Description Jan 2017-02-21 16:02:23 UTC 
The Face detection is using all CPU cores whether I checked the option "work on all processor cores (experimental)" or not.

I tried both the system package from openSUSE Tumbleweed and the AppImage.
Comment 1 Jan 2017-02-27 07:30:52 UTC 
It seems that digiKam uses all CPU cores only by using the options "Scan again and merge results" and "Detect faces" (or "Detect and recognize faces").

By using "Skip images already scanned" it uses only one core.
Comment 2 caulier.gilles 2019-03-20 15:16:09 UTC 
After 3 weeks of work, i finally completed the compilation of AppImage using Qt
5.11.3 + QWebkit 5.212.

New 6.1.0 pre-release AppImage bundle can be found here (64 bits only for the
moment) :

https://files.kde.org/digikam/

Please check if this bugzilla entry still valid.

Thanks in advance

Not reproduce with digiKam 7.0.0-beta1 using new Face management based on OpenCV Neural Network to perform face detection and Recognition with Deep Learning algorithm.

I close this file now.
