Parallel Three-Dimensional Fast Fourier Transforms 2.3 (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:
A C interface has been added. More examples havebeen added: in-place transform and power spectrumcalculation. Performance improvements have beenmade. Ghost cell support was added fornearest-neighbor communication. Several bugs havebeen fixed.Image

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. AUTHORS
