Introduction
to Multithreading and Multiprocessing in the FreeBSD SMPng Network Stack (370
Kb)
EuroBSDCon 2005 took place in Basel, Switzerland in November, 2005. Due to an injury, I
was unable to attend the conference itself, and my talks were presented in absentia by
Poul-Henning Kamp and Ed Maste, who have my greatest appreciation!
> The FreeBSD SMPng Project has spent the past five years redesigning and
reimplementing SMP support for the FreeBSD operating system, moving from a Giant-locked
kernel to a fine-grained locking implementation with greater kernel threading and
parallelism. This paper introduces the FreeBSD SMPng Project, its architectural goals and
implementation approach. It then explores the impact of SMPng on the FreeBSD network
stack, including strategies for integrating SMP support into the network stack, locking
approaches, optimizations, and challenges.
