upgrade to fftw-3.3.10
The changes to fftw.spec
are:
- upgrading the package version to 3.3.10
- Adding a compiler switch that adds
--enable-avx512
for versions ofgcc
that support the instruction set (4.9.0)
I tested this in a SL7 container (gcc 4.8.5), and in a RL8 container (gcc 8). rpmbuild
builds and performs checks without issue. The RL8 libraries contain avx512 calls (according to nm
and grep
), but i haven't been able to test it because i don't have access to avx512 hardware.
