Quad precision is supported in AOCL-FFTW using the AOCC v2.2 compiler (AMD clang version 10 onwards).
Feature AMD application optimization layer has been introduced in AOCL-FFTW to uplift the performance of various HPC and scientific applications.
The configure option –enable-amd-app-opt enables this optimization layer and must be used with the master optimization configure switch –enable-amd-opt mandatorily.
This optimization layer is supported for complex and real (r2c and c2r) DFT problem types in double and single precisions.
Not supported for MPI FFTs, real r2r DFT problem types, Quad or Long double precisions, and split array format.
