DSG Seminar Series • Improving Understanding and Exploration of Data by Non-Database Experts

Rachel Pottinger, Department of Computer Science
University of British Columbia

Users are faced with an increasing onslaught of data, whether it's in their choices of movies to watch, assimilating data from multiple sources, or finding information relevant to their lives on open data registries.

DSG Seminar Series • Speedup Set Intersections in Graph Algorithms using SIMD Instructionsnotes

Lei Zou, Institute of Computer Science and Technology
Peking University

​In this talk, I focus on accelerating a widely employed computing pattern — set intersection, to boost a group of relevant graph algorithms. Graph’s adjacency-lists can be naturally considered as node sets, thus set intersection is a primitive operation in many graph algorithms. We propose QFilter, a set intersection algorithm using SIMD instructions. QFilter adopts a merge-based framework and compares two blocks of elements iteratively by SIMD instructions.

Machine vs. human generated data

Curt Monash has recently been discussing the differences between machine-generated data and human-generated data, and trying to define these terms on his blog. I think this is a good subject to dive into, since I frequently use the existence of machine-generated data to justify to myself why 90% of my research cycles are spent on scalability problems in database systems. Rather than try to fit a response as a comment on his post, I thought I would devote a post to this subject here.
