Distributed job execution application built for Galaxy (

Project description

This project is a Python server application that allows a Galaxy server to run jobs on remote systems (including Windows) without requiring a shared mounted file systems. Unlike traditional Galaxy job runners - input files, scripts, and config files may be transferred to the remote system, the job is executed, and the results are transfered back to the Galaxy server - eliminating the need for a shared file system.

Full documentation for the project can be found on Read The Docs.

Configuring Galaxy

Galaxy job runners are configured in Galaxy’s job_conf.xml file. Some small examples of how to configure this can be found here, but be sure to checkout job_conf.xml.sample_advanced in your Galaxy code base or on Github for complete information.


Full details on different ways to install Pulsar can be found in the install section of the documentaiton, but if your machine has the proper Python dependencies available it can be quickly download and a test job run with.

mkdir pulsar
cd pulsar
virtualenv venv
. venv/bin/activate # .venv\Scripts\activate if Windows
pip install pulsar-app
pulsar --daemon # just pulsar if Windows
pulsar-check # runs a test job

The configuration documentation has many details on securing your Pulsar server and enabling advanced features such as cluster integration and message queue communication.

Development and Testing

The recommended approach to setting up a development environment for Pulsar on Linux or Mac OS X is rougly as follows:

git clone
cd pulsar
virtualenv .venv
. .venv/bin/activate # .venv\Scripts\activate if Windows
pip install -r requirements.txt
pip install -r dev-requirements.txt

This project is distributed with unit and integration tests (many of which will not run under Windows), the following command will install the needed python components to run these tests. The following command will then run these tests:

make tests

The following command will then produce a coverage report corresponding to this test and place it in the coverage_html_report subdirectory of this project.:
