Installing

calibration

Create conda environment with Python 3.5 or later:

conda create -n {env_name} python=3.6

Activate conda environment:

conda activate {env_name}
conda install -c conda-forge openmpi 
pip install -e .

How to use at XFEL

Use of notebooks

• Get the repository in your workspace, either on online or Maxwell cluster:

    user@machine git clone https://git.xfel.eu/gitlab/dataAnalysis/calibration-services.git
  

  Notebooks are available in the folder calibration-services/notebooks

Running a jupyter server on online cluster

• Via FastX client

  Open a terminal and type the following commands

    user@max-display: ssh exflgateway
    ssh exflonc<NN>  #NN = 12 for eg.
    module load exfel calibration-services
    jupyter-notebook --port 8008 --no-browser
  

  This will start a jupyter server on online cluster and a link will be provided that you can copy.

  Now open another terminal and do the port forwarding

    user@max-display: ssh -L 8008:localhost:8008 exflgateway -t ssh -L 8008:localhost:8008 exflonc<NN>
  

  Open your regular browser and paste the link that you copied before the last step. Provided you have cloned the repository as shown in first step, the calibration-services folder will be visible in the jupyter notebook.

• Via local computer

  Open a terminal and type the following commands

    user@localmachine$ ssh user@bastion.desy.de
    ssh exflgateway
    ssh exflonc<NN>
    module load exfel calibration-services
    jupyter-notebook --port 8008 --no-browser --ip "*"
  

  Now open another terminal and do the port forwarding

    user@localmachine: ssh -L 8008:localhost:8008 user@bastion.desy.de -t ssh -L 8008:exflonc<NN>:8008 exflgateway
  

  Open your regular browser and paste the link that you copied before the last step.

• From the hutch control room computers

  Open a terminal and type the following commands

    ssh exflonc<NN>
    module load exfel calibration-services
    jupyter-notebook --port 8008 --no-browser
  

  Open another terminal and do the port forwarding

    ssh -L 8008:localhost:8008 exflonc<NN>
  

  Open your regular browser and paste the link that you copied before the last step.

Running notebooks on Maxwell cluster

On Maxwell cluster:

module load exfel calibration-services

Preferred way is to use jupyterhub instance running on https://max-jhub.desy.de/hub/login

Which jupyter kernel to use

Doing module load exfel calibration-services once, a jupyter kernel calibration-services-kernel will be created that can be used in jupyter notebooks.
