June 3 - FreeBSD's NUMA, John Baldwin
18:45, Stone Creek Bar & Lounge: 140 E 27th St
Newer x86 systems continue to scale horizontally by adding more cores
rather than vertically. This in turn has placed additional strain on
other system components such as memory controllers. The solution has
been to scale these components horizontally as well. This results in a
more complex system requiring additional tuning for optimal performance.
The first part of the talk will provide an overview of these extra-CPU
scaling changes in x86 systems. We will also talk about the resulting
performance impacts and some of the tradeoffs to consider when tuning.
The second part of the talk will focus on changes to FreeBSD to support
these system changes both in past releases and anticipated work in
Bring your facial tissues. The problems here are similar to those of
achieving optimal performance on systems with multiple CPUs, and we all
know how well that has worked out.
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 with a recent penchant for hacking on bhyve. John lives in New
Jersey with his wife and three kids.
