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. In this talk, I will discuss the happenings on system software research related to nonvolatile memory. In the process, I will share experiences and results from some recent work that we, at the NECSST (Nextgeneration
Embedded/Computer System Software Technology) lab, have been conducting in regards to SSDs and nonvolatile memory. In particular, some of the topics that I wish to cover (time permitting and subject to change) are SSD array configurations for network attached storage systems, empirical observations on a nonvolatile based system, an indexing structure for nonvolatile memory, and file systems and a persistency model for nonvolatile memory based systems.


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 UNIST (Ulsan National Institute of Science and Technology), a young Science and Tech focussed national university, where he is a Professor and Head of the School of Electrical and Computer Engineering. 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 served as General Chair, Program Chair, and Program Committee Member on a number of technical conferences and workshops including the ACM Operating Systems Design and Implementation (OSDI: 2016), ACM Architectural Support for Programming Languages and Operating Systems (ASPLOS: 2018(ERC), 2016), USENIX HotStorage (2016 (co-chair), 2015), USENIX Conference on File and Storage Technologies (FAST: 2018, 2017, 2016, 2105, 2014, 2013), Eurosys (2018), ACM SIGPLAN Conference on Languages, Compilers, and Tools for Embedded Systems (LCTES: 2015), IEEE International Conference on Parallel and Distributed Systems (ICPADS: 2013), and International World Wide Web (WWW: 2003) Conference. He has also been serving as Editor-in-Chief of the ACM Transactions on Storage since the summer of 2016.

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 (Senior), USENIX, and KIISE. (E-mail: samhnoh at unist dot ac dot kr)
