Ipython notebook

IPython is an interactive Python environment. Coupled with the "notebook" module, it provides a rich web interface.

Launch a notebook

1. Connect to the cluster.
2. Load an environment :

   IPython notebook is available on the cluster in 2 environments : the custom build and CVMFS.

   • To load from CVMFS :

     See IceCube_software#CVMFS

   • To load from the custom build [deprecated] :

     source /software/sources/latestEnvironment.source

3. Launch a notebook to which you will later connect to from your laptop:

   ipython notebook --no-browser --pylab inline

   When launching the notebook, the system will create a dedicated server for you. It will be running on a specific port chosen by the notebook itself.

   The launcher reports this port in the following way:

   The IPython Notebook is running at: http://127.0.0.1:8888/

   • The port number [PORT_NUMBER] you need is the number coming after the colon (:).
   • The m-machine [M-MACHINE] is the machine where you launched the notebook.

4. Open a new terminal on your laptop and create a tunnel to the machine where you instantiated the notebook. Fill in the correct port number in the following command:

   ssh -L PORT_NUMBER:localhost:PORT_NUMBER M-MACHINE.iihe.ac.be

5. The tunneled notebook is available in your browser by opening the url : http://localhost:PORT_NUMBER
