[petsc-users] MPI-FFTW example crashes

[Sajid Ali]

 @Barry : Perahps config/BuildSystem/config/packages/fftw.py should use the
--host option when configure for PETSc is run with-batch=1.

If anyone here knows what --host must be set to for KNL, I'd appreciate it.

PS :  I know that Intel-MKL-FFT provides FFTW api. If I'd want to try with
this, is there a way to tell PETSc to pick fftw functions from MKL ?


Thank You,
