MultiThreading was introduced for rendering of different layer... in layer rendering is on single core. A GSOC project (https://qgisgsoc2015.wordpress.com/) introduced MT in Processing and was completed by Alexandre Bruy (if I well remember it would be available at least in processing master) Nyall Dowson is working in a QgsTaskManager and relative QgsTask class (https://www.youtube.com/watch?v=7pXBZtWYFJc) and probably Processing and Task Manager will converge in a while.
other than this you always create a plugin that run it's python process using all cores you want as stated by Nicolas Cadieaux... you should only have a lot of care using qgis classes, most of them are not thread safe in this moment. regards Luigi Pirelli ************************************************************************************************** * Boundless QGIS Support/Development: lpirelli AT boundlessgeo DOT com * LinkedIn: https://www.linkedin.com/in/luigipirelli * Stackexchange: http://gis.stackexchange.com/users/19667/luigi-pirelli * GitHub: https://github.com/luipir * Mastering QGIS: https://www.packtpub.com/application-development/mastering-qgis ************************************************************************************************** On 13 May 2016 at 21:29, Elstermann, Mike <[email protected]> wrote: > I have found the click for use more processor cores for rendering, > but how can QGIS use more processor cores for geoprocessing?
