| 題目(Title) | Real-Time Micro-service Operating Infrastructure for Scientific Workflows |
| 概要(Abstract) | Studies suggest that it typically takes 20 years to go from the discovery of new materials to fabrication of new and next generation devices based on new materials. Many other scientific domains show similar delays. These scientific cycles must be shortened, and it will require a major transformation in how we collect digital data about materials and other physical artifacts from scientific instruments, and how we make the digital data available to computational tools for developing new materials, fabricating new devices, and speeding up the discoveries in science. In this talk we present a real-time micro-service operating infrastructure for scientific workflows, named 4CeeD, that focuses on the immense potential of capturing, accurately curating, correlating and coordinating digital data in a real-time and trusted manner before fully archiving and publishing them for wide access and sharing. We will discuss novel services, models and algorithms that are an integral part of 4CeeD such as (a) the curation service for collecting and correlating data from microscopes and fabrication instruments, (b) modeling of scientific workflows in clouds as micro-services, and (c) self-adaptive micro-service based infrastructure for heterogeneous scientific workflows. Especially, we will show that: (1) our micro-service based approach helps the 4CeeD system to improve flexibility of workflow composition and execution, and enable fine-grained scheduling at task level, considering task sharing across multiple workflows; (2) the self-adaptive micro-service management employs feedback control approach to offer resource adaptation without any advanced knowledge of workflow structures using deep learning and optimization within the feedback control loop; (3) the evaluation of the 4CeeD system on multiple workflows shows robust dealing with dynamic workload. |

Her research interests are directed toward advanced cloud-based cyberinfrastructures for scientific instrumentation, multi-camera tele-immersive systems, end-to-end Quality of Service (QoS) and resource management in large scale distributed systems and networks, and real-time security and privacy in cyber-physical systems such as power grid. She is the co-author of multimedia books `Multimedia: Computing, Communications and Applications' published by Prentice Hall, and ‘Multimedia Systems’ published by Springer Verlag. She is the recipient of the IEEE Communication Society Leonard Abraham Award for Research Achievements, University Scholar, Humboldt Award, IEEE Computer Society Technical Achievement Award, ACM SIGMM Technical Achievement Award, and the former chair of the ACM Special Interest Group in Multimedia. She was the general co-chair and TPC co-chair of many international conferences including ACM Multimedia, IEEE Percom, IEEE IOTDI and others. Klara Nahrstedt received her Diploma in Mathematics from Humboldt University, Berlin, Germany in numerical analysis in 1985. In 1995 she received her PhD from the University of Pennsylvania in the Department of Computer and Information Science. She is ACM Fellow, IEEE Fellow, and Member of the German National Academy of Sciences (Leopoldina Society). |
