JIP pipeline library

JIP Pipeline system

The JIP pipeline system is a python library and a set of command line utilities that allows you to create batch-process based computational pipeline that can be submitted and managed on a compute cluster or on your local machine.

Installation

The JIP documentation contains more detailed instructions on installation and, more importantly, configuration of the system and your compute infrastructure. Here is the very quick guide:

$> pip install pyjip

or

$> python setup.py install

If you want to install from pypi or the git repository. Afterwards, you have to create configuration file $HOME/.jip/jip.json and add the following content:

{
    "cluster": "<class_name>"
}

Replace <class_name> with the name of the class that implements support for your compute cluster. JIP ships with the following implementations:

• jip.cluster.SGE for Sun Grid Engine

• jip.cluster.Slurm for Slurm

• jip.cluster.PBS for PBS and Torque

• jip.cluster.LSF for Platform LSF and Open Lava

• jip.grids.JIP for JIPs’ internal scheduler. If you use this, make sure to start the JIP server on the same machine using the jip server command. Please note also that you have to install pyzmq if you want to run the JIP server.
