Xen Virtualization and Linux Clustering, Part 2

Filed under
HowTos

We ended last time after configuring our first unprivileged Xen domain. In this article, we complete our cluster and then test it using an open-source parallel ray tracer. The first thing we need to do is create additional slave nodes to be used with the cluster. So, let's get down to business.

Creating Additional Unprivileged Domains

Once you have created and configured an unprivileged domain using the instructions from the previous section, you easily can duplicate this domain as described below. Start by making a backup image of the Debian_Slave1_Root filesystem. You only need to do this step once. Note that the tar command probably will take a few minutes to complete, as it is archiving an entire filesystem.

OSS Leftovers: Harvard University Survey, ASF at 18 Years, Heiko Tietze at LibreOffice

  • Survey seeks to discover the motivations behind open source contributions
    Peer production is one of three fundamental ways to organize human economic activity, along with markets and firms. Yet, although it underlies billions of dollars in open source software production, it is the least understood. Participants in open source are not organized in firms, where they would work under the supervision of managers and earn a salary, nor are they individuals in a market, responding to price signals. The economics of peer production is an interesting area of study that raises many important questions regarding the incentives behind voluntary participation, the efficiency of production, the tools and models that can quantify and explain how the process works, and so forth. My doctoral research at Harvard University considered incentives issues that arise in a software economy. In particular, my work used principles from market design and mechanism design to address problems, such as how to incentivize high-quality submissions to address bugs or features, and how to elicit truthful prediction of task completion time.
