SCALFFT_MID_A2A_ALGO
Set the transpose algorithm for the mid-stage of 3D FFT computations.
Parameters
See SCALFFT_PRE_A2A_ALGO.
Examples
- All transpositions during the 3D FFT mid-stage can be forced to use the linear algorithm by setting the environment variable -x SCALFFT_MID_A2A_ALGO=2.
- The two transpositions of the 3D FFT mid-stage can be configured to use the linear and pipelined algorithms, respectively, by setting the environment variable -x SCALFFT_MID_A2A_ALGO=2,4.
- The three transpositions of the 3D FFT mid-stage can be configured to use the linear, pairwise, and pipelined algorithms, respectively, by setting the environment variable -x SCALFFT_MID_A2A_ALGO=2,3,4.
