Spikey Appendix¶
Setting up SSH keys on UHEI cluster for github.com¶
To create a key pair please follow the guide provided by github.com.
The configuration file for the ssh connection is located in ~/.ssh/config
.
For example:
$ cat .ssh/config
Host github.com
IdentityFile /wang/users/USERNAME/.ssh/my_github.com.id_rsa
The Host github.com
describes the ssh
connection target, and the following line
configures the private key location which will be used for this target host.
To connect via ssh, use the tsocks
tool which routes the TCP connection via a local SOCKS proxy, e.g.:
$ tsocks git clone git@github.com:USERNAME/PROJECT.git
Setup software¶
Preparing the operating system¶
We consider the newest stable Debian operating system as reference system.
The following additional software packages are required for building the software of the Spikey system:
sudo apt-get install libboost-all-dev libusb-1.0-0-dev liblog4cxx10-dev libqt4-dev libgtest-dev libgsl0-dev python-nose
And for experiment execution:
sudo apt-get install python-numpy python-scipy python-matplotlib
Installing hardware drivers¶
The software for the Spikey neuromorphic system is managed by a git repository that can be downloaded as follows:
git clone https://github.com/electronicvisions/spikey_demo.git
To install the software follow the instructions in the README.md
file.
Note that a fork of the official PyNN project is used that builds on PyNN version 0.6.
Allow access to USB device¶
To access the Spikey system via USB, add your user to the plugdev
UNIX group, to which Spikey devices are assigned to.
Note that you will need root privileges for adding users to a UNIX group.
Add your user to
plugdev
group:sudo usermod -aG plugdev USERNAME
(replace USERNAME)Assign Spikey systems to
plugdev
group (creates audev
config file):sudo sh vmodule/nosudo
Restart
udev
daemon:service udev restart
and (re-)plug-in the Spikey USB device.
Run experiments¶
Set environment variables (has to be done only once for each environment):
. bin/env.sh
Run PyNN description of a network:
cd networks
python example.py
Miscellaneous¶
If multiple chips are connected to a single host computer, use environment variables to select the chip:
MY_STAGE1_STATION=stationXXX
Replace XXX with the chip you want to use (e.g. 500).
