3.1 Data Alignment

d@0: d@0:

In order to get the best performance from FFTW, one needs to be d@0: somewhat aware of two problems related to data alignment on x86 d@0: (Pentia) architectures: alignment of allocated arrays (for use with d@0: SIMD acceleration), and alignment of the stack. d@0: d@0: d@0: d@0:
