April 13th, seminar by Nicolai Marquardt: Towards Ad-hoc Collaboration Spaces with Cross-Device Interaction Techniques

Speaker: Nicolai Marquardt, University College London
Date/Time: 1-2pm April 13, 2015
Location: CS1.33a, University of St Andrews

Abstract:
Despite the ongoing proliferation of devices and form-factors such as tablets and electronic whiteboards, technology often hinders (rather than helps) informal small-group interactions. Whereas natural human conversation is fluid and dynamic, discussions that rely on digital content—slides, documents, clippings—often remain hindered due to the awkwardness of manipulating, sharing, and displaying information on and across multiple devices. Addressing these shortcomings, in this talk I present our research towards fluid, ad-hoc, minimally disruptive techniques for co-located collaboration by leveraging the proxemics of people as well as the proxemics of devices. In particular, I will demonstrate a number of cross-device interaction techniques—situated within the research theme of proxemic interactions—that support nuanced gradations of sharing. I will also introduce different novel hybrid sensing approaches enabling these interaction techniques and discuss future research directions.

New EPSRC project C3: Scalable & Verified Shared Memory

C3: Scalable & Verified Shared Memory via Consistency-directed Cache Coherence

Dr Susmit Sarkar

Dr Susmit Sarkar

Susmit Sarkar with colleagues in the University of Edinburgh and Intel as project partners, have been successful in their application to the EPSRC for their project C3: Scalable & Verified Shared Memory via Consistency-directed Cache Coherence. This 3 year project starts in July 2015 and aims to realise scalable and verified shared memory.

Shared-memory multi-core processors are ubiquitous, but programming them remains challenging. The programming model exposed by such multi-core processors depends crucially on a “memory consistency model” (MCM), a contract between the hardware and the programmer, which essentially specifies what value a read can return. On the hardware side, one key mechanism to implement the memory consistency model is the “cache-coherence protocol” (CCP), which essentially communicates memory operations between processors. However, the connection between the CCP and the MCM remains unclear. This is especially true for modern CCPs and MCMs, in which CCP design has been divorced from the requirements of the MCM. Susmit and his colleagues argue that this has negatively impacted the scalability and the verifiability of CCPs.

On the scalability front, there are serious question marks about sustaining cache coherence as the number of cores continue to scale. On the verification front, the application of existing verification techniques, which do not verify the CCP against the MCM, are arguably broken.

The C3 proposal, proposes a family of CCPs that are “aware” of, and verified against the MCM. Their approach is motivated by the fact that both hardware and programming languages are converging to various relaxed MCMs for performance oriented reasons. The team use such relaxed MCMs as inspiration to research CCPs that can take advantage of them.

Specifically, they will research “lazy” CCPs where memory operations are batched, and the cost of communicating a memory operation can be amortised. They will also, for the first time, formally verify the relationship between the hardware CCPs and the programmer-oriented MCM they provide. They will investigate rigorously the gains to be had from such lazy CCPs. The team will do this by creating a multi-core silicon prototype of our proposed CCP, leveraging our experience in the design of industrial-strength micro-architectures and their implementations.

Mario Kart Around the World

The School recently hosted “Mario Kart Around the World” for students from Newport Primary.

All versions of Mario Kart with the exception of arcade versions were available for the youngsters to play. Our visitors had access to a range of consoles and games ranging from Vectrex to Leap Motion and a great opportunity to see modern equipment and how it looked in the “olden days“.

Torchlit Procession

The Torchlit Procession and Rectorial Drag are historic university traditions, in February the soon-to-be-installed Rector Catherine Stihler addressed all students in St Mary’s Quad. The Torchlit Procession later in the evening left from Sallies Lawn where students collected and lit their torches. The walk continued down to the pier offering some fabulous photographic opportunities.

March 10th, seminar by Nick Taylor: Sustaining Civic Engagement in Communities

Speaker: Nick Taylor, University of Dundee
Date/Time: 2-3pm March 10, 2015
Location: CS1.33a, University of St Andrews

Abstract:
Engagement with local issues is typically very low, despite digital technologies opening up more channels for citizens to access information and get involved than ever before. This talk will present research around the use of simple physical interfaces in public spaces to lower barriers to participation and engage a wider audience in local issues. It will also explore the potential for moving beyond top-down interventions to support sustainable grassroots innovation, in which citizens can develop their own solutions to local issues.

Bio:
Nick Taylor is a Lecturer and Dundee Fellow in the Duncan of Jordanstone College of Art and Design at the University of Dundee. His research interests involve the use of novel technologies in social contexts, particularly in communities and public spaces. This has involved the exploration of technologies to support civic engagement in local democracy, public displays supporting community awareness and heritage, as well as methods of engaging communities in design.

This seminar is part of our ongoing series from researchers in HCI. See here for our current schedule.

CNC Router Test PCB Made

The first real test of the CNC Router milling a printed circuit board took place this week and the results so far are very encouraging.

Scienceduino PCB

The PCB design is part of a suite of hardware required for a research project. This involves the development of a Science grade Arduino we have called Scienceduino , it will be used to log analogue data with a high degree of accuracy and traceability , in terms of readings and time logging. The picture of the complete PCB shows the complexity and general layout of the components , these will be mostly surface mount. Surface mount technology is being used to help reduce the overall size of the system and to allow automated manufacture.

PCB Microscope Image

The microscope webcam picture shows a circular pad which is 1.0mm in diameter , track width of 0.35mm and track spacing of 0.35mm. The copper flakes in the gaps on the PCB will be cleaned away with water and detergent. So all in all this is good news for the School’s ability to manufacture PCB’s for various research projects.

School Seminars: Building the News Search Engine – Bloomberg

Building the news search engine, by Ramkumar Aiyengar, Bloomberg
Abstract:
This talk provides an insight into the challenges involved in providing near real-time news search to Bloomberg customers. Our News team is in the process of migrating to using Solr/Lucene as its search and alerting backend. This talk starts with a picture of what’s involved in building such a backend, then delves into what makes up a search engine, and then discusses the challenges of scaling up for low-latency and high-load.
Bio:
Ramkumar leads the News Search backend team at the Bloomberg R&D office in London. He joined Bloomberg from his university in India and has been with the News R&D team for 7 years now. For the last couple of years, his team has focussed on rewriting almost the entire search/alert backend, used by almost every Bloomberg user to get near-real time access to news with sub-second latencies. A geek at heart, he considers himself a Linux evangelist, an open source enthusiast, and one of those weird creatures who believes that Emacs is an operating system and had once got his music player and playlists to be controlled through a library written in Lisp.
