Setting CPU limits
MapTiler Engine is a multi-threaded program. By default, it will use all the CPUs you have and print the information about the cores. You can also set a limit on the defined number of cores yourself with the -P option.
-P [num]Set number of CPU cores to be used for render process.
This is especially practical to evaluate the demo application before purchasing a license for a particular number of cores.
Modern CPUs have multiple cores and support Hyperthreading - which provides multiple logical CPUs per core. This way MapTiler Engine can provide higher performance with -P 4 even on a dual-core computer.
Demo trial extension
The demo version of MapTiler Engine is fully usable for 30 days after the first start. In case this trial period for testing the software before purchase expires and you would like to continue to test the demo, it is necessary to contact Klokan Technologies GmbH and request a trial extension key.
Such key can be then used with the parameter:
-extend_trial [TRIAL-KEY]Extends MapTiler Engine demo trial period.
And the demo can be then used during an extended time period.
