Hardware Performance Monitoring Counters

6:30pm, Suspenders Restaurant
http://www.suspendersbar.com/location.php

Many modern CPUs provide on chip counters for performance events such as
retiring instructions and cache misses. The hwpmc driver and libraries
in FreeBSD give systems administrators and programmers access to APIs
which make it possible to measure performance without modifying source
code and with minimal intrusion into application execution. This talk
will be a brief introduction to HWPMC, and how to use it.

George Neville-Neil is the co-author with Kirk McKusick of The Design
and Implementation of the FreeBSD Operating System. He works on
networking an operating systems for fun and profit.
