Creating MPI FFTW2 Wrapper Library
The source code for the wrappers, makefiles, and
files with lists of wrappers are located in the
directory.
.\interfaces\fftw2x_cdft
subdirectory in the Intel® oneAPI Math Kernel Library
A wrapper library contains C wrappers for Complex
One-dimensional MPI FFTW Transforms and Complex Multi-dimensional MPI FFTW
Transforms. The library also contains empty C wrappers for Real
Multi-dimensional MPI FFTW Transforms. For details, see
MPI FFTW Wrappers Reference.
Parameters of a makefile specify the platform
(required), compiler, and data precision. Specifying the platform is required.
The makefile comment heading provides the exact description of these
parameters.
To build the library, run the
make
command on Linux* OS and
macOS* or the
nmake
command on Windows* OS
with appropriate parameters.
For example, on Linux OS the command
make
libintel64
builds a double-precision wrapper library for Intel®
64 architecture based applications using Intel MPI and the Intel®
C++ Compiler (compilers and data precision are
chosen by default.).
A makefile creates the wrapper library in the directory with the libraries corresponding to the used platform. For example,
Intel® oneAPI Math Kernel Library
./lib/ia32
(on
Linux OS) or
.\lib\ia32
(on
Windows* OS).
In the wrapper library names, the suffix corresponds
to the used data precision. For example,
fftw2x_cdft_SINGLE.lib
on Windows OS;
libfftw2x_cdft_DOUBLE.a
on Linux OS.
