	    <title>EuroBSDCon 2008 - George Neville-Neil - Multicast Performance in FreeBSD</title>

	    <desc>

		In the past ten years most of the research in network

		protocols has gone into TCP, leaving UDP to languish

		as a local configuration protocol. While the majority

		of Internet traffic is TCP, UDP remains the only

		IP protocol that works over multicast and as such

		has some specific, and interesting uses in some

		areas of computing. In 2008 we undertook a study

		of the performance of UDP multicast on both 1Gbps

		and 10Gbps Ethernet networks in order to see if

		changing the physical layer of the network would

		give a linear decrease in packet latency. To measure

		the possible gains we developed a new network

		protocol test program, mctest, which is capable of

		recording packet round trip times from many hosts

		simultaneously and which we believe accurately

		represents how many environments use multicast. The

		mctest program has been integrated into FreeBSD and

		is now being used to verify the proper operation

		of multicast on various pieces of 10Gbps hardware.

	    <title>EuroBSDCon 2008 - Pedro Giffuni - Working with Engineering Applications in FreeBSD</title>

	    <desc><![CDATA[

		In recent years, traditional branches of engineering

		like Civil, Chemical, Mechanical, Electrical and

		Industrial Engineering are requiring extensive

		computing facilities for their needs. Several well

		known labs (Sandia, Lawrence Livermore) rely on

		huge clusters to do all types of complex analysis

		that were unthinkable a couple of decades ago. While

		the free BSD variants share the environment with

		traditional UNIX systems, frequently used for such

		computations, it was not common to find adequate

		free software packages to carry complex calculations.

		Eventually commercial versions of important math

		related packages started to appear for the Linux

		platform. Even when the big packages were distant,

		the BSDs learned and adapted in resourceful ways:

		Matlab and Mathematica, running under Linux emulation,

		demanded functionality from the BSDs and NetBSD

		implemented a signal trampoline to be able to run

		AutoCAD with IRIX binary compatibility. A notable

		project that was always available under a free

		license was Berkeley's Spice circuit analysis

		program, however it was an exception rather than

		the rule. Even when the scientific community pressed

		for a while to get other important tools like NASA's

		FEA package Nastran under a free license, the

		objective of being able to access and enhance open

		scientific tools was elusive. About a decade ago

		the situation started to improve: FreeBSD's ports

		system started growing exponentially, first with a

		high content in the math category, afterwards with

		a CAD section and after sustained growth in those

		categories a science section was created. This

		growth was mostly pushed by Universities and their

		research projects and in general are not well known

		with respect to the commercial counterparts. I

		started porting math/engineering code for FreeBSD

		around 1996. Back then it was absolutely unthinkable

		for a Mechanical Engineer to depend only on FreeBSD

		for it's daily work. The situation nowadays is

		different: there are some very high quality engineering

		analysis packages like EDF's Code Aster, with more

		than 12 years of professional development, that

		just can't be ignored. A Finite Element package,

		like Code Aster, can easily cost 5000 US$, is priced

		according to the maximum problem size it can solve,

		can require yearly licenses, and is rarely available

		with source code. In NASTRAN's case the source code

		is only available for US citizens under a yearly

		fee. Free software does have serious limitations

		though; just like in office applications there are

		proprietary CAD formats or sometimes the package

		simply doesn't have the required functionality.

		Having the sources, of course, always has the

		advantage of being able to implement (or pay for)

		some specific functionality you might need. Many

		commercial packages have been recently ported to

		Linux, but even when they gain some of the advantages

		of an open environment they still have yet another

		limitation: they have been very slow to make use

		of the multicored features of the new processors

		in the market, a huge limitation now that the speed

		war between processors has been limited by the

		overheating problem. The objective of the talk is

		to give an overview of several CAD/CAE packages

		that have been made available recently as part of

		FreeBSD's ports system and the decisions that were

		made to port them. BRLCAD and Varkon are two CAD

		utilities that made a transition from closed source

		to an open environment and in the process in the

		process of getting ported to BSD have gained greater

		portability and general "bug" fixes critical for

		their consolidation as usable and maintainable

		projects. There are also some tricks that have not

		been well documented: it is possible to enable

		threads and some extra optimizations on some packages,

		and it is also possible to replace the standard

		BLAS library with the faster GOTO BLAS without

		rebuilding the package. It is also possible to build

		the packages optimized for a clustered environment,

		but perhaps what is most interesting of all is how

		all the packages interrelate with each other and

		can turn FreeBSD into a complete enginering

		environment. No OS distribution so far is offering

		all the engineering specific utilities offered

		through FreeBSD's ports system: from design to

		visualization, passing through analysis FreeBSD is

		becoming an option that can't be ignored, and best

		of all, it is an effort that will benefit not only

		FreeBSD but the wider audience.

		Pedro F. Giffuni M. Sc. Industrial Engineering -

		University of Pittsburgh Mechanical Engineer -

		Universidad Nacional de Colombia I was born in

		Bogota, Colombia but I am an Italian citizen. My

		experience with computers started when I was about

		12 years old With the TRS-80 Color Computer first

		using Basic and the OS-9. I studied electronics for

		3 years but became tired of worrying about "whatever

		happened to electrons in there" and moved to

		Mechanical Engineering. For a while I rested from

		the computer world until the Internet came stepping

		along. I started using FreeBSD around 1995 and soon

		fell in love with the idea of being able to install

		a complete version of UNIX from the net with just

		one floppy. After submitting a the 999th port to

		the FreeBSD project Walnut Creek was kind enough

		to give me a subscription for several years to

		FreeBSD's CD-ROM. Since then I've been on and off

		porting software packages or fixing the bugs I have

		caused while porting them. Of course there has

		always been great respect for the other BSDs and

		their wonderful license and while I've given up on

		the idea of one day seeing a "UnifiedBSD" I am glad

		to see different approaches sharing ideas in a

		healthful environment.

	    <desc><![CDATA[

		In this talk, we will discuss the past and present

		history and the design principles of the OpenBSD

		hardware sensors framework. Sensors framework

		provides a unified interface for storing, registering

		and accessing information about hardware monitoring

		sensors. Sensor types include, but are not limited

		to, temperature, voltage, fan RPM, time offset and

		logical drive status. The framework spans

		sensor_attach(9), sysctl(3), sysctl(8), sensorsd(8),

		ntpd(8), snmpd(8) and more than 67 drivers, ranging

		from I2C temperature sensors and Super I/O hardware

		monitors to IPMI, RAID and SCSI enclosures. Several

		third-party tools are also available, for example,

		a plug-in for Nagios and ports/sysutils/symon.

		Originally based on some ideas from NetBSD, the

		framework has sustained many improvements in OpenBSD,

		and was ported and committed to FreeBSD and DragonFly

		BSD.

		The arrival of high CPU core density, with commodity

		quad-core notebooks and 32-core servers, combined

		with 10gbps networking have transformed network

		design principles for operating systems. This talk

		will describe changes in the FreeBSD 6.x, 7.x, and

		forthcoming 8.x network stacks required to exploit

		multiple cores and serve 10gbps networks. The goal

		of the session will be to introduce the audience

		to general strategies used to improve performance,

		their rationales, and their impact on applications

		and users:

		<ul>

		<li>Introduction to the SMPng Project and the follow-on Netperf Project

		<li>Workloads and performance measurement

		<li>Efficient primitives to support modern network stacks

		<li>Multi-core and cache-aware network memory allocator

		<li>Fine-grained network stack locking

		<li>Load-balancing and contention-avoidance across multiple CPUs

		<li>CPU affinity for network stack data structures

		<li>TCP performance enhancements including TSO, LRO, and TOE

		<li>Zero-copy Berkely Packet Filter (BPF) buffers

		<li>Direct network stack dispatch from interrupt handlers

		<li>Multiple input and output queues

		</ul>

		Robert Watson is a researcher at the University of

		Cambridge Computer Laboratory investinging operating

		system and network security. Prior to joining the

		Computer Laboratory to work on a PhD, he was Senior

		Principal Scientist at McAfee Research, now SPARTA

		ISSO, a leading security research and development

		organization, directing government and commercial

		research contracts for customers that include DARPA,

		the US Navy, and Apple Computer. His research

		interests include operating system security, network

	    <title>EuroBSDCon 2008 - Martin Schuette - Improved NetBSD Syslogd</title>

	    <desc><![CDATA[

	    Martin Schuette has three main goals, defined by three

	    internet drafts to implement:

	    <ul>

	    <li>TLS transport is the most obvious improvement: it

	    provides a reliable network transport with data encryption

	    and peer authentication. To make full use of this a

	    buffering mechanism to bridge temporary network errors

	    is implemented as well.

	    <li>Syslog-protocol extends the message format to use

	    a complete timestamp, include a fully qualified domain

	    name, and allow UTF-8 messages. It also offers a

	    structured data field to unambiguously encode application

	    dependent information.

	    <li>Syslog-sign will allow any syslog sender to digitally

	    sign its messages, so their integrity can be verified

	    later. This enable the detection of loss, deletion or

	    other manipulation syslog data after network transfer

	    or archiving on storage media.

	    </ul>

	    <br>

	    Martin Schuette is a student of computer science in

	    Potsdam, Germany, and has been working as a part-time

	    system administrator for BSD servers since 2004.

	    <br>

	    In 2007 Martin Schuette already gave a talk on Syslog

	    at the Chemnitze Linux-Tage

	    (http://chemnitzer.linux-tage.de/2007/vortraege/detail.html?idx=547

	    in german; for a newer english version see these slides

	    for a seminar talk:

	    <title>EuroBSDCon 2008 - Aggelos Economopoulos - An MP-capable network stack for DragonFlyBSD with minimal use of locks</title>

	    <desc>

		Given the modern trend towards multi-core shared

		memory multiprocessors, it is inconceivable for

		production OS kernels not to be reentrant. The

		typical approach for allowing multiple execution

		contexts to simultaneously execute in kernel mode

		has been to use fine-grained locking for synchronising

		access to shared resources. While this technique

		has been proven efficient, empirical evidence

		suggests that the resulting locking rules tend to

		be cumbersome even for the experienced kernel

		programmer, leading to bugs that are hard to diagnose.

		Moreover, scaling to more processors requires

		extensive use of locks, which may impose unnecessary

		locking overhead for small scale multiprocessor

		systems. This talk will describe the typical approach

		and then discuss the alternative approach taken in

		the DragonFlyBSD network stack. We will give an

		overview of the various protocol threads employed

		for network I/O processing and the common-case code

		paths for packet reception and transmission.

		Additionally, we'll need to make a passing reference

		to DragonFlyBSD's message passing model. This should

		establish a baseline, allowing us to focus on the

		recent work by the author to eliminate use of the

		Big Giant Lock in the performance-critical paths

		for the TCP and UDP protocols. The decision to

		constrain this work on the two by far most widely-used

		transport protocols was made in order to (a) limit

		the amount of work necessary and (b) explore the

		effectiveness of the approach on the cases that

		matter at this point in time.

	    <title>EuroBSDCon 2008 - Michael Dexter - Zen and the Art of Multiplicity Maintenance: An applied survey of BSD-licensed multiplicity strategies from chroot to mult</title>

	    <desc><![CDATA[

		Many BSD-licensed strategies of various levels of

		maturity exist to implement multiplicity, herein

		defined as the introduction of plurality to

		traditionally singular computing environments via

		isolation, virtualization, or other method. For

		example, the chroot utility introduces an additional

		isolated root execution environment within that of

		the host; or an emulator provides highly-isolated

		virtual systems that can run complete native or

		foreign operating systems. Motivations for multiplicity

		vary, but a demonstrable desire exists for users

		to obtain root or run a foreign binary or operating

		system. We propose a hands-on survey of portable

		and integrated BSD-licensed multiplicity strategies

		applicable to the FreeBSD, OpenBSD, DragonFlyBSD

		and NetBSD operating systems on the i386 architecture.

		We will also address three oft-coupled disciplines:

		software storage devices, the installation of

		operating system and userlands in multiplicity

		environments plus the management of select multiplicity

		environments. Finally we will comment on each

		strategies potential limits of isolation, compatibility,

		independence and potential overhead in comparison

		to traditional systems. Keywords: multiplicity,

		virtualization, chroot, jail, hypervisor, xen,

		compat.

		BSD-licensed multiplicity strategies for over five

		years. He is the Program Manager at the BSD Fund

		and Project Manager of the BSD.lv Project.

	    <title>EuroBSDCon 2008 - Nick Barkas - Dynamic memory allocation for dirhash in UFS2</title>

	    <desc><![CDATA[

		Hello My name is Nick Barkas. I'm a master's student

		studying scientific computing at Kungliga Tekniska

		hgskolan (KTH) in Stockholm, Sweden. I have just

		begun work on a Google Summer of Code project with

		FreeBSD: Dynamic memory allocation for dirhash in

		UFS2  . I would like to present my results from

		this project at EuroBSDCon this year. This project

		is very much a work in progress now so it is a bit

		difficult to summarize what I would ultimately

		present. I will try to describe an outline, though.

		First I will give background information on dirhash:

		an explanation of the directory data structure in

		UFS2, how directory lookups in this structure

		necessitate a linear search, and how dirhash speeds

		these lookups up without having to change anything

		about the directory data structure. Next I will

		explain the current limitation that dirhash's maximum

		memory use must be manually specified by administrators,

		or left at a small conservative default of 2MB. I

		will explain some different methods I will have

		explored to try and make this maximum memory limit

		dynamically increase and decrease as the system has

		more or less free memory, and which method I will

		have ultimately settled on and implemented. Then

		I'll present some test results of performance of

		operations on very large directories with and without

		dynamic memory allocation enabled for dirhash. Next

		I will talk about how speed gains from dirhash are

		limited by the fact that the hash tables exist only

		in memory and must be recreated after each system

		boot, as big directories are scanned for the first

		time, or even have to be recreated for a directory

		that has not been scanned in some time if its dirhash

		has been discarded to free memory. These problems

		can be eliminated by using an on-disk index for

		directory entries. I will talk about some of the

		challenges of implementing on-disk indexing, such

		as remaining backwards compatible with older versions

		of UFS2 and interoperating properly with softupdates.

		Then, if my SoC project has permitted me time to

		work on this aspect of it, I will explain some

		possible methods for adding directory indexing to

		UFS2 that meets these challenges, and which of those

		ideas I will have implemented. Finally I will present

		results of some benchmarks on this filesystem with

		indices, and compare to performance with dirhash,

		and with no indices or dirhashes.

		<br>

		Keywords: dirhash, ufs2, filesystems, performance tuning

	    <title>EuroBSDCon 2008 - Hauke Fath - Managing BSD desktop clients - Fencing in the herd</title>

	    <desc><![CDATA[

		The members of the BSD family have traditionally

		prospered off the desktop, as operating systems on

		servers and embedded systems. The advent of MacOS

		X has marked a change, and moved the desktop more

		into focus. Modern desktop systems create a richer

		software landscape, with more diverse requirements,

		than their server counterparts. User demands,

		software package interdependencies and frequent

		security issues result in a change rate that can

		put a considerable load on the admin staff. Without

		central management tools, previously identical

		installations diverge quickly. This paper looks at

		concepts and strategies for managing tens to hundreds

		of modern, Unix-like desktop clients. The available

		management tools range from simple, image-based

		software distribution, mainly used for setting up

		uniform clients, to "intelligent" rule-based engines

		capable of search-and-replace operations on

		configuration files. We will briefly compare their

		properties and limitations, then take a closer look

		at Radmind, a suite for file level administration

		of Unix clients. Radmind has been in use in the

		Institute of Telecommunication at Technische

		Universitt Darmstadt for over three years, managing

		NetBSD and Debian Linux clients in the labs as well

		as faculty members' machines. We will explore the

		Radmind suite's underlying concepts and functionality.

		In order to see how the concept holds up, we will

		discuss real-world scenarios from the system

		life-cycle of Installation, configuration changes,

		security updates, component updates, and system

		upgrades.

		<br>

		Hauke Fath works as a systems administrator for the

		Institut fr Nachrichtentechnik (telecommunication)

		at Technische Universitt Darmstadt. He has been

		using NetBSD since 1994, when he first booted a

		NetBSD 1.0A kernel on a Macintosh SE/30. NetBSD

		helped shaping his career by causing a slow drift

		from application programmer's work towards systems

		and network administration. Hauke Fath holds a MS

		in Physics and became a NetBSD developer in late

		2006.

		This paper discusses the NetBSD Power Management

		The outlined changes allow NetBSD to support essential

		functions like suspend-to-RAM on most post-Y2K X86

		machines. They are also the fundation for intelligent

		handling of device activity by enabling devices

		on-demand. This work is still progressing. Many of

		Operating System kernels available. For various

		reasons it is also assumed that NetBSD only runs

		well on older hardware. In the summer of 2006 Charles

		Hannum, one of the founders of NetBSD, left with a

		long mail mentioning as important issues the lack

		of proper power management and suspendto- RAM

		support. One year later, Jared D. McNeill posted a

	    <desc>

		The Aerospace Corporation operates a federally

		funded research and development center in support

		of national-security, civil and commercial space

		programs. Many of our 2400+ engineers use a variety

		of computing technologies to support their work.

		Applications range from small models which are

		easily handled by desktops to parameter studies

		involving thousands of cpu hours and traditional,

		large scale parallel codes such as computational

		fluid dynamics and molecular modeling applications.

		Our primary resources used to support these large

		applications are computing clusters. Our current

		primary cluster, the Fellowship cluster consists

		of 352 dual-processor nodes with a total of 14xx

		cores. Two additional clusters, beginning at 150

		dual-processor nodes each are being constructed to

		augment Fellowship. As in In any multiuser computing

		environment with limited resources, user competition

		for resources is a significant burden. Users want

		everything they need to do their job, right now.

		Unfortunately, other users may need those resources

		at the same time. Thus, systems to arbitrate this

		resource contention are necessary. On Fellowship

		we have deployed the Sun Grid Engine scheduler which

		scheduled batch jobs across the nodes. In the next

		section we discuss the performance problems that

		can occur when sharing resources in a high performance

		computing cluster. We then discuss range of

		possibilities to address these problems. We then

		explain the solutions we are investigating and

		describe our experiments with them. We then conclude

		with a discussion of future work.

		users to log in to a secure server and get their

		customized client, certificates and configuration.

		The NSIS installer is used to generate the customized

		windows installers. Similar packages are generated

		for the various Unix based clients. Additional

		WWW/PHP based tools, have been developed to monitor

		and log usage of the service, using standard graphs,

		alarms for excessive use and a certificate revocation

		mechanism. The system has been integrated into the

		local identity management system (Kerberos/LDAP)

		in order to authorize and authenticate users upon

		initiation and per session usage. All code is Open

		Source and freely available.

	    <title>EuroBSDCon 2008 - George Neville-Neil - Four years of summer of code</title>

	    <desc>

		The Google Summer of Code is a program designed to

		provide students with real world experience

		contributing to open source projects during the

		summer break in university studies. Each year Google

		selects a number of open source projects to act as

		mentoring organizations. Students are invited to

		submit project proposals for the open source projects

		that are most interesting to them. FreeBSD was one

		of the projects selected to participate in the

		inaugural Summer of Code in 2005 and we have

		participated each year since then. Over the past 4

		years a total of 79 students have participated in

		the program and it has become a very significant

		source of new committers to FreeBSD. This talk will

		examine in detail the selection criteria for projects,

		the impact that successful projects have had, and

		some suggestions for how we can better leverage

		this program in the future.

	    <title>EuroBSDCon 2008 - Anttii Kantee - Converting kernel file systems to services</title>

	    <desc><![CDATA[

		ABSD/UNIX operating system is traditionally split

		into two pieces: the kernel and userspace. Historically

		the reasons for this were clear: the UNIX kernel

		was a simple entity. However, over time the kernel

		has grown more and more complex. Currently, most

		of the same functionality is available both in

		userspace and the kernel, but under different names.

		Examples include synchronization routines and

		threading support. For instance, to lock a mutex

		in the NetBSD kernel, the call is mutex_enter(),

		while in userspace the routine which does exactly

		the same thing is known as pthread_mutex_enter().

		Taking another classic example, a BSD style OS has

		malloc()/free() available both in userspace and the

		kernel, but with different linkage (the kernel

		malloc interface is currently being widely deprecated,

		though). This imposes a completely arbitrary division

		between the kernel and userspace. Most functionality

		provided by an opearating system should be treated

		as a service instead of explicitly pinning it down

		as a userspace daemon or a kernel driver. Currently,

		due to the arbitrarily difference in programming

		interface names, functionality must be explicitly

		ported between the kernel and userspace if it is

		to run in one or the other environment. By unifying

		the environments where possible, the arbitrary

		division is weakened and porting between these

		environments becomes simpler.

		<br>

		Antti Kantee has been a NetBSD developer for many

		many moons. He has managed to work on quite a few

		bits and pieces of a BSD system: userland utilities,

		the pkgsrc packaging system, networking, virtual

		memory, device drivers, hardware support and file

		systems.

	    <title>EuroBSDCon 2008 - Matthieu Herrb - Input handling in wscons and X.Org</title>

	    <desc><![CDATA[

		This talk will present the different layers that

		handle input, from the key that gets pressed or the

		mouse motion to the applications, all the way through

		the kernel drivers, X drivers and libraries, in the

		case of the OpenBSD/NetBSD wscons driver and the

		current and future X.Org server. It will cover stuff

		like keyboard mappings, touch-screen calibration,

		multi-pointer X or input coordinates transformations.

		It will show some problems of current implementations

		and try to show how current evolutions can solve

		them.

		<br>

		Matthieu Herrb is maintaing X on OpenBSD. I've been

		using X on various systems (SunOS, NetBSD, OpenBSD,

		Mac OS X,...) since 1989. He has been a member of

		the XFree86 Core Team for a short period in 2003

		and is now a member of the X.Org Foundation BoD.

		Matthieu Herrb works at LAAS a research laborarory

		of the French National Research Agency (CNRS) both

		on robotics and network security.
