|
Tool for profiling and testing the FFT libraries used in ABINIT.
|
|
Allowed options are:
|
|
fourdp --> Test FFT transforms of density and potentials on the full box.
|
|
fourwf --> Test FFT transforms of wavefunctions using the zero-pad algorithm.
|
|
gw_fft --> Test the FFT transforms used in the GW code.
|
|
all --> Test all FFT routines.
|
