Keynote Title: Carving Reality at its Digital Joints

Abstract: We live much of our lives immersed in the world of made-up structures that we call Social Reality. In other words, much of our lives are governed by socially constructed (and, hence, to a certain extent fictional) entities such as money, citizenships, employments, enrolments, marriages, presidential mandates, legal liabilities, stock options and derivative transactions, etc. With the massive advance of information technology, much of social reality is now purely grounded in a world of symbolic manipulation of digital representations. Moreover, much of this digital existence is scattered in several independent information silos that were created in different organizational cultures, through independent engineering processes, in different moments in space and time. Finally, we are more and more delegating decisions that help to create social reality to autonomous artificial systems. This scenario raises several critical questions, for example: how can we create a unified view of social reality by putting together pieces of information that now reside in independent information silos, each of which potentially carving out reality in potentially different ways? How can we build autonomous information systems that we understand and trust, i.e., systems that reflect our values, and that are semantically transparent and able to explain their decisions? In this talk, I intend to argue that modern information systems engineering cannot succeed without the support of the 2400 years-old discipline of Ontology in philosophy, a discipline devoted to the systematic investigation of what exists in a system of representations.

Keynote Title: Out with the old: The cryptographic revolution caused by the threat of quantum computing

Abstract: Since its invention in the 1970s, public key cryptography has become a key security enabler: on the Internet, within enterprises, and enabling widespread secure communications. The benefits it brings in terms of enabling secure interoperation between entities with no prior relationship have been great, but came at a significant cost - public key cryptography has always been more computationally intensive than traditional secret key cryptography. Nonetheless, by the early 2000s - thanks to a range of innovations - we were in a world where standardised public key cryptography was very widely available. However, If and when large-scale general-purpose quantum computers are constructed, the effect on currently used public key cryptography will be very significant. In particular, Shor’s algorithm (published in 1994) has a very major impact on the security of all today’s widely used public key cryptography. This has led to large scale projects to develop new and practical techniques which will remain secure even in the presence of a quantum computer. Thanks to very major efforts across the cryptographic community, standards for new schemes are emerging which are already beginning to replace the vulnerable algorithms. This talk will explore the latest development and also the implications of this cryptographic revolution.

Keynote Title: Meeting Societal Challenges: Scalable Big Data-driven, AI- enabled Approaches

Abstract: By 2025, the total size of digital data generated by social networks, sensors, biomedical imaging and simulation devices, will reach an estimated 163 Zettabytes (e.g. 163 trillion gigabytes) according to IDC report. This type of 'big data', together with the advances in information and communication technologies such as data analytics/machine learning/AI, Internet of things (IoT), connected smart objects, wearable technology, ubiquitous computing, is transforming every aspect of modern life and bringing great challenges and spectacular opportunities to fulfil our dream of a sustainable smart society. This talk will focus on our latest developments and methods on scalable learning from large scale data and present real case studies to demonstrate how we applied big data driven, AI-enabled approaches in various application domains such as Health, Food to address society challenges.

Keynote Title: Investigating Chiplets for Scalable and Cost Effective HPC Beyond Exascale

Abstract: Chiplets have become a compelling approach to scaling and heterogeneous integration e.g. integrating workload-specific processors and massive bandwidth memory systems into computing systems; integrating die from multiple function-optimized process nodes into one product; integrating silicon from multiple businesses into one product. Chiplet-based products have been produced in high volume by multiple companies using proprietary chiplet ecosystems. Recently, the community has proposed several new standards (e.g., UCIe) to facilitate integration and interoperability of any compliant chiplet. Hyperscalers (e.g., Google, Amazon) are actively designing high volume products with chiplets through these open interfaces. Other communities are exploring the end-to-end workflow and tooling to assemble chiplet-based products. High performance computing can benefit from this trend. However, the performance, power, and thermal requirements unique to HPC, present many challenges to realizing a vision for affordable, modular HPC using this new approach.
