Core counts keep rising, and that means that the Linux kernel continues
to encounter interesting performance and scalability issues. Which is
not a bad thing, since it has been fifteen years since the "free lunch"
of exponential CPU-clock frequency increases came to an abrupt end.
During that time, the number of hardware threads per socket has risen
sharply, approaching 100 for some high-end implementations. In
addition, there is much more to scaling than simply larger numbers of
Proposed topics for this microconference include optimizations for
mmap_sem range locking ; clearly defining what mmap_sem protects
; scalability of page allocation, zone->lock , and lru_lock; swap
scalability; variable hotpatching (self-modifying code!);
multithreading kernel work; improved workqueue interaction with CPU
hotplug events; proper (and optimized) cgroup accounting  for
workqueue threads; and automatically scaling the threshold values for
We are also accepting additional topics. In particular, we are curious
to hear about real-world bottlenecks that people are running into, as
well as scalability work-in-progress that needs face-to-face discussion.
We hope to see you there!
LPC  will be held in Vancouver, British Columbia, Canada from
Tuesday, November 13 through Thursday, November 15.
