remains underdeveloped and it is unclear how it differs
from previous technology deployments and in situ studies. In this talk, I will
attempt an initial characterisation of research in the wild. I will discuss
some of the benefits of studying novel technologies in situ as well as some of
the challenges inherent in encouraging and studying sustained use.

Bio: Paul Marshall is a lecturer in interaction design in the UCL
Interaction Centre. His research interests focus on understanding how
ubiquitous computing technologies are used in everyday contexts such as the
home, in education or in public spaces. Prior to joining UCL he worked as a
post doc at the University of Warwick (2010-11) researching participatory
design approaches in healthcare and at the Open University (2006-10) where he
ran ethnographic and laboratory studies of shareable interfaces and sensory
extension devices. He completed a PhD project on learning with tangible
interfaces as part of the Equator project at the University of Sussex, and
prior to that a BSc (Hons) in psychology at the University of Edinburgh.

Cybersecurity for Critical Infrastructure

Cybersecurity for Critical Infrastructure, or ‘how to break into a nuclear power station for fun & profit’

Dr Richard Gold, Cisco Systems, UK

Cyber Security for Critical Infrastructures such as the power grid, oil & gas pipelines and dams has become a hot topic since the Stuxnet malware attack against the nuclear enrichment centrifuges in Iran. However, due to intrinsic issues with the field of Critical Infrastructure (a.k.a., ICS or SCADA), it is difficult to deploy standard IT security solutions “as is” to these systems. In this talk I discuss the problems associated with deploying effective security processes in Critical Infrastructures, the various types of security holes which these system contain and a step-by-step approach to exploiting a Critical Infrastructure installation. Thinking from the attacker’s perspective allows us to get an insight into how these systems are vulnerable and how a potential attacker might exploit them.

Evaluation of Network Resilience and Survivability: Analysis, Simulation, Tools, and Experimentation by James P. G. Sterbenz, ITTC, University of Kansas

As the Internet becomes increasingly important to all aspects of society, the consequences of disruption are increasingly severe. Thus it is critical to increase the resilience and survivability of the future networks in general, and the Internet in particular. We define resilience as the ability of the network to provide desired service even when the network is challenged by attacks, large-scale disasters, and other failures. Resilience subsumes the disciplines of survivability, fault-tolerance, disruption-tolerance, traffic-tolerance, dependability, performability, and security. After an introduction to the disciplines and challenges to network resilience, this presentation will discuss analytical, simulation, and experimental emulation techniques for understanding, evaluating, and improving the resilience of the Future Internet. This includes a multilevel state-space based approach that plots network service delivery against operational state that is the basis for both mathematical- and simulation-based analysis, and graph-theoretic complex-system approaches that embed fundamental properties such as redundancy and diversity into all aspects of network structure, mechanism, and protocols. A set of tools to help in this analysis has been developed: KU-LoCGen (Location and Cost-Constrained Topology Generation), KU-TopView (Topology Viewer), and KU-CSM (Challenge Simulation Module). Plans to experimentally evaluate resilience include using the international programmable testbed GpENI: Great Plains Environment for Network Innovation. A new composable, cross-layered resilient transport protocol (ResTP) and geodiverse multipath routing protocol (GeoDivRP) are being developed.

Evolution of our existing institutional research information infrastructure : a facilitator for Open Science?

Anna Clements, Head of Research Data and Information Services, University of St Andrews.

Open Science’ seems to be one of the hottest topics around with organisations and funders from the G8 downwards stressing the importance of open data in driving everything from global innovation through to more accountable governance; not to mention the more direct possibility that non-compliance could result in research grant income drying up.
Here at St Andrews we have had an institutional research information system (CRIS) since 2006 which has evolved in tandem with the rapidly changing research policies and slower cultural shifts towards more and more open access to research outputs, outcomes and impact. But, we now face, perhaps, the biggest challenge so far in determining the extent to which Institutional infrastructure and services can support this transition to an ‘open by default’ culture. I will argue that this challenge cannot be met without researchers engaging with the debate and driving the agenda forward with the support services here at St Andrews – there is a joint responsibility very clearly articulated in the EPSRC policy framework on research data. So there will be some suggestions on what we could do by building on our existing infrastructure, including examples of best practice from elsewhere, but also an invitation to the audience for suggestions on how to respond to this incessant and increasing clamour for access to research outputs and, in particular, research data.
