How SMPng Works and Why It Doesn't Work The Way You Think, John Baldwin

Modern x86 CPUs have hit a wall in frequency scaling and are now
expanding sideways by adding more cores. Adding more cores does not
magically multiply performance, however. John talks about some of the
reasons that it doesn't.

In 2000, FreeBSD launched a project to multithread its kernel to more
fully take advantage of modern SMP machines. This talk will give an
overview of that project's history and continuing work on improving

About the speaker:
John first started using FreeBSD in 1996 and has been an active kernel
developer since 2000. He has worked for various companies that use
FreeBSD including The Weather Channel and Yahoo!. John lives in New
Jersey with his wife and three kids.


We are looking at doing an arm architecture hackfest.  Our preferred
hardware is the BeagleBone, although other hardware is certainly
welcome.  We're working out details and will have some more information
in the near future.


The holidays are usually about giving back, and feeling warm and nice
with family and friends.  But then there's the Grinch.  We all have it
in us.  Let it out of you.  Give ten minutes to let others know what you
"hate" and why.  The cloud?  Some scripting language or another?
Specific standards, or the lack of?

More details coming on this, but give it some thought.  There's at least
some things we all have our gripes about, and you'll have the
opportunity to voice your opinion, and maybe find a sympathetic audience.
