Setting up the cluster

This entry is part 3 of 5 in the series Raspberry Cluster

Since the case is pretty much complete now, it is time to take a look at the software. I finally decided to run Raspian on the PIs and Lubuntu on the Banana Pi. While there may be other (maybe even more suitable) OSes available I think is the best starting point for my project. The Banana Pi is equipped with Lubuntu.

After booting the Banana Pi I switched to the German keyboard layout (unfortunately the corresponding GUI is horrible). Afterwards the usual apt-get update and apt-get upgrade took care of software updates.

The next steps are the configuration of a static IP as well as the installation of the SSH demon and samba.

Banana Pi updating

EDIT

I just learnt about Bananian which is based on Debian 7. It does not provide a desktop environment, so a 2 GB SD card is said to be sufficient. Since I just want the Bananapi to act as samba server all the Lubuntu features are pretty irrelevant for me.

It also has a sshd running

Building a Raspberry Pi 2cluster

This entry is part 1 of 5 in the series Raspberry Cluster

Big Data, Hadoop, NumPy, R cluster computing etc. are pretty hot topics. To get my hands on them and get a deeper understanding I have decided to build my own cluster out of small Raspberry Pi 2 computers. I am not the first one to come up with this idea, you can find a few nice examples online.

I have decided to use five Raspberry Pi 2 and one Banana Pi in this cluster. The Banana Pi has the advantage of being equipped with a Serial ATA port, my plan is to use it to store the data the Raspberries are working on.

The general setup is the following:

  1. 5 x Raspberry Pi 2 from Pollin for 37.95 Euro each
  2. A TP-Link 8-Port Gigabit Switch for 20.99 Euro
  3. a 6-Port RAVpower USB power source (3 x 1.0 Amp, 3 x 2.4 Amp) for 17.99 Euro
  4. a couple of five micro USB cables for 12.99 Euro
  5. Identical 16 GB micro-SD cards from Sandisk, Class 10 for 10.99 each
  6. the Banana Pi (I got mine from notebooksbilliger.de for 33.89 Euro)
  7. a SATA Power/Data cable to connect a 2.5″ harddisk to the Banana Pi

So altogether I spent around 320 for the electronic parts, some other parts (like SD card and USB cable for the Banana Pi) I had in my stash.

In the next article of this series I’ll describe the case I am currently building out of Lego Technics parts…

Raspberry Pi unter Windows emulieren

Unter http://sourceforge.net/projects/rpiqemuwindows/ gibt es ein fertiges Emulator-Paket für den Raspberry Pi. Einfach entpacken und die run.bat ausführen. Läuft bei mir unter Windows 7 64-Bit sehr gut.

TeX Live auf Raspian

Vor zwei Tagen habe ich auf unter Raspian TeX Live 2012 installiert. Die Installation war recht einfach:

  1. Net Installer von tug.org herunterladen und entpacken
  2. Installation laufen lassen (am besten über Nacht)
  3. PATH Variable in der .bashrc erweitern (PATH=/usr/local/texlive/2012/bin/armel-linux:$PATH; export PATH
    )
  4. source ~/.bashrc ausführen, damit die PATH-Änderung aktiv ist

Erste Schritte mit Raspian

Ziemlich cool an Raspian ist das raspi-config Script, das man über sudo raspi-config aufruft. Änderungen von Locale, Tastaturlayout, etc. lassen sich hier über ein text-basiertes Menü eingeben. Und auch die Erweiterung des Speicherplatzes auf die gesamte SD Karte lässt sich hier erledigen.

Als SD Karte für Raspian nutze ich eine Class 10 von Transcend mit 16 GB (16 Euro bei Saturn), sollte für die ersten Schritte ausreichend sein.
