PhD Seminar • Data Systems — Energy Efficiency in Database Servers with Multi-core CPUsExport this event to calendar

Wednesday, October 31, 2018 — 12:15 PM EDT

Mustafa Korkmaz, PhD candidate
David R. Cheriton School of Computer Science

Data centers consume significant amounts of energy and consumption is growing each year. Alongside efforts in the hardware domain, there are some mechanisms in the software domain to reduce energy consumption. One of these mechanisms is dynamic voltage and frequency scaling (DVFS) and modern servers which are equipped with multi-core CPUs. 

In our previous work, we show that a DBMS can exploit its knowledge of the workload and performance constraints to obtain power savings that are more than twice as large as the power savings achieved when DVFS is managed by the operating system. 

In this talk, we present how we can exploit the multicore architecture of modern server CPUs to achieve further power savings in DBMS.
