OpenRenderManagement is an open-source render management project.

The Core project is entirely written in python.

Currently, Puli is only supported on Linux (32 or 64 bits).

The manager is the main server component, it holds the following subsystems:

• a central db
• a dispatcher daemon

• mysql-devel
• python-devel (for your version of python)

• python-tornado
• MySQL-python
• python-sqlobject
• requests

A render node is installed on each machine that can holds a rendering process. It holds the following subsystems:

• a worker daemon
• an optionnal commandwatcher process when a process is currently rendering

• python-tornado
• requests
• psutil

Several tools can be installed on a separate computer to operate the system:

• puliquery: command line request tools
• puliexec: simplify submission of scripts and command line
• pulistats: set of script to trace graphs based on server statistics
• pulistatsviewer: GUI program to trace and display graphs

• python-tornado
• numpy
• pygal
• pyqt4

Execute the following mysql commands to create the database and the dedicated user:

create database pulidb character set utf8;
create user puliuser identified by 'yourpasswd';
grant all privileges on pulidb.* 
      to 'puliuser'@'localhost' 
      identified by 'yourpasswd' with grant option;

You can copy the octopus folder containing all the code to wherever you like (for example /opt/puli) just make sure this dir is in your PYTHONPATH.

Create the folders conf and logs in the install dir.

The settings are located in the file /opt/puli/octopus/dispatcher/settings.py.

Please check the following settings:

CONFDIR = /opt/puli/conf
LOGDIR = /opt/puli/logs
POOLS_BACKEND_TYPE = "file"
DB_ENABLE = True
DB_CLEAN_DATA = True

To launch the dispatcher, execute the following command in a shell:

python /opt/puli/scripts/dispatcherd.py -D -C

Upon the first execution, Puli will create the appropriate tables in the database.

For the following executions, you may set these parameters in the settings file:

POOLS_BACKEND_TYPE = "db"
DB_ENABLE = True
DB_CLEAN_DATA = False

These will tell Puli to init itself with the database that was previously created, and it will enable the persistence of the jobs.

If you want to erase the database in order to have a clean start, reset these parameters to the values in the installation section.

The model needs a bit of a refactoring. It has been designed several years ago to address some use-cases that are no longer relevant. It can be more simple and straightforward than it is now.

Several aspects of the worker can be optimized (like the handling of status and completion update, and the interaction between the cmdwatcher and the process)
