Andysen0,

What doesn’t work about it? I’m not too familiar with Cmake so this might be an issue specific with your Cmake config, but specify the acclerator target with the -ta option. Use -ta=tesla for GPU acceleration and -ta=multicore for multicore. You should see the -Minfo messages give you feedback for the target.
