PhD Defence • Data Systems • Memory Power Consumption in Main-Memory Database Systems

Please note: This PhD defence will take place online.

Alexey Karyakin, PhD candidate
David R. Cheriton School of Computer Science

Supervisor: Professor Ken Salem

In main-memory database systems, memory can consume a substantial amount of power, comparable to that of the processors. However, existing memory power-saving mechanisms are much less effective than processor power management. Unless the system is almost idle, memory power consumption will be high.

Dean’s Distinguished Visiting Professor Lecture • Riding Along with the Time-traveling Networking Researcher

Please note: This lecture will take place in DC 1302 and online.

Mostafa H. Ammar, Regents’ Professor
School of Computer Science, Georgia Institute of Technology

A networking researcher, traveling forward in time from 1985 to the present, would be shocked by many things — not the least of which is the fact that people are still doing networking research in 2022.

PhD Seminar • Human-Computer Interaction • Conductor: Intersection-Based Bimanual Pointing in AR and VR

Please note: This PhD seminar will take place in DC 1304 and online.

Futian (Caesar) Zhang, PhD candidate
David R. Cheriton School of Computer Science

Supervisors: Professors Jian Zhao, Keiko Katsuragawa

Pointing is an elementary interaction in virtual and augmented reality environments, and, to effectively support selection, techniques must deal with the challenges of occlusion and depth specification. Most of the previous techniques require two explicit steps to handle occlusion.

Seminar • Systems and Networking • Ledgers, Machines, and Markets

Please note: This seminar will take place in DC 1302.

Yaron Minsky, Jane Street

The rise of blockchain has led to a renewed interest in the use of ledgers as a basic data-structure for building distributed systems.

But the use of ledgers to build distributed systems is a very old idea, playing an important role in both academic computer science (in the guise of state machine replication) and in real-world financial technology.
