Abstract
We are in the midst of a dramatic change in what computer systems look like. Our traditional view of computer systems composed of the CPU, main memory, and very slow storage device has recently be challenged with the advent of SSDs. Today, with the advent of nonvolatile memory, we are, possibly, anticipating an even more dramatic change in what computers of the future will look like. Such anticipated changes raises the question on how operating systems and their major components that, by nature, run on these systems will have to adapt to accommodate these changes. Should we continue to adapt and evolve the system that was designed 40-50 years ago based on our traditional view of computers, or should we start anew? Though I do not have the answer to this question, in this talk, I will share some of our experience on this topic based on some very initial studies that we have conducted.
 
Bio
Sam H.(Hyuk) Noh received the BS degree in computer engineering from the Seoul National University, Seoul, Korea, in 1986, and the PhD degree from the Department of Computer Science, University of Maryland, College Park, MD, in 1993. He held a visiting faculty position at the George Washington University, Washington, DC, from 1993 to 1994 before joining HongIk University, Seoul, Korea, where he was a professor in the School of Computer and Information Engineering until the Spring of 2015. Starting from the Fall of 2015 he joined the School of Electrical and Computer Engineering at UNIST (Ulsan National Institute of Science and Technology) where he is a Professor and Head of the School. From August 2001 to August 2002, he was also a visiting associate professor with the University of Maryland Institute of Advanced Computer Studies (UMIACS), College Park, MD. He has also served or serves as General Chair, Program Chair, and Program Committee Member on a number of technical conferences and workshops.
Most recently, he was General Chair of the ACM LCTES 2015, PC member for USENIX FAST from 2013 to 2016, and HotStorage in 2015. In 2016, he was the PC Chair for HotStorage, a member of the PC for ACM ASPLOS, and USENIX OSDI. He also served as Associate Editor of the ACM Transactions on Storage from 2014 to August 2016, and now serves as Editor-in-Chief. His current research interests include operating system issues pertaining to embedded/ computer systems with a focus on the use of new memory technologies such as flash memory and persistent memory. He is a member of the ACM, IEEE, USENIX, and KIISE.
