Location:    SIST 1A 200

Host:            Prof. Chundong Wang

Abstract:

This seminar is to describe the challenges in processing ultra-scale data streams from giant scientific apparatuses such as Shanghai Synchrotron Radiation Facility (SSRF) and Five-hundred Aperture Sphere Telescope  (FAST).  With the experience gained in the process of designing Square Kilometre Array (SKA) radio telescope (SKA), we will explore how custom computing methods handle the bottlenecks of data transmission and processing. We propose to optimize variable precision computing and compression in the form of customized methods for data preprocessing and compression. We also propose to design a write-in method for next generation network in order to achieve better receiving capacity. We further propose to work on parallelization of image reconstruction and key radiotelescope data processing algorithms by accelerating on GPU and FPGA. Our design and implementation will be validated on-site at stations of SSRF and FAST to resolve the bottlenecks of transmission and processing of ultra-scale scientific data streams.

Dr. Zhu joined Shanghai Advanced Research Institute, Chinese Academy of Sciences (CAS) as full Professor in 2017. He is also an Adjunct Professor with the School of Microelectronics at the Shanghai Jiao Tong University (SJTU). He has published over 170 English journal and conference papers, 50 Chinese journal papers and 20 China patent approvals in the areas of computer architecture, embedded systems and big data processing. With over 1500 citations of these works in recent years, he has received recognition in China and Asia with IEEE best paper award, Shanghai innovation award, SJTU Annual Outstanding Teacher Award and Bilingual Teaching Award. To date, he has received around 30 million RMB in grants from various funding agencies and industrial partners in China. Prior to his tenure with CAS and SJTU, he worked as a research fellow with National University of Singapore in 2002-2005, a senior consultant with S1 Incorporation (inventor of the 1st Internet banking in the world) in 1999-2002 and a teaching assistant with the Department of Computer Science and Engineering, SJTU in 1994-1995. He has served as a guest editor of Journal of Systems Architecture, program chairs of more than 10 conferences, a distinguished member of China Computer Federation (CCF) and senior member of IEEE. He has been also a Visiting Professor with National University of Singapore since 2013.
