Talk Title: Modernizing Storage Systems for Big Data Applications
Abstract: Existing high-speed non-volatile storage systems leverage entrenched system stack developed for magnetic hard disk drive, leading to suboptimal performance and under-utilized system resources. As data set sizes of applications keep increasing, using conventional system stack for modern storage devices becomes a new performance bottleneck. For example, a database system can spend 80% of time in just fetching data from the storage system, leaving precious computing resource idle at the same time.
To improve the performance of serving data from storage systems, we need to revisit the block-based storage interface designed for slower, magnetic disk drives. In this talk, Hung-Wei will share his experience in modernizing the hardware/software interface for storage systems and achieve performance gain in computer systems. Hung-Wei will introduce his research projects including: (1) HippogriffDB, a GPU-based database system that balances the huge gap between the throughputs of the GPU and the SSD. (2) Morpheus-SSD that utilizes computing resources inside storage devices to create more efficient applications. (3) KAML that modernizes the conventional block-based I/O with a keyvalue-like interface.
Biography: Hung-Wei is currently an assistant professor in the Department of Computer Science and Department of Electrical and Computer Engineering, NC State University where he is now leading the Extreme Storage & Computer Architecture Laboratory. Prior to joining NCSU, Hung-Wei was a postdoctoral scholar of the Non-volatile Systems Laboratory with Professor Steven Swanson and a lecturer of the Department of Computer Science and Engineering at University of California, San Diego. His thesis work with Professor Dean Tullsen, data-triggered threads, was selected by IEEE Micro "Top Picks from Computer Architecture" in 2012.

Viterbi Distinguished Lecture

Speaker: Professor Peter Shor, MIT
Talk Title: Capacities for Quantum Communication Channels
Series: Viterbi Lecture
Abstract: In 1948, Shannon discovered his famous formula for the capacity of a communication channel. This formula does not apply, however, to channels with significant quantum effects. For quantum channels, the question of capacity is much more complicated, as there are different capacities for sending classical information and for sending quantum information. We will discuss the capacities of quantum channels, and survey the historical development of the subject.
Biography: Peter Shor received a B.S. in Mathematics from Caltech in 1981, and a Ph.D. in Applied Mathematics from M.I.T. After a one-year postdoctoral fellowship at the Mathematical Sciences Research Institute in Berkeley, he took a job at AT&T Bell Laboratories, and stayed at AT&T until 2003. In 2003, he went to M.I.T., where he is the Morss Professor of Applied Mathematics.
Until 1994, he worked on algorithms for conventional computers and did research in probability and combinatorics. In 1994, after thinking about the problem on and off for nearly a year, he discovered an algorithm for factoring large integers into primes on a quantum computer (still hypothetical, but steadily becoming less so). Since then, he has mainly been investigating quantum computing and quantum information theory.
Among other awards, he has received the Nevanlinna Prize, the Goedel prize, and a MacArthur Fellowship. He is a member of the American Academy of Arts and Sciences and of the National Academy of Sciences.
