Update: Open Global Systems Science Conference – June 10-12, Brussels


Organized by the Global Climate Forum on behalf of the steering committee of the EU project GSDP in cooperation with the EU projects EUNOIA, FOC, INSITE, MULTIPLEX, NESS, and the G3M project, funded by the German BMU.

The study of problems as diverse as global climate change and global financial crises is currently converging towards a new kind of research – Global Systems Science. GSS is emerging hand in hand with the substantial advances in Information and Communication Technologies (ICT). The use of computer models, digitized data, and global virtual networks are vital for GSS, in the same fashion that GSS can become a trigger for truly disruptive developments in policy-oriented and socially useful ICT.

The purpose of this conference is to discuss a possible research program for Global Systems Science and to further build up the community of practitioners from science, policy and civic society working on the pressing global challenges of our times.

This conference is conceived as a two day-event with a third day for interested sub-groups and workshops. It is embedded in an on-going conversation taking place in many settings, including The present program version may evolve further at the conference as a result of this conversation.

The conference is structured by plenary and break-out group sessions. It will develop from a format focused on plenary sessions on the first day towards break-out group targeted workshops on the third day. The second day will follow a hybrid format of plenary and break-out group sessions.

All participants are asked to actively contribute and participate in the different plenaries as well as the break-out group discussions. This second conference has attracted a significant number of remarkable researchers and practitioners from all over the world and therefore the opportunities for further networking and learning are unique. The event has been organized in a style that facilitates an open dialogue among all participants.

This event is part of a series of workshops carried out by the research network Global Systems Dynamics and Policy and follows the First Open Global Systems Science Conference carried out in November 2012. It also constitutes part of a series of open GSS conferences which shall continue in the years to come.

We are working on elaborating an ambitious research agenda driven by policy needs and developing and using ICT to meet policy and societal challenges in close consultation with policy makers and citizens.

CFP: Functional High-Performance Computing (FHPC 2013)

I just want to “advertise” the Functional High-Performance Computing workshop which this year has “Large-Scale Simulation” as their theme which I think fits very well with GSS. Half of the organizers (Fritz Henglein and Jost Berthold) are at the HIPERFIT research center in Denmark (HIPERFIT: research in tailor-made expressive programming languages, frameworks, tools and technologies for financial modeling, and effective use of modern parallel hardware without compromising correctness, transparency or portability.)

Kind regards,

Patrik Jansson



The FHPC workshop aims at bringing together researchers exploring uses
of functional (or more generally, declarative or high-level) programming
technology in application domains where large-scale computations arise
naturally and high performance is essential. Such computations would
typically — but not necessarily — involve execution on highly parallel
systems ranging from multi-core multi-processor systems to graphics
accelerators (GPGPUs), reconfigurable hardware (FPGAs), large-scale
compute clusters or any combination thereof. It is becoming apparent
that radically new and well founded methodologies for programming such
systems are required to address their inherent complexity and to
reconcile execution performance with programming productivity.


GSS Languages workshop

As part of the GSS conference in June, I’m chairing a workshop on “Formal Languages and Integrated Problem Solving procedures in GSS”. It is one of five parallel workshops on “Knowledge Technologies for GSS” on Tuesday 2013-06-11: 11.00 – 13.00. I’ve created a wiki-page with some more details about the workshop:

So far it contains the text below, but it will be completed within a few days.

Global Systems Science (GSS) is about developing systems, theories, languages and tools for computer-aided policy making with potentially global implications. The focus of this workshop is the interaction between core computer science, software engineering and GSS. Topics covered include

  • Languages for policy formulation and enforcement
  • Software as a key to productivity and innovation in industry and academia
  • Domain Specific Languages for Financial IT

We will also touch upon

  • Dependable modelling
  • Verification and Validation of Simulation Models


Speaker: Piero Bonatti

Title: Languages for policy formulation and enforcement

Abstract: Policies govern and constrain a system’s behavior, and as such specify mappings from complex situation descriptions to decisions (or at least sets of options to support human decision making). The perfect languages for expressing such mappings should enjoy a number of features, including: clarity and conciseness, explainability, formal verifiability, and the ability of adapting to an enormous number of possible event combinations. The same requirements arise in the restricted domain of security policies. In this talk, the experience gathered in this field will be reported with the purpose of identifying the most effective languages for policy formulation.

ASU workshop Feb2013 -Territorial vs functional patterns

Global Systems Science: Territorial versus Functional Patterns

Arizona State University, February 25/26

Dear colleagues,

Here it goes some presentations and pictures from our very exciting workshop here in Arizona, more comments, reactions and presentation will follow soon.

There was a lot of good discussions and I will not try to summarise that, but for your interest you may want to have a look at Stefano presentation on a posible tool which could act as at early warning system for global financial systemic vulnerability as very good example of future GSS tools and methods.

All the best,

Workshop on Territories and Functions started

We are starting to work on this right now, and as usual will use the blog as a platform for discussion. Some background for the workshop is to be found in the post “Starting a GSS reading list”, and there in particular the paper “Algorithms, Games and the Internet” by Papadimitriou. The internet – which includes the users! – is a paradigmatic example of a global system, and studying it by means of iterated games in large populations with randomized matches between players – which include computers ! – turns out to be a very fruitful approach. Remarkably, the same approach makes a lot of sense when studying markets, including the marketplaces that play an essential role in the dynamics of the global urban system.

Some pointers regarding Tuesday AM discussion (posted by SB)

– Discussion about how shocks can get amplified in a network economy
Bak, P., Chen, K., Scheinkman, J., Woodford, M., 1993. Aggregate fluctuations from independent sectoral shocks: self-organized criticality in a model of production and inventory dynamics. Ricerche
Economiche 47, 3–30.

– Related to this. Is there any cascade model of how the subprime was able to trigger the financial crisis? One argument is the following: the subprime market volume was very small compared to the overall global financial assets. However, there has been a building up of instability due the fact that risk associated with all mortgages related securities had been underestimated. The default of subprime mortgages triggered a shift of beliefs in the market players regarding a much larger portion of the market.
