Find the ideal dimension order for your TM1 cubes
Install required python packages:
pip install TM1py
pip install seaborn
Clone or download the optimus-py Repository from GitHub
- Adjust config.ini to match your TM1 environment
- Create uniquely named views in the relevant cubes
- Execute the
optimuspy.py - provide 7 arguments: -i (name of the instance) -c (name of the cube) -v (name of the cube view) -e (number of execution) -f (fast mode: True or False) -o (output: csv or xlsx) -u (update original order: True or False) -t (name of a ti process to measure runtime)
C:\Projects\optimus-py\optimuspy.py -i="tm1srv01" -c="Cube Name" -v="Optimus" -e="10" -f="True" -o="csv" -u=True -t="load.csv.file"
C:\Projects\optimus-py\optimuspy.py --instance="tm1srv01" --cube="Cube Name" --view="Optimus" --executions="15" --fast="True" --output="csv" --update=True --process="load.csv.file"
OptimusPy determines the ideal dimension order for every cube, based on RAM and query speed. For traceability and custom analysis, Optimus visualizes the results in a csv report and a scatter plot per cube.

- Run on the same machine
- Use big and representative views
- Choose a sensible number of
executions - Provide enough spare memory on TM1 server
- Fast mode determines first and last position only
- TM1py - A python wrapper for the TM1 REST API
- matplotlib - A comprehensive library for crating visualizations in Python.
