“Edge Computing as a Missing Link in the Post Moore Era”

Wednesday 15 February, 10.30am – 11.05am


In the first part of this talk talk we discuss the concept of extreme performance HPC where the applications often include latencies below 100 ms or even below 10 ms. To facilitate low latency computation has to be placed in the vicinity of the end users by utilizing the concept of Edge Computing. We present the novel failure resilience mechanisms applied to Edge systems considering timeliness, hyper-heterogeneity and resource scarcity. We discuss our machine learning based mechanism that evaluates the failure resilience of a service deployed redundantly on the Edge infrastructures. Our approach learns the spatiotemporal dependencies between Edge server failures and combines them with the topological information to incorporate link failures by utilizing the concept of the Dynamic Bayesian Networks (DBNs). Eventually, we infer the probability that a certain set of servers fails or disconnects concurrently during service runtime. The robustness of the approach has been evaluated using the concept of code offloading.

In the second part we discuss the potential impact of Edge Computing in the current rise of highly specialized architectures ranging from neuromorphic to quantum computing. As we experience the paradigm shift from generalized architectures of the Von Neumann era to highly specialized architectures in the Post-Moore’s law era we expect the coexistence of multiple types of architectures specialized for different types of computation. We define the two of the architectures that attracted the most interest in the research community, where we witness not only theoretical developments but also first implementations and practical use cases. Afterward, we discuss the first ideas but also challenges in the integration of identified architectures into existing HPC systems.


Ivona Brandic is University Professor for High Performance Computing Systems at the Institute of Information Systems Engineering, Vienna University of Technology (TU Wien) where she leads High Performance Computing Systems Research Group. In 2015 she was awarded the FWF START prize, the highest Austrian award for early career researchers. Since 2016 she has been a member of the Young Academy of the Austrian Academy of Sciences.

From 2002 to 2007 she was Assistant Professor at the Department of Scientific Computing, University of Vienna.
From 2007 to 2014 she was Assistant Professor at the Institute of Information Systems, TU Vienna. From 2014 to 2015 she was Assistant Professor at the Institute for Software Technology and Interactive Systems. She received her PhD degree in 2007 and her venia docendi for practical computer science in 2013, both from Vienna University of Technology. From 2009 to 2012 she led the Austrian national FoSII (Foundations of Self-governing ICT Infrastructures) project funded by the Vienna Science and Technology Fund (WWTF). She was a management committee member of the European Commission’s COST Action on Energy Efficient Large Scale Distributed Systems and of the COST Action on Sustainable Ultrascale Computing (NESUS). From June to August 2008 she was visiting researcher at the University of Melbourne, Australia. I. Brandic was on the Editorial Board of IEEE Magazine on Cloud Computing, IEEE Transactions on Parallel and Distributed Systems and IEEE Transactions on Cloud Computing.

In 2011 she received the Distinguished Young Scientist Award from the Vienna University of Technology for her project on the Holistic Energy Efficient Hybrid Clouds. Her interests comprise virtualized HPC systems, energy efficient ultra-scale distributed systems, massive-scale data analytics, Cloud & workflow Quality of Service (QoS), and service-oriented distributed systems. She published more than 50 scientific journal, magazine and conference publications and she co-authored a text-book on federated and self-manageable Cloud infrastructures. I. Brandic co-authored the European Union’s Cloud Computing report paving the future research directions of the EU. She has been serving more than 50 program committees among others Supercomputing, CCGrid, EuroPar, and IPDPS. She was invited reviewer of more than 10 renowned international journals among others IEEE Transactions on Parallel and Distributed Systems, IEEE Transactions on Service Computing, Future Generation Computer Systems, and IEEE Transactions on Computers. I. Brandic has been invited expert evaluator of the European Commission, French National Research Organization (ANR), National Science and Engineering Research Council Canada (NSERC), Netherlands Organization for Scientific Research (NWO), Australian Research Council (ARC), Research Foundation – Flanders (FWO), Ontario Research Fund, Israel Science Foundation (ISF), Portuguese national funding agency for science, research and technology (PTF) and Swedish Foundation for Strategic Research (SSF). In 2019 she chaired the CHIST-ERA panel (ANR) on Smart Distribution of Computing in Dynamic Networks (SDCDN).

She is a board member of the Center for Artificial Intelligence and Machine Learning (CAIML) and a faculty member of the Vienna Center for Engineering in Medicine (ViCEM).
