A 5-node Raspberry Pi 3 cluster.

A 5-node Raspberry Pi 3 cluster.

Here’s my latest project. I realize I’m late getting on the bandwagon. I heard of the Raspberry Pi ahead of it’s initial introduction way back in February of 2012 but it didn’t pique my interest back then. This past summer, when my interest in SETI@home was again stirred up, I began looking into building a cheap computing cluster. I had long considered buying a set of cheap laptops for the project but none ever hit a reasonable price point for me. In particular, I always considered buying a bunch of Dell Latitude C400 units as I already had one that has been running almost non-stop since I bought it used in 2006. Unfortunately, a complete, working unit never was cheap enough for me.

With the news of the Pi 3 release, I started seeing articles of people building BOINC clusters with them. In particular, I found this YouTube video and it’s sequel, both by KF7IJZ which really illustrated how easy a Pi 3 cluster is to build. So I set about building one for myself.

I’m glad I decided on the Pis rather than the C400. With the two of them running side-by-side, I can see that the Pi is beating the C400 by quite a bit just by looking at the RAC. I’m up to five nodes right now but I intend to eventually have eight nodes and secure it all in some kind of case.

It’s been a long time since I updated the SETI@home Stats plugin. Seven years to be exact. I’ve updated a local copy and it seems to be working. The official SETI@home stats webpage had changed it’s format and the plugin’s regular expression matching needed to be updated to suit. You can see it working in my sidebar to the right.

Tonight I will try to get a new copy uploaded to the WordPress plugin repository. In the meantime, you can download a test version below.

SETI@home Stats 1.1.5

If you’re as addicted to SETI@home as I am you probably look for every chance to install the BOINC client on any computer possible. The default installation of the BOINC client requires administrative rights on Windows computers. If you’re working on a shared, supported or corporate computer you may not have administrative rights. Here’s the easy way around that.

  1. Download the BOINC client. (Version 6.6.36)
  2. Open a DOS box and change directory to the location of the BOINC client.
  3. Launch the BOINC client using the “/a” flag as in “boinc_6.6.36_windows_intelx86.exe /a”
  4. You will be prompted for a location to install the server portion of the application. Pick something.
  5. That’s it! Launch the client using “[install path]\program files\BOINC\boincmgr.exe”

There are other flags available for the install file. Use “/?” to see them all. For help with installing earlier versions of the BOINC client read this.
