[LA-SiGMA-TESC] Technologies for Extreme Scale Computing (TESC) seminar Thursday (6/19)

[Wei P Feinstein]

Hi all,


Our weekly TESC seminar this week will be held in 1008B Digital Media Center on Thursday (6/19) at 12:15pm-1:15pm.


This week's speaker is Dr. Feng Chen, an assistant professor from the Computer Science and Engineering Division. The topic is

"Client-aware Cloud Storage".


Abstract:

Cloud storage is receiving high interest in both academia and industry. As a new storage model, it provides many attractive features, such

as high availability, resilience, and cost efficiency. Yet, cloud storage also brings many new challenges. In particular, it widens the already

significant semantic gap between applications, which generate data, and storage systems, which manage data. This widening semantic

gap makes end-to-end differentiated services extremely difficult. In this talk, we present a client-aware cloud storage framework, which

allows semantic information to flow from clients, across multiple intermediate layers, to the cloud storage system. In turn, the storage system

can differentiate various data classes and enforce predefined policies. We showcase the effectiveness of enabling such client awareness

by using Intel's Differentiated Storage Services (DSS) to enhance persistent disk caching and to control I/O traffic to different storage devices.

We find that we can significantly outperform LRU-style caching, improving upload bandwidth by 5x and download bandwidth by 1.6x.

Further, we can achieve 85% of the performance of a full-SSD solution at only a fraction (14%) of the cost.

PIZZA AND DRINK WILL BE PROVIDED.
