Parallel Three-Dimensional Fast Fourier Transforms 2.3.1 (Default branch)
Parallel Three-Dimensional Fast Fourier Transforms, dubbed P3DFFT, is a library for computing 3D FFTs using 2D (pencil) decomposition. It is written using Fortran with MPI, and is tuned to work on multiple single-CPU systems (up to 32768 of them). It is built to leverage high-performance serial 1D FFT libraries, such as FFTW or ESSL.License: Public DomainChanges:
An option has been added to overwrite the(complex) input array when using thecomplex-to-real transform with FFTW. An option hasbeen added to use data layout using unit-stride onoutput of the real-to-complex routine, i.e.(Z,X,Y) ordering.Image

Class::Accessor::Fast(3pm)				User Contributed Perl Documentation				Class::Accessor::Fast(3pm)

NAME

       Class::Accessor::Fast - Faster, but less expandable, accessors

SYNOPSIS

	 package Foo;
	 use base qw(Class::Accessor::Fast);

	 # The rest is the same as Class::Accessor but without set() and get().

DESCRIPTION

       This is a faster but less expandable version of Class::Accessor.  Class::Accessor's generated accessors require two method calls to
       accompish their task (one for the accessor, another for get() or set()).  Class::Accessor::Fast eliminates calling set()/get() and does the
       access itself, resulting in a somewhat faster accessor.

       The downside is that you can't easily alter the behavior of your accessors, nor can your subclasses.  Of course, should you need this
       later, you can always swap out Class::Accessor::Fast for Class::Accessor.

       Read the documentation for Class::Accessor for more info.

EFFICIENCY

       "EFFICIENCY" in Class::Accessor for an efficiency comparison.
