Cluster FFT Interface
- C/C++:#include "mpi.h"
- Descriptor Manipulation. There are three functions in this category. TheDftiCreateDescriptorDMfunction creates an FFT descriptor whose storage is allocated dynamically. TheDftiCommitDescriptorDMfunction "commits" the descriptor to all its settings. TheDftiFreeDescriptorDMfunction frees up the memory allocated for the descriptor.
- Descriptor Configuration. There are two functions in this category. TheDftiSetValueDMfunction sets one specific configuration value to one of the many configuration parameters. TheDftiGetValueDMfunction gets the current value of any of these configuration parameters, all of which are readable. These parameters, though many, are handled one at a time.
