Installing and Configuring Raspbian
- Follow the software configuration steps shown in this video and burn the image file to an SD card for each computer in your cluster.
- For each Raspberry Pi in your cluster, insert an imaged SD card, connect them all to the same router or switch, and then connect a power source to each one.

Installing and Configuring Raspbian
- Download the Raspbian Image from here.
- Burn the Raspbian Image to your SD Card
  - If you have Windows, you can follow these instructions.
  - If you have a Mac, you can follow these instructions.
- Once the image is burned to your SD Card, but it into the Raspberry Pi and boot it up with a Keyboard, Mouse, Monitor and Internet attached.
- Upon first boot, you should see the Rasbperry Pi Configuration screen (otherwise type “sudo raspbi-config“. Here’s the options we’ll need to configure
[tabby title=”Terminal Commands”]

Installing MPICH
- MPICH is software that allows for multi-processing communication between computers.
- To install it on your Raspberry Pi, first make sure you have a valid Internet connection going to the Pi. Then follow these Terminal Commands
  - sudo apt-get update
  - mkdir mpich2
  - cd ~/mpich2
  - wget http://www.mpich.org/static/downloads/3.1/mpich-3.1.tar.gz
  - tar xfz mpich-3.1.tar.gz
  - sudo mkdir /home/rpimpi/
  - sudo mkdir /home/rpimpi/mpi-install
  - mkdir /home/pi/mpi-build
  - cd /home/pi/mpi-build
  - sudo apt-get install gfortran
  - sudo /home/pi/mpich2/mpich-3.1/configure -prefix=/home/rpimpi/mpi-install
  - sudo make
  - sudo make install
  - nano .bashrc
    
    PATH=$PATH:/home/rpimpi/mpi-install/bin
  - sudo reboot
  - mpiexec -n 1 hostname
- These commands will download and install MPICH, as well as add it as a path to your BASHRC boot file. The last command runs a test to see if it works. If the last command returns “Pi01”, then you did everything successfully.
Installing MPI4PY
- As it is, MPICH can run C and Fortran programs. But since the Raspberry Pi has the Python coding environment pre-installed, it would be easiest to install a Python to MPI interpreter. Here’s the commands to do that:
  - sudo aptitude install python-dev
  - wget https://mpi4py.googlecode.com/files/mpi4py-1.3.1.tar.gz
  - tar -zxf mpi4py-1.3.1
  - cd mpi4py-1.3.1
  - python setup.py build
  - python setup.py install
  - export PYTHONPATH=/home/pi/mpi4py-1.3.1
  - mpiexec -n 5 python demo/helloworld.py
