TUCS Distinguished Lecture Series

TUCS Distinguished Lecture on 25.10.: Axel Jantsch

Friday, October 25, 2013 at 13.15

ICT Building, Auditorium Alpha

Coffee served from 12:45

Axel Jantsch, KTH: "The Rise and Fall of System-on-Chip: Driving Concepts and Trends in the Field of Integrated Circuits Between 1990 and 2020"

Host: Juha Plosila, University of Turku

Abstract:

The defining trend in our information technology age is Moore's law: "The number of transistors that can be integrated on a single silicon die doubles every 18 months." Due to that law, System on Chip (SoC) has emerged as a concept in the late 1990s when so many transistors could be integrated on a single chip that entire computing systems could be realized, including a processing unit, memory, interconnect, peripheral devices, and few hardware accelerators. Since then, Moore's law has relentlessly continued unabated to increase on-chip capabilities and we have seen the emergence of multi-core, many-core, Networks-on-Chip, single-chip cloud computers, and many more amazingly complex, tiny devices.

How long can it continue? Where will Moore's law lead us? And what comes after?
As silicon based technology is driven to its very limits, we observe a variety of other technologies emerging and maturing. Carbon-nano tubes, micro-mechanical devices, printed and flexible circuits, and functional materials, excite engineers' imagination with their potential to applications far beyond traditional silicon devices. As Moore's law finally runs out of steam, a heterogeneous future emerges that is based on a rich variety of technologies with silicon based components as merely one of many elements, even though a central one.

This talk will describe the main trend lines and deflection points of IC technology development from the 1990s to the early 2020s, a period that witnesses an explosive growth in complexity of single chips and ends in a commonization of silicon based technology among many other technologies.

Abstract: Square matrices A,B are elementary strong shift equivalent (ESSE) over a ring R if there are (not necessarily square) matrices U,V such that A=UV and B=VU. Strong shift equivalence (SSE) over R is the transitive closure of this relation. Shift equivalence (SE) of matrices over R is a more tractable relation. For every ring, SSE over R imples SE over R.
Theorem: for every square matrix over R, the SSE-R classes within its SE-R class are in bijective correspondence with the algebraic K-theory group NK_1(R).
I'll explain the statement of the theorem, its motivation from symbolic dynamics, and state some applications to positive matrices, group extensions of shifts of finite type and the algebraic K-theory of endomorphisms.
This is joint work with Scott Schmieding.

Abstract: In 1920, Georg Pólya taught us, in the later words of Shizuo Kakutani, that "A drunken man will eventually find his way home, but a drunken bird may be lost forever."

In more mathematical terminology, simple random walk in one or two dimensions is recurrent, but in three or more dimensions transient. When, in the well-known nursery rhyme, Gretel leaves a trail of bread crumbs to help find her way home from the forest, one would expect that her "risk-reduced" random walk is also recurrent. It is interesting that we cannot prove this yet. More puzzling yet is that in the general elementary situation, we are not sure that there is a dichotomy at all - for once reinforced random walks on locally finite connected countable graphs the possibility of partial recurrence has not yet been excluded.

In this lecture I want to try to explain possible reasons for the behaviour Pólya discovered, at a leisurely pace, and the conjectures, now over twenty years old, concerning reinforced random walks on ladders. I'll finish then, time permitting, with a new dichotomy conjecture which, if true, would allow us to classify graphs into recurrent and transient ones.

TUCS Day

TUCS GP travel reports

TUCS GP travel report: SAFECOMP 2013 by Yuliya Prokhorova

Full name of the event: The 32nd International Conference on Computer Safety, Reliability and Security (SAFECOMP 2013)

Place and date: Toulouse, France, September 24-27, 2013

Type of event: conference

My article:

The scientific profile of the event: SAFECOMP is a leading conference in the areas of safety, security and reliability of critical computer applications. It provides an opportunity to share the insights and exchange experience on emerging methods, approaches and practical solutions. Major topics of the conference are fault tolerant and resilient hardware and software, architectures, error detection and error recovery mechanisms, distributed and real-time monitoring and control, model-based design and analysis, formal methods, verification and validation, safety and security cases, etc. The conference covers such application domains as railways, automotive, aerospace and avionics, medical devices and healthcare, etc.

Opinion on the best paper and its topic: In my opinion, there were two best presentations. One of them was given by Ewen Denney titled “A Formal Basis for Safety Case Patterns”. The other one was given by Sami Haddadin (one of the invited speakers) titled “It is (almost) all about human safety: a novel paradigm for robot design, control, and planning”.

Number of participants: it was around 165 registered participants during the main conference and affiliated workshops.

Social events: There were three social events during the conference. The first one was the welcome cocktail at the City Hall of Toulouse. The second event was the guided city tour which finished by wine tasting. The last event was the visit to the AIRBUS A380 final assembly chain. Afterwards, it was the banquet at the hotel d'Asezat, which is a Renaissance hotel particulier (palace) of the 16th century.

Touristic impressions: The conference took place at LAAS-CNRS. It is one of the biggest labs of French National Centre for Scientific Research (about 700 pers.). LAAS-CNRS research activities cover various topics including crucial computing, robotics, networks and communications. SAFECOMP 2013 was well organized as a one-stream conference without parallel sessions, allowing easy networking and fruitful discussions. In general, my impression of attending the conference and visiting Toulouse is highly positive. The most remarkable event was the visit of AIRBUS, which I really enjoyed.

TUCS GP travel report: SERENE 2013 by Yuliya Prokhorova

Full name of the event: 5th International Workshop on Software Engineering for Resilient Systems (SERENE 2013)

Place and date: Kiev, Ukraine, October 1-4, 2013

Type of event: autumn school and conference

My article:

The scientific profile of the event: The SERENE workshop provides a forum enabling researchers and practitioners to exchange reports on advances in all areas relevant to the development of methods for assuring resilience of software-intensive systems. In particular, it covers such topics as relations between resilience, dependability and quality attributes; modelling of resilience properties using formal and semi-formal techniques; frameworks, patterns and software architectures for resilience; cloud computing and resilient service provisioning; resilience of software-hardware co-engineering; etc. In addition, the co-allocated autumn school covers different approaches that address resilience in specific domains, namely cloud computing, self-adaptive systems, complex distributed systems, and electric power systems.

Opinion on the best paper and its topic: All the presentations at the workshop were very interesting. However, I would like to point out a couple of the best ones in my opinion. One was an invited talk given by Robin Bloomfield titled “Security Informed Safety: if It's Not Secure, It's Not Safe”. The other one was “The SafeCap Project on Railway Safety Verification and Capacity Simulation” presented by Alexander Romanovsky.

Number of participants: It was about 50 participants in total during the autumn school and the workshop itself.

Social events: There were three social events during the workshop. The first one was the welcome reception. The second one was the banquet at the restaurant with the traditional Ukrainian cuisine accompanied with live folk singing performed by a local band wearing traditional Ukrainian costumes. The last event was the guided excursion around one of the most beautiful cities in Ukraine, its capital - Kiev.

Touristic impressions: The overall program of the workshop consisted of two parts: the 2-day autumn school and the workshop itself. The school took place at the Taras Shevchenko National University of Kiev while the workshop was organized in one of the conference rooms of a hotel. This distribution allowed the participants to discover the city of Kiev and to learn about one of the biggest universities in the country. The SERENE workshop was well organized and had a rich as well as interesting social program. I really enjoyed my stay in Kiev and would recommend visiting this beautiful city to my colleagues.

TUCS GP travel report:  AMCIS 2013 by Henri Korvela

Full name of the event: o        19th Americas Conference on Information Systems

Place and date: Chicago, USA, August 15-17, 2013

Type of event: Conference

My article:

The scientific profile of the event: AMCIS is a very broad general IS research conference with a variety of tracks focusing on most IS research topics, with 28 major tracks and dozens of parallel sessions. The theme this year was “Hyperconnected world” with somewhat of a Big Data focus which was the topic of the keynote speech by Jeanne Ross.

Opinion on the best paper and its topic: Attending one of the roundtable discussions where wip papers were presented and discussed in a small group, it’s a very interesting way and is more interesting to all participants compared to poster sessions.

Number of participants: Several hundreds, 345 research papers and 173 wip papers presented.

Social events: Welcome reception on Thursday and a visit to the Impressionism, Fashion, and Modernity exhibition at The Art Institute of Chicago

Touristic impressions: Location was very central, an easy walk away from the highlights of Chicago. Museums, shopping, Navy Pier. Although the weather at the time was very hot so I was using the sightseeing tour buses to head out or return as much as possible. Main starting hub for tours was just a 10 min walk away and one of the stops right outside the conference hotel.

TUCS GP travel report: Central European Conference on Cryptology 2013 by Noora Nieminen

Full name of the event: Central European Conference on Cryptology 2013

Place and date: Telč, Czech Republic, June 25-30, 2013

Type of event: Conference

My article:

The scientific profile of the event: The aim of the conference is to bring together researchers in all aspects of cryptology.

Opinion on the best paper and its topic: I think that the most interesting paper was “An Efficient Password Based Blind Signature for Real World Applications” by Sangeetha Jose, Preetha Mathew K and Chandrasekaran Pandu Rangan because it was one of the few papers suggesting fresh, practical cryptographic applications. Moreover the presentation about the results in this paper was probably the best in this conference.

Number of participants: In total there were 44 participants.

Social events: In the first evening, we had a conference dinner at the restaurant in the Masaryk University Centre Telč (the conference place). Next day we had a visit to the Telč Chateu (http://www.zamek-telc.eu/en/)

Touristic impressions: The city of Telč is a small and beautiful city near the border of Czech Republic and Austria. It is a UNESCO World Heritage Site, and that brings tourists from all over the world. During my visit there were not too many tourists, but the day I left was clearly more vivid than the previous days. The central square and the three lakes around the city are worth seeing, in addition to the Telč Chateu.

TUCS GP travel report: EUROMICRO DSD by Sergey Ostroumov

Full name of the event: 16th EUROMICRO Conference on Digital System Design (DSD)

Place and date: Santander, Spain, September 4-6, 2013

Type of event: Conference

My article:

The scientific profile of the event: The conference was dedicated to design of various systems. In particular, the topics covered resilience of systems, application of micro technologies to diverse areas of modern life as well as modeling and verification of these systems.

Opinion on the best paper and its topic: In my opinion, there were three presentations that I would like to mention as the best ones. One of them was given by Rory O’Connor and was entitled “Inside International Standards: A Contributor’s Perspective”. Another one was delivered by Jan Madsen and was devoted to “Biochips: The Integrated Circuit of Biology”. The last one entitled “Resilient Architectures for Energy-Efficiency” was given by Antonio Gonzalez.

Number of participants: about 80 including invited speakers

Social events: There were two social events. One event took place at the City Hall of Santander hosted by the city council. The other one was at the medieval city of Santillana del Mar, where we visited Romanic collegiate church, walked ancient streets and had a fabulous dinner at the local restaurant.

Touristic impressions: The conference was very well organized. All the conference sessions took place at the same hotel. Due to a significant number of participants, the sessions were run in parallel. Nonetheless, the schedule was carefully preserved so that the participants could attend the most interesting presentations from different sessions. The city of Santander was very welcome, clean and peaceful. Unpleasant weather, which drastically changed from sunny and warm to rainy and rather cold, could not destroy a positive overall impression of the conference venue and the place.
