AMD Optimized FFTW version 3.1

Highlights of improvements on AMD EPYC^TM processor family CPUs

• Feature ‘AMD application optimization layer’ that uplifts the performance of HPC and scientific applications
• Feature ‘Fast MPI transpose algorithm’ to speed up the distributed MPI FFT computations
• Feature ‘Top N planner’ that minimizes single-threaded run-to-run variations
• Support for building AMD FFTW library on Windows
• GCC compilation support for AMD processors based on the AMD “Zen3” core architecture

AMD Optimized FFTW version 3.0.1

AMD Optimized FFTW version 3.0.1

Highlights of improvements on AMD EPYC^TM processor family CPUs

• A new planner feature called Top N planner is introduced that minimizes single-threaded run-to-run variations.
• New parallel MPI transpose algorithm enabled via configure option "--enable-amd-mpi-vader-limit"
  • When using this configure option, the user needs to set --mca btl_vader_eager_limit appropriately (current preference is 65536) in the MPIRUN command.

AMD Optimized FFTW version 3.0

AMD Optimized FFTW version 3.0

Highlights of improvements on AMD EPYC^TM processor family CPUs

• New fast planner that improves the time of various planning modes in general and OPATIENT mode in particular. It can be enabled through configure option “–enable-amd-fast-planner”
• Support for configure option “AMD_ARCH” to help cross compilation. It can take various options like auto/znver1/znver2/znver3 for AMD EPYC processors
• Quad precision support is now included for AOCC clang compiler from version 10 onwards
• Improved handling of –enable-debug and “CC” options by ‘configure’ when –enable-amd-opt is used
• Fixed the wrong behavior of OWISDOM feature in the absence of wisdom file
