Altair Units License
Read more: Altair Units License for RapidMiner AI Hub
When RapidMiner Studio is configured to use the Altair Units License, it draws Altair Units based on the Parallel execution value defined in Preferences.
The baseline for using RapidMiner Studio is 20 Altair Units. If fewer than 20 units are available, RapidMiner Studio will provide an error message.
The baseline number of 20 Altair Units allows RapidMiner Studio to use 8 threads. If the number of threads is increased, the number of Altair Units also increases, at a rate of 5 Altair Units per thread. For example, RapidMiner Studio configured with 12 threads draws 40 Altair Units.
