Imagemagick only uses one core
Posted: 2013-07-15T11:19:33-07:00
I am running an Ubuntu server with 8 cores. However imagemagick always only uses 1 single core.
Running `identify -version` returns:
So OpenMP which is apparently needed for multi threading is enabled.
Running a benchmark with -bench option (e.g. convert logo: -resize 500% -bench 10 logo.png) as described here: http://stackoverflow.com/questions/1172 ... erformance returns
It does however not return Performance[1] through Performance[8] as described in the manual: http://docs.snake.de/ImageMagick/www/parallel.html which makes me wonder.
Any ideas how I can get imagemagick to use all 8 cores?
