Setting CPU limits¶
MapTiler 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.
maptiler -P 4 ...
This is especially practical to evaluate the demo application before purchasing a license for a particular number of cores.
The modern CPUs has multiple cores and support of Hyperthreading - which provides multiple logical CPUs per core. This way MapTiler can provide higher performance with -P 4 even on a dual-core computer.
Demo trial extension¶
The demo version of MapTiler 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 and request a trial extension key.
Such key can be then used with the parameter:
And the demo can be then used during an extended time period.
Software activation online¶
After a purchase of the software, when you receive your license key, it is necessary to activate MapTiler. After activation, the demo version no longer enforces the “MapTiler DEMO” overlays.
To do the online activation, use the following command:
￼maptiler -activate YOUR-OWN-LICENSE-KEY
In case you require to reinstall the computer, use -deactivate command to be able to re-activate the license later on.
Software activation in a virtual machine¶
The activation process for MapTiler running in a virtual machine requires online activation only via environment variable MAPTILER_LICENSE. The software will be automatically deactivated in the end.
Example on Windows OS
set MAPTILER_LICENSE=YOUR-OWN-LICENSE-KEY maptiler ...
Example on Linux / macOS
export MAPTILER_LICENSE=YOUR-OWN-LICENSE-KEY maptiler ...
Notice: This activation process via environment variable requires not-activated MapTiler Pro instance on that computer! Starting MapTiler application without setting this environment variable MAPTILER_LICENSE, you should see either MapTiler Pro Demo, or Your trial period has expired error message.
You can deactivate MapTiler Pro via command line, in order to transfer the application to another computer. Note that after the deactivation, MapTiler Pro will continue to run in DEMO mode, but the trial period of 30 days will NOT start again.
To do the online deactivation, use the following command:
To check your license information, use the following command:
maptiler -license Email: <your email> License: <your license key> Purchased CPU cores: 4 Maximum usable cores: 4 maptiler -license Remaining 0 days on the trial. Maximum usable cores: 4
Software activation offline¶
For computers which are not directly connected to the Internet or which are in security restricted installations, we have support for offline activation as well.
To use the offline activation with the key we supply you after purchase you need to call:
￼maptiler -activate_request YOUR-OWN-LICENSE-KEY request.xml
This will generate a “request.xml” file, which you must send to us by email, and we will provide you with a “response.xml” file back. This can be used to activate the MapTiler by running:
￼maptiler -activate_response response.xml
If at any time you will want to deactivate MapTiler, eg. to move it to another machine, run the following command and you have to send us again the newly generated “request.xml” file.
￼maptiler -deactivate_request request.xml
The offline activation is not available in a virtual machines. For more information see Software activation in a virtual machine above.
