Tech Talk : Joseph Koshy on FreeBSD

April 8th, 2009

ACM Tech Talk Abstract

PmcTools in FreeBSD is an innovative measurement platform that uses in-CPU hardware event counters for characterizing system behaviour. PmcTools’ low-overheads, useful features and its ability to collect data under production loads have helped it become an integral part of the performance analyst’s toolkit in FreeBSD. This talk introduces PmcTools. We start with a high-level overview of the goals of the project, and go on to cover the architecture of the PmcTools platform, its programming API and a few interesting aspects of its implementation. The changes to the base FreeBSD kernel needed for PmcTools are touched upon. The talk concludes with a discussion on the possible future directions of the project.
