Computer Systems and Engineering Seminar Series

It's the I/O, stupid.

Speaker:Dr. Hung-Wei Tseng
Date: Monday, October 23, 2017
Time: 12:00pm - 1:00pm
Location: 212 Hudson Hall, Duke
Lunch served at 11:45


With massive parallel processing and heterogeneous computing significantly shrinking the computation time but increasing the amount of data movement in the system, the bottleneck of running applications shifts to the I/O. As a result, applications may underutilize system components, especially when the computer needs to deal with a huge amount of data. In this talk, Hung-Wei will introduce his work in improving the data exchange among system components which can speedup database applications by up to 250x. Hung-Wei will also talk about through revisiting the hardware/software interface between data storage and the host computer, we can improve key-value store performance by 2.5x. Hung-Wei will also demonstrate by rethinking the roles of data storage and computing devices inside the computer, we can accelerate general-purpose benchmark applications by 1.39x.


Hung-Wei Tseng is currently an assistant professor in the Department of Computer Science, 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.
