amturingpi project cancelled

Raspberry Pi 2B

It's official! the amturingpi project is cancelled!

After some more research I figured out a Beowulf cluster might be a nice research project, but it is not useful for the goal I had in mind.

I'm currently using my Raspberry Pi 2B as a "regular desktop computer", running (a modified version of) Ubuntu MATE (Linux) for Raspberry Pi2.

Thus I bought/used the following additional hardware.

  • 2 additional Raspberry Pi 2B boards;
  • 1 HDMI cable;
  • 1 HDMI to DVI-D converter;
  • 1 Wireless keyboard and mouse set;
  • 1 Euro to USB adapter;
  • 1 USB 4 port HUB;
  • 4 USB to Micro USB cables;
  • 1 Ethernet Switch;
  • 4 CAT6 Twisted pair cables with RJ-45 connectors;
  • 1 Official Raspberry Pi power supply;
  • 1 Raspberry Pi Case (black);
  • 1 32 GB MicroSD card (for experimental Operating Systems);
  • 1 USB Wireless adapter (owned already);
  • 1 1.5 TB USB HDD (owned already).

The next research project is to use the RPI as a client for a Linux Terminal Server. But it doesn't make sense to document this myself, because it already is documented at the Project Homepage.

First experiences with the Raspberry PI 2B

I received my first Raspberry PI 2B as a birthday present from my sister in law Marij and brother Michel and haven't left it untouched ever since!

However in contrast to the majority of Raspberry Pi Enthusiasts, I am a seasoned Linux user (for 15 years), meaning my first steps with the Raspberry Pi 2B where a piece of cake, hardly a adventure ;-)

The first distribution I tried was Ubuntu MATE, which required only a single tweak.

I edited the /boot/config.txt file

sudo nano /boot/config.txt

to disable the "overscan" and get the correct screen resolution, by "un-commenting" (removing the # character) in line 10 to:

disable_overscan=1
 

Saving the edited file by pressing:

Ctrl X and Y


Then I rebooted, which solved the annoyance of an incorrect screen resolution. 

After two days, I gave Rasbian a shot and reverted back to Ubuntu MATE, because the former is too minimalistic for my likings.

The plan is to buy another MicroSD card, for "distro hopping" and keep Ubuntu MATE installed on the main MicroSD card, which I also got from Marij and Michel.

Temporarily I'm using the Raspberry Pi 2B in my living room, because of the lack of a decent power supply and HDMI to DVI-D converter, I mostly control the MU (Master Unit) via ssh and VNC.

The plan is to buy the required hardware next week and place the nano cluster computer in my bedroom, with a dedicated flat screen monitor, 2 TB USB HDD (which I own already) and a wireless keyboard and mouse combination.

Needless to say I am extremely excited by the Raspberry Pi 2B and a nano cluster is not the only application I have for the cute little, yet powerful British computer!

Great news for the amturingpi project

There is some great news for the #amturingpi project. First of all, I will get the first Raspberry PI 2 B and a 32GB Micro SDcard for my birthday, as a present by brother Michel and sister in law Marij. This will become the "master".
Second, I have decided to go with Ubuntu MATE for the Raspberry PI 2 for the base distribution.

Third, I figured out that PXE doesn't work on arm SOC's and found a work around in Das U-boot.

Looking forward to start the first experiments.

Introducing the A.M TuringPi (nano) computer cluster (update)

The Logo (so far).

Introduction.

 

Ladies and gentlemen, I am delighted to introduce my next pet project, the A.M TuringPi computer cluster, based on Raspberry Pi 2 boards, using a Linux based Operating System, taking advantage of its scalability and outstanding PXE support.

The project is named in honour of Alan Turing

Goal.

 

The goal is to create a "poor man's" 8 node (nano) computer cluster, who everyone - with average computer knowledge - is able to deploy. With the introduction of the powerful, yet energy efficient and cheap Raspberry Pi2, deploying your very own computer cluster, became a reasonable and valid option.

Base System (update April 2 2015).

 

The base system will be a 3 node system for the first experiments, I will add nodes from time to time.

Implementation.

 

The A.M TuringPi computer cluster will consist of a MU (Master Unit), while all other units are called nodes.

The MU will have a keyboard, mouse, screen attached and will also provide boot- and disk services. All other nodes will merely provide CPU power and RAM.

Documentation.

 

Since the A.M TuringPi project is probably too technical, to post on general Social Media, I will keep you up to date with the progress on osg33x.
