From george at ceetonetechnology.com Mon Jun 1 20:00:47 2015 From: george at ceetonetechnology.com (George Rosamond) Date: Mon, 01 Jun 2015 20:00:47 -0400 Subject: [talk] NYC*BUG: John Baldwin on NUMA and more Message-ID: <556CF22F.1010104@ceetonetechnology.com> For the first time in a long time, we will hold two meetings in a month, plus a social event, with BSDCan in between. Note: if you are going to BSDCan, please bring any HDMI-compatible LCDs for hardware hacking. There will be enough cables, but displays are greatly needed. ************************** June 3 - FreeBSD's NUMA, John Baldwin 18:45, Stone Creek Bar & Lounge: 140 E 27th St Abstract 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 future releases. 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. Speaker Bio 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.

Today, mandoc is the standard manual page formatter in OpenBSD, FreeBSD, NetBSD, DragonFly, illumos, and Void Linux, and OpenBSD also uses it as the manual page viewer man(1), as the manual page search tool apropos(1)/makewhatis(8), and as man.cgi(8) to search and display manual pages on the web. It now produces ASCII, UTF-8, HTML5, MathML, PostScript, PDF, and man(7) output. Given that manual page toolkits existed for almost four decades before Kristaps even started, how could such an overfulfillment of expectations possibly happen, and what lessons were learnt in the process? Topics of this meeting include: - importance of and requirements for software documentation - history of roff/man/mdoc, and why they remain the best doc tools - features of mandoc, both seasoned and new ones - mandoc development and system integration, or how to lead a software package to success - mandoc adoption in various operating systems and possible future directions The talk is designed as a best-of selection of content shown at BSDCan 2011, 2014 and 2015 and EuroBSDCon 2014. After the presentation, you are welcome to optionally stay for a hands-on workshop, so be sure to bring your notebook. You might wish to hunt for markup bugs in operating system manuals, or you might wish to work on format conversions from legacy formats to mdoc(7), and if you already have some experience, there are more ideas, see for example pages 40-43 of http://www.openbsd.org/papers/eurobsdcon2014-mandoc-paper.pdf. In any case, there is a chance to do some work that results in your first commit into your favourite operating system - that did happen at a similar workshop held at EuroBSDCon 2014 in Sofia/Bulgaria... Speaker Bio Ingo Schwarze is the current maintainer of the mandoc(1) documentation toolbox developed by Kristaps Dzonsons. He also maintains the OpenBSD groff(1) port and has contributed to various parts of the OpenBSD userland, for example the Perl rewrite of the security(8) script, as well as smaller contributions to the rc.d(8)/rcctl(8) framework, the yp(8) subsystem, the C library, and various other programs. After studying in Siegen (supervisor: Prof. Martin Holder), Ingo Schwarze worked in experimental and theoretical high energy physics at CERN (NA48) and in Karlsruhe.

Nice stuff, a bit automagic for my tastes.. The brocade switches had a number of tools for disovering/reporting the current state of all the trill/link measures, l2traceroute was the name of one of their commands, etc... -- From a visualization perspective, a very cool guy from Ohio State univ. showed me some wicked homegrown network visualizations of their state network backbones- some of the best stuff I've ever seen actually. It's SVG, and uses javascript to draw from live stats in a browser window. I'm *very* sad to say I've forgotten this guy's name, but would love help tracking him down- I was pestering him to open the SVG/base parts up as a BSD licenced thing, (particularly since the state paid for it to be built...) Does anyone attending BSDCan remember the dude I'm referring to? Glasses, medium fro of curly hair, young guy, Ohio... Really cool guy.
