Scaling: Up, Down, and Both

Linux's scalability has improved greatly over the past ten years, but much work remains. Yes, the Big Kernel Lock is finally almost completely removed, but there are a number of “little kernel locks” throughout the kernel. Some of these are being worked, for example, Nick Piggin's work breaking up dcache_lock and d_lock, but others need help as well.

But the increasing use of Linux in the embedded arena highlights the need to scale down as well as up. In fact, given the arrival of multicore embedded CPUs, Linux must scale both up and down simultaneously, preferably while still maintain good response times.

This microconference will therefore look at efforts to scale up, down, and in both directions simultaneously.
