Raspberry Pi Cluster

Installing Root

• sudo apt-get install git dpkg-dev make g++ gcc binutils libx11-dev libxpm-dev libxft-dev libxext-dev python-dev gfortran
• tar -zxvf xxxx.tar.gz

In order to use pyRoot with Raspbian you need to specify where the libx11, libxpm etc files are. It is the .so you are looking for. A good method to search for these is to type:

• find / -name libx11.so -print

Then do

• ./configure linuxarm --enable-python --with-x11-libdir=/usr/share/doc/ --with-xmp-libdir=/usr/share/doc/

The path to x11 and xmp will be the same, and you may need one or two more for xeft (or something, look at the error messages). Finally,

• make
• make install

Root and pyRoot should now work. There are tests you can run in the Examples directory.

Setting up wireless with USB

• sudo nano /etc/network/interfaces

auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

Then

• sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

 
network={
   ssid="eduroam"
   proto=RSN
   key_mgmt=WPA-EAP
   pairwise=CCMP
   auth_alg=OPEN
   eap=PEAP
   identity="usrname@wf.uct.ac.za"
   password="password"
}=

Logging in automatically

• sudo nano /etc/inittab

Comment out the line

1:2345:respawn:/sbin/getty 115200 tty1

then below it add:

1:2345:respawn:/bin/login -f pi tty1 </dev/tty1 >/dev/tty1 2>&1

mpi4py

• sudo apt-get install python-pip
• pip install mpi4py
