If I use "Selective Gaussian Blur" in Gimp, only one CPU gets used. My PC has four.

Is there a way to tell Gimp to use all available CPUs?

Some operations take quite long, and this would reduce the time I need to wait.


Multi-threading for GIMP filters will be introduced with GEGL support in future releases. At present there is work in progress to port Gaussian blur but this is not yet available.

As an alternative we can use the third-party plugin G'MIC which claims to at least partially support multi-threading. This plugin is available through the gimp-plugin-registry Install gimp-plugin-registry or newer version from ppa:otto-kesselgulasch/gimp.

  • Thank you for this answer. I will use the third party plugin. About "Wait for GEGL". I am not sure what will come first: GNU Hurd, Perl 7 or Gimp with full GEGL support. I hope you don't feel offended by this joke :-) – guettli Jan 15 '15 at 9:17
