Abstract.
Cloud computing has been tremendously successful in providing the
scalability needed for popular Internet-based services such as
Facebook, Google, and Netflix. Popular Internet-based services that we
use everyday rely on a public or private cloud platform to provide
their services world-wide. To scale out the system performance, these
services utilize hundreds of thousands to millions of servers that
cost billions of dollars. Effectively utilizing individual resources
in the cloud becomes crucial in reducing the cost (and the energy
consumption) at this scale.

In this talk, we look at how to improve the performance of a single
machine within the cloud. One of the key problems that limits the
performance is that applications and networking stacks are not design
to scale well in multicore environments. Modern machines have tens of
cores and multiple 10Gbps Ethernet links. However, existing designs
cannot effectively utilize these resources. In this talk, we focus on
improving the performance of two essential building blocks, an
in-memory key-value store and the TCP stack, that Internet-based
services commonly rely on. By employing multi-core aware designs and
by-passing the OS kernel to eliminate its overhead, we show that we
can dramatically increase their performances by up to 13.5x and 3x
respectively.


Bio:

Dongsu Han is an assistant professor at KAIST in the Department of
Electrical Engineering and the Graduate School of Information
Security. He received his Ph.D. from the Computer Science Department
at Carnegie Mellon University in 2012. His research interests include
Internet architectures, cloud and distributed systems, and Internet
content delivery. As part of this thesis work, he worked on a new
Internet architecture called XIA, one of the major, still on-going
future Internet architecture projects funded by the NSF.
