|
Zhiwei Xu is a professor and CTO of the Institute of Computing Technology (ICT) of the Chinese Academy of Sciences (CAS). His prior industrial experience included chief engineer of Dawning Corp. (now Sugon as listed in Shanghai Stock Exchange), a leading high-performance computer vendor in China. He currently leads “Cloud-Sea Computing Systems”, a strategic priority research project of the Chinese Academy of Sciences that aims at developing billion-thread computers with elastic processors. Zhiwei Xu holds a Ph.D. degree from the University of Southern California, an MS degree from Purdue University, and a BS degree from University of Electronic Science and Technology of China.
Research Interest
My long-term research interest is computing for the masses (C4M): empowering 80% of population with advanced information technology (IT). C4M needs five pillars, which are yet to be built by the IT community and users. They are:
- Ternary Computer Science of computational processes in the Human-Cyber-Physical Ternary universe (the Net of people, bits and things), not just in the cyberspace.
- A tetherless, seamless, life-time Universal Compute Account for everyone to access the Net.
- Lean System Platforms, a near-term efficiency goal is trillion operations per Joule.
- A Science of the Net Ecosystem that helps to sustain an open and safe Net with growing community assets. A starting point is to study norm forms enabling safety and sharing.
- A National Information Accounts system that learns from the national economic accounts system, and helps understand the stocks and flows of data resources, goods, services.
