Update fftw{,f} to 3.3.5.
FFTW 3.3.5:
* New SIMD support:
- Power8 VSX instructions in single and double precision.
To use, add --enable-vsx to configure.
- Support for AVX2 (256-bit FMA instructions).
To use, add --enable-avx2 to configure.
- Experimental support for AVX512 and KCVI. (--enable-avx512, --enable-kcvi)
This code is expected to work but the FFTW maintainers do not have
hardware to test it.
- Support for AVX128/FMA (for some AMD machines) (--enable-avx128-fma)
- Double precision Neon SIMD for aarch64.
This code is expected to work but the FFTW maintainers do not have
hardware to test it.
- generic SIMD support using gcc vector intrinsics
* Add fftw_make_planner_thread_safe() API
* fix #18 (disable float128 for CUDACC)
* fix #19: missing Fortran interface for fftwq_alloc_real
* fix #21 (don't use float128 on Portland compilers, which pretend to be gcc)
* fix: Avoid segfaults due to double free in MPI transpose
* Special note for distribution maintainers: Although FFTW supports a
zillion SIMD instruction sets, enabling them all at the same time is
a bad idea, because it increases the planning time for minimal gain.
We recommend that general-purpose x86 distributions only enable SSE2
and perhaps AVX. Users who care about the last ounce of performance
should recompile FFTW themselves.
