DSG Seminar Series • Adaptive Join Order Optimization Using Search Space Linearization

Please note: This DSG Seminar Series talk will be given online.

Thomas Neumann, Department of Computer Science
Technical University of Munich

Join ordering is one of the core problems of query optimization, as differences in join order can affect the execution time of queries by orders of magnitudes. Unfortunately, the problem is NP hard in general, and real-world queries can join hundreds of relations, which makes exact solutions prohibitive expensive.

Crash Course on WiCS

Please note: This talk will be given online.

Jo Atlee, Professor and Director of Women in Computer Science
David R. Cheriton School of Computer Science

This talk looks at some of the issues of equity, diversity, and inclusiveness that women in computing face, in K-12, in university, and as junior programmers in the workforce. I’ll discuss some of the best practices for addressing these issues, what WiCS is doing to address these issues, and the considerable amount of work that is left to do.

Seminar • Systems and Networking • Rethinking Modern Storage and Memory Management

Please note: This seminar will be given online.

Sudarsun Kannan, Department of Computer Science
Rutgers University

The last decade has seen a rapid hardware innovation to develop ultra-fast and heterogeneous storage and memory technologies for accelerating data-intensive applications. Unfortunately, current monolithic system software stacks with coarse-grained synchronization, high data movement costs, and inflexible abstractions continue to be Achille’s heel, thereby failing to exploit hardware innovations.
