Distributed Java, Fortran, and ARM to X86 Cross Compilation

A very cool and strange thing (for me at least) has happened. Having spent a great deal of time digging through my Google analytic reports, I can say with certainty that my personal site traffic is on the rise. What’s most interesting to me is that a good portion of that new readership linked into my site from my corporate blog. Even more interesting, our corporate blog over at www.discursivelabs.com has far eclipsed the readership of my personal blog here at www.hunterdavis.com. As such, I thought I’d share the link to my newest article.

In the fifth article in our ongoing series on low power compilation clusters, things are really starting to get interesting. I run you through a distributed Java, Fortran, and ARM->X86-64 compilation using an updated set of scripts we created in our previous articles, as well as post an update on the real-world Pogoplug compilation cluster (hint: twice as fast).

Writing Your Own Distributed Compilation System

As the title implies in our latest article over at Discursive Labs we walk you through the creation of a fully distributed compilation system (i.e. a fully federated system not based on DistCC, Sun’s DMAKE, or other existing distributed compilation tools). The scripts are available in the article and can be dropped into an existing compilation node or as a base for future development. While I have posted a few articles over at Discursive Labs since I last posted here, I thought this one in particular may be of interest to anyone wishing to make their own cluster for compilation or scientific computing. If you’re interested in cross-compiling, low power ARM clusters, virtual clusters or distributed computing and you’re not reading our continuing series then you should really catch up.

*UPDATE — These articles have been collected into the volume ‘Build Your Own Distributed Compilation Cluster’, read more at it’s information page here.

Using the ARM Based PogoPlug as an X86-64 Compilation Cluster – An Article Series

Are you looking for something new and interesting to run on your Pogoplug after reading that last article on emulators? Ever considered using it to compile software that runs natively on your X86-64 machine? Did you even know this was a possibility?

On our corporate blog over at Discursive Labs, I’ve posted up the first in a new article series about creating an ARM based X86-64 cross-compiling cluster. For the first in the article series, we run you through the basic configuration, compilation, and toolchain creation for ARM to X86-64 compilation. In future articles we’ll discuss issues involved in library cross-compilation, sorting through “dependency hell”, adding new compilation nodes, and the benefits of using a low-power compilation cluster in your build and CIS processes. We’ll walk you through a full cross-compile of one of our beta software products, and all of its prerequisite libraries in detail.

As always, if you’re interested in beta testing any of our upcoming software, send an email to beta@discursivelabs.com.

Jailbreaking a PS3 with Trackball Style (With Video)

After a particularly long (but rewarding) day of prototyping and contract hunting over at Discursive Labs, Mark and I weren’t quite ready to stop creating when the work day ended. Already having his trusty iron handy, and me with my parts (and MY AXE), we decided to unwind and relax by hacking something. Typical Wednesdays right? Anyway, after reading about how the PS3 homebrew scene is blowing up, we decided to see if we could build a PS3 jailbreak device with parts we had around our workbench. After finding an old ‘atari in a joystick’ TV game we had previously stuffed into a PS1 trackball, we had the spark of an idea. Read on for photos, video, a ridiculously scatterbrained photostream, and all around good times.
