WebSep 30, 2012 · The compiler didn't complain about the serial routines; for example: the function "fftw_plan_dft_2d" seemed to compile successfully (after using the appropriate include-file in the code and linking to the MKL library), whereas "fftw_mpi_plan_dft_2d", which is the parallel (MPI) version of the same, did not. WebAOCL-FFTW achieves higher performance than the original FFTW 3.3.10 due to its various optimizations involving improved SIMD Kernel functions, improved copy functions (cpy2d and cpy2d_pair used in rank-0 transform and buffering plan), improved 256-bit kernels selection by Planner and an optional in-place transpose for large problem sizes. dj torino
