Hardware Performance Monitoring Counters (video)


George Neville-Neil: Hardware Performance Monitoring Counters on non-X86 Architectures

AsiaBSDCon 2010 paper session.

Abstract:

Hardware Performance Monitoring Counters provide programmers and systems integrators with the ability to gather accurate, low level, information about the performance of their code, both at the user and kernel levels. Until recently these counters were only available on Intel and AMD chips but they have now been made available on alternate, embedded, architectures such as MIPS and ARM.

This paper discusses the motivation, design and implementation of counters using the hwpmc(4) driver in the FreeBSD operating system with an eye towards easing future porting efforts.

BSD in the routing industry (video)


Massimiliano Stucchi: BSD in the routing industry

AsiaBSDCon 2010 paper session.

Abstract:

The BSD family has always been very well known for its robust network stack, hence it has been widely used in many different fields and applications. In the ISP market, though, the situation is totally different, and solutions employing *BSD operating systems are often discarded in favour of proprietary solutions.

In this talk we will discuss the different possibilities offered by the BSD operating systems family in terms of networking tools and practices, compared to proprietary solutions offered by companies such as Cisco and Juniper, detailing the differences between them and highlighting the major points and drawbacks of each of them, up to a cost comparison in real field applications.

Real field applications will be introduced via explanation of the solutions created using BSD-based routing software in the real industry running in two different environments, an ISP spanning Europe and another one offering WISP services.

We will also delve into the experience in running a FreeBSD-/OpenBSD- and OpenBGPd-based route server at MINAP, the MIlanNeutralAccessPoint, describing success stories and guiding the audience into a comparison with the other route servers running at the same IX, powered by Linux and Bird/Quagga.

Quiet Computing with BSD (video)


Constantine A. Murenin: Quiet Computing with BSD

AsiaBSDCon 2010 paper session.

Abstract:

Quiet Computing with BSD (Programming system hardware monitors for quiet computing)

In this talk, we will present an overview of the features and common problems of microprocessor system hardware monitors as they relate to the topic of silent computing. In a nutshell, the topic of programmable fan control will be explored. A live demonstration of the fan-controlling prototype might be possible.

Silent computing is an important subject as its practice reduces the amount of unnecessary stress and improves the motivation of the workforce, at home and in the office.

Attendees will gain knowledge on how to effectively programme the chips to minimise fan noise without impeding reliability or causing any system failures, as well as some basic principles regarding the practice of quiet computing.

A patch for programming the most popular chips (like those from Winbond) is already publicly available for the OpenBSD operating system, although the talk itself will be more specific to the microprocessor system hardware monitors themselves, as opposed to any specific interfacing with thereof in modern operating systems like OpenBSD, NetBSD, DragonFly BSD and FreeBSD.

Wireless Mesh Networks under FreeBSD (video)


Rui Paulo: Wireless Mesh Networks under FreeBSD

AsiaBSDCon 2010 paper session.

Abstract:

With the advent of low cost wireless chipsets, wireless mesh networks became much more attractive for both companies, governments, and the general consumer. Wireless mesh networks are being used extensively since the popularization of the 802.11 wireless technologies, but usually they worked with the help of layer 3 routing technologies.

Since 802.11 didn’t provide any kind of support for wireless mesh networks, in 2004, IEEE created the Task Group s (TGs) to develop a new amendment to 802.11 which would define the operation of a wireless mesh network using existing 802.11 hardware and having a routing protocol work at layer 2. Later, the amendment also included provisions for mesh authentication, encryption, link management, bridging mesh networks with other types of networks, and channel reservation.

This paper will talk about the FreeBSD implementation of 802.11s that’s available in version 8.0 and beyond. This work was sponsored by The FreeBSD Foundation.

Porting HPC Tools to FreeBSD (video)


AsiaBSDCon 2010 paper session.

Abstract:

Since 2001 we have used FreeBSD as a high performance computing (HPC) cluster operating system. In the process we have ported a number of HPC tools including Ganglia, Globus, Open MPI, and Sun Grid Engine. In this talk we will discuss the process of porting these types of applications and issues encountered while maintaining these tools. In addition to generally issues of porting code from one Unix-like operating system to another, there are several type of porting common to many HPC infrastructure codes which we will explore. Beyond porting, we will discuss how the ports collection aids our use of HPC applications and ways we think overall integration could be improved.

PC-SYSINSTALL – A new system installer backend for PC-BSD and FreeBSD

This presentation was done by Kris Moore, founder of the PC-BSD Project at AsiaBSDCon 2010.

Abstract: The sysinstall tool has been the default system installer for FreeBSD for more than a decade now. While is it has proven itself to be reliable and resilient over the years, it doesn’t support many of the new features that FreeBSD offers, as well as being un-intuitive for desktop users, who expect an easy to use graphical front-end to perform their installation. To solve these two problems the “pc-sysinstall” backend was created and now is in usage for PC-BSD 8.0. This new installer backend provides much of the same functionality as sysinstall, while offering many new features such as support for ZFS, Encryption, mirroring, scriptable installs and the ability to work with different front-ends, such as a QT based GUI. The backend also supports installing regular FreeBSD, which allows server administrators to quickly perform an installation using the new disk features it offers.

MaheshaBSD: A Live CD Project From The Lake Mansarovar

MaheshaBSD is the name for a Live CD project. Why Mahesha? What does it mean? Mahesha is one of the 1008 names of Lord Shiva – Supreme God of the universe who stands above all gods. This name was chosen because Shiva’s weapon is the same as the FreeBSD’s one – the trident. There is yet another important correlation – supremacy of the BSD code, which (as many IT professionals believe) stands supreme above all operating systems. The connection of Lord Shiva and BSD is therefore logical.

OpenBSD as a Primary Domain Controller

Once a Windows-based network grows beyond around a dozen computers, setting up a Primary Domain Controller to simplify and centralize the management of users, computers and network resources becomes a must. But does the Domain Controller necessarily have to be a Windows machine, thus meaning the end of our project of a completly OpenBSD-based server network?
Of course not! Once again, OpenBSD comes to our rescue and, with the help of a few additional pieces of software, it will turn into a full-blown, secure and reliable Domain Controller.

FreeBSD MySQL Clustering How-to

The PHP, MySQL and Apache stack is a very popular implementation on standalone BSD servers but in demanding high availability [HA] environments the twin spectres of redundancy and fail-over rear their heads. In these scenarios, it is essential to eliminate the single point of failure which is the enemy of 100% uptime.

BSD FILE SHARING – Part 3. FTP

Last time I wrote on SAMBA on different BSD’s. This time I am going to dedicate the article of the series to FTP. Some people do not know that the FTP protocol is the true BSD heritage, as it originated in the 1970′s at Berkeley University, so it is the right thing to dedicate it some space in the BSDMag anyway.

Exploring HAMMER

One of DragonFly’s features is a new file system, called HAMMER. HAMMER has, to quote from the man page, instant crash recovery, large file systems spanning multiple volumes, data integrity checking, fine-grained history retention, mirroring capability, and pseudo file systems HAMMER is available by default on DragonFly BSD.

Embedded OpenBSD

Unix-like operating systems aren’t picky at all. Despite the extreme physical conditions, they can take root on those old computers where most (proprietary) operating systems risk extinction and help them, after years of faithful service, to start new lives as firewalls, routers, proxies …
But sometimes this is not enough: servers must be reliable and old computers are (guess what?) … Old, and this increases their risk of disease. That’s why embedded systems are a great option: they are (relatively) inexpensive, silent, small , reliable … What else could you need? Ok, you have to learn to cohabit with very basic hardware, but the right OS, with the right configuration, will wallow in it!

Making Sense of Data Management on Intelligent Devices

The demand for embedded devices is growing rapidly, and there is a clear need for development of advanced software to deliver new features on limited hardware. Data management is a critical component in these new software systems. Embedded databases are used by portable media players to store information about music and video, GPS vehicle tracking systems to store map data, and monitoring systems to log information. These and other leading-edge industries have learned the importance of managing data reliably with a relational embedded data management system.

BSD in the Industry

After several years of slavery with windows based programs, many programs related with Industry or Engineering are opening the doors to the new trends of UNIX like OS. This is a natural evolution because as the Economy crisis strikes on whole World, the IT infrastructures are also under pressure to decrease at maximum the overall cost.
