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.

Audio presentations: 1 pfSense and 2 BSD for Linux Users

Dru Lavigne has uploaded the audio file of her presentation at SCALE 2010 talk on BSD for Linux Users is now available in mp3 format. Slides are available as PDF

She also mentioned an mp3 of a NYCBUG session on PFSense II, Rocking The Datacenter.

pfSense is a free, open source customized distribution of FreeBSD tailored for use as a firewall and router. In addition to being a powerful, flexible firewalling and routing platform, it includes a long list of related features and a package system allowing further expandability without adding bloat and potential security vulnerabilities to the base distribution.

AsiaBSDCon 2010

AsiaBSDCon 2010 will be held from 11-14 March in Tokyo

AsiaBSDCon is a conference for users and developers on BSD based systems. The next conference will be held in Tokyo, in 11-14 March, 2010. The conference is for anyone developing, deploying and using systems based on FreeBSD, NetBSD, OpenBSD, DragonFlyBSD, Darwin and MacOS X. AsiaBSDCon is a technical conference and aims to collect the best technical papers and presentations available to ensure that the latest developments in our open source community are shared with the widest possible audience.
