Higher ColourSpace licenses (INF/XPT/PRO LMN/LGN & HTX/HTP) are Multi-Threaded, enabling all available CPU threads to be utilised during processor hungry operations, such as LUT Generation.
Multithreading means multiple operation can be performed simultaneously, and LUT Generation is far faster than for lower ColourSpace license levels.
Multithreading
The number of CPU threads dedicated to each LUT Generation process can be set by an Environment Variable, as defined within the Customer Downloads documentation. If not set, all available CPU threads are used.
With ColourSpace's Multithreading capability multiple LUTs can be generated simultaneously, either by using the Create button multiple times with different Source/Destination configurations, or via opening multiple LUT Generation windows, again with different Source/Destination configurations.
Additionally, other ColourSpace functions can be accessed while LUTs are being generated, enabling saved profiles to be reviewed, etc.
Note that due to the nature of the required processing, the Gamut Mapping component of LUT Generation is not Multi-Core capable.
