[PDL/SDI] Fall 2019: Hideaki Kimura (Oracle)

This talk gives an overview of Oracle NVM Direct, an open source implementation of a C API to simplify application development for byte addressable Non Volatile Memory. NVM Direct consists of two major components, namely: A precompiler that converts a source file containing C extensions for NVM to a standard C source file. A runtime library to implement NVM regions, heaps, locks, and transactions. Some of the functions are called by code inserted by the precompiler, and some are called Read More

[DB Seminar] Fall 2019 DB Group: Shasank Chavan (Oracle)

Autonomous / Self-Driving Databases utilize machine learning techniques to eliminate the manual labor associated with database tuning, security, backups, updates, and other routine management tasks traditionally performed by DBAs. This talk will focus specifically on how we implement a self-performing database with Oracle’s Database In-Memory product to automatically tune for query optimization, memory management, and storage management and data tiering. We will first present Oracle’s Database In-Memory architecture and various features built for optimizing analytics and mixed workload performance, and Read More

Fall 2019: Vagelis Papalexakis (UC Riverside)

Tensors and tensor decompositions have been very popular and effective tools for analyzing multi-aspect data in a wide variety of fields, ranging from Psychology to Chemometrics, and from Signal Processing to Data Mining and Machine Learning. Using tensors in the era of big data presents us with a rich variety of applications, but also poses great challenges, especially when it comes to scalability and efficiency.In this talk, we will demonstrate the effectiveness of tensor decompositions as data analytic tools in Read More

PhD Defense: Huanchen Zhang

The growing cost gap between DRAM and storage together with increasing database sizes means that database management systems (DBMSs) now operate with a lower memory to storage size ratio than before. On the other hand, modern DBMSs rely on in-memory search trees (e.g., indexes and filters) to achieve high throughput and low latency. These search trees, however, consume a large portion of the total memory available to the DBMS. This dissertation seeks to address the challenge of building compact yet Read More
