sgespawner

DEPRECATED: it's recommended to use BatchSpawner and a custom options_form rather than this.

A Sun Grid Engine (SGE) Spawner for JupyterHub.

Designed to work with JupyterHub 0.7.2 but may work with more recent versions too.

Installation and usage

Install sgespawner into the same Python environment as JupyterHub using e.g. pip install /path/to/sge/clone
Make several changes to your main JupyterHub config file (which might be /etc/jupyterhub/jupyterhub.py):
1. Tell JupyterHub to use sgespawner to spawn single-user Jupyter servers (and remove any conflicting spawner_class lines):
```
c.JupyterHub.spawner_class = 'sgespawner.SGESpawner'
```
2. Ensure that the environment variables needed to submit SGE jobs (using qsub) are defined:
```
c.Spawner.sge_env = {'SGE_ROOT': '/usr/local/sge/live',
                     'SGE_CELL': 'default',
                     'SGE_CLUSTER_NAME': 'myclustername'}
```
3. Provide the path to the (Jinja2) template used to define the SGE batch jobs that start single-user Jupyter servers:
```
c.Spawner.sge_template = '/etc/jupyterhub/jupyterhub.sge.j2'
```
Tailor the Jinja2 template to meet your needs. The only requirements are the lines containing working_dir and jh_args shown in the following example. Here JupyterHub has been installed in a virtualenv that must be activate``d before use. In addition, SGE is told to ``j``oin the standard output and error output log files and to name the created batch job ``jupyterhub.
```
#!/bin/bash
#$ -j y
#$ -wd {{ working_dir }}
#$ -N jupyterhub

source /usr/virtualenvs/jupyterhub/bin/activate
python -m jupyterhub.singleuser {{ jh_args }}
```
