./math/fftwf, Collection of fast C routines to compute DFTs

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 3.3.6pl1, Package name: fftwf-3.3.6pl1, Maintainer: pkgsrc-users

FFTW is a free collection of fast C routines for computing the
Discrete Fourier Transform in one or more dimensions. It includes
complex, real, symmetric, and parallel transforms, and can handle
arbitrary array sizes efficiently. FFTW is typically faster than
other publically-available FFT implementations, and is even
competitive with vendor-tuned libraries. (See our web page for
extensive benchmarks.) To achieve this performance, FFTW uses novel
code-generation and runtime self-optimization techniques (along with
many other tricks).

This package provides the single precision library.

Log message:
Updated fftwf to 3.3.6pl1.

FFTW 3.3.6-pl1:

* Bugfix: FFTW 3.3.6 had the wrong libtool version number, and generated
  shared libraries of the form libfftw3.so.2.6.6 instead of
  libfftw3.so.3.*.

FFTW 3.3.6:

* The fftw_make_planner_thread_safe() API introduced in 3.3.5 didn't
  work, and this 3.3.6 fixes it.  Sorry about that.
* compilation fixes for IBM XLC
* compilation fixes for threads on Windows
* fix SIMD autodetection on amd64 when (_MSC_VER > 1500)

Log message:
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.

Log message:
Bump PKGREVISION for perl-5.24.0 for everything mentioning perl.
   2016-04-03 14:45:39 by Joerg Sonnenberger | Files touched by this commit (2)
Log message:
Similar to math/fftw, include the thread version when native threading
exists. Bump revision.

Log message:
Update fftwf to 3.3.4, to match fftw.

FFTW 3.3.4

* New functions fftw_alignment_of (to check whether two arrays are
  equally aligned for the purposes of applying a plan) and fftw_sprint_plan
  (to output a description of plan to a string).

* Bugfix in fftw-wisdom-to-conf; thanks to Florian Oppermann for the
  bug report.

* Fixed manual to work with texinfo-5.

* Increased timing interval on x86_64 to reduce timing errors.

* Default to Win32 threads, not pthreads, if both are present.

* Various build-script fixes.

FFTW 3.3.3

* Fix deadlock bug in MPI transforms (thanks to Michael Pippig for the
  bug report and patch, and to Graham Dennis for the bug report).

* Use 128-bit ARM NEON instructions instead of 64-bits.  This change
  appears to speed up even ARM processors with a 64-bit NEON pipe.

* Speed improvements for single-precision AVX.

* Speed up planner on machines without "official" cycle counters, such \ 
as ARM.
