The site is built with Django therefore the official Django documentation applies to maintaining and deploying the site:
A recipe submitted for execution is called a job.
When the job is run the recipe parameters are applied onto recipe template to produce the script that gets executed. This transformation takes place right before executing the job.
Jobs can be executed as commands. See the job command for details:
python manage.py job --help
The command has number of parameters that facilitate job management and recipe development. For example:
python manage.py job --list
will list all the jobs in the system. Other flags that allow users to investigate and override the behaviors.
python manage.py job --id 4 --show_script
will print the script for job 4 that is to be executed to the command line. Other flags such as -use_template and -use_json allows users to override the data or template loaded into the job.
This can be useful when developing new recipes.
Another handy command:
python manage.py job --next
will execute the next queued job. The job runner may be run periodically with cron.
The Biostar Engine supports uwsgi. When deployed through
uwsgi jobs are queued and run automatically through the uwsgi spooler. See the uwsgi documentation for details on how to control and customize that process.

Note: The site is designed to execute scripts on a remote server. In addition the site allows users with moderator rights may change the content of these scripts.
It is extremely important to monitor, restrict and guard access to all accounts with moderator privileges!
