Ineffective concurrency mechanisms in an operating
system can lead to low performance in both single
and multiprocessor environments. Practical setbacks
involved with attempting overly invasive kernel
changes have made it difficult in the past to
implement new and innovative concurrency systems.
This paper describes the rationale behind interfaces
in the DragonFly BSD operating system intended to
provide high performance and scalability on
multiprocessor architectures. Using a lock-free
processor centric approach, DragonFly BSD has
developed a unique thread system with the potential
for excellent scalability.
