Event details

Network­-on-­Chip (NoC) architectures emerged as a viable solution for the design of manycore embedded systems of the next generation. While bringing new opportunities and effective energy­/performance trade­offs, they also introduce new challenges: the design of NoC based systems involves several aspects, such as the partitioning and mapping of the application to the cores, the selection of an appropriate interconnection topology, together with an appropriate routing scheme for dispatching the packets among the nodes.

The assessment of NoC based systems by performing a low-level (e.g., RTL) simulation evaluation and/or a full system simulation of the whole NoC architecture, is an extremely time-consuming approach that makes unfeasible an exhaustive exploration of all the design alternatives. High level cycle-accurate NoC simulators are widely used to quickly get an estimation of the target requirements/objectives. However, they rely on the use of synthetic traffic patterns, characterized by specific statistical properties only (e.g., packet injection rate) and do not accurately model other important aspects of real traffic scenarios.

To overcome such limitations, different benchmark suites (e.g., PARSEC, SPLASH) were proposed with the aim of including a set of applications representative of new emerging workloads for massively parallel architectures. Nevertheless, they still assume a traditional shared memory mechanism, while a message passing mechanism based on the direct exchange of data packets between nodes would probably be a more appropriate and scalable choice for next generation NoCs.

This talk describes the experience and the challenges of developing an entire design flow that, starting from a single and slow traditional shared-memory full system simulation, allows a fast and multi-objective evaluation of real applications on several different NoCs using message passing.

Professor Elena Simperl is working with the new EU Blockchain Observatory and Forum

Computer scientists from the University of Southampton will support key developments of global scale decentralised systems as part of a new EU Blockchain Observatory and Forum launched by the European Commission.

Experts from Southampton’s Department of Electronics and Computer Science (ECS) will work with European research groups and industry partners to shape blockchain technologies that will impact digital services across different sectors, e.g. in the healthcare, finance and government services.

Blockchain technologies bring about high levels of traceability and security in online transactions by storing blocks of information that are distributed across a network. The new EU Blockchain Observatory and Forum will help Europe seize new opportunities offered by this technology by building expertise and leadership in the field.

Professor Elena Simperl and Research Fellow Dr Luis-Daniel Ibáñez from ECS’s Web and Internet Science research group will publish findings from recent research and innovation activities as part of Southampton’s contribution to the international consortium.

“The EU Blockchain Observatory is one of the first projects of this kind to be supported at a European level and will provide a comprehensive, holistic overview to a field that has been advancing at great pace,” Elena explains. “The University of Southampton brings in unique expertise in studies and methods to blockchain technologies which will have profound socio-technical impacts in the near future. Our work in this project will result in white papers on specialist subjects that inform thought leadership frameworks and policies in the blockchain space. In particular, we will be promoting our recent activities around interoperable distributed ledgers and their applications in creative industries, government and science, drawing upon principles that have already made the Web so successful.”

The EU Blockchain Observatory and Forum was launched last month February and continues the European Union’s rich investment in the field. By 2020, up to €340 million in projects could be funded through the EU’s FP7 and Horizon 2020 research programmes that could draw upon blockchain technologies.

Andrus Ansip, European Commission Vice-President for the Digital Single Market, says, “Technologies like blockchain can help reduce costs while increasing trust, traceability and security. They have huge potential for making social and economic transactions more secure online by guarding against an attack and removing the need for any middleman. We want to build on Europe's substantial talent base and excellent startups to become a leading world region that will develop and invest in the rollout of blockchain.”
