Hi, I have quickly given a look at some pointer. For example, some presentations at the EasyBuild meetup. There are slides with not so nice figures, e.g., p45 of [1] about FFTW. I remember similar number in other easybuild presentation.
In the Guix FFTW package definition, there is a comment about AVX. Well, is it still accurate ? Is Guix binary still slower than other ? [1] https://users.ugent.be/~kehoste/eum18/eum18_easybuild_past_present_future_20180130.pdf Thank you in advance for any pointer. All the best, simon
