If one tries to run the LISA inference example using an MKL backend the code fails with Intel MKL DFTI ERROR: Invalid configuration parameters. I believe this is the same error as IntelPython/mkl_fft#57, and seemed to be caused there by array sizes > 2^24. (Indeed the LISA example first successfully does an FFT of length 12614400 before failing at length 19457280).
LIGO arrays are generally not as long as this, but it will be common to have lengths like this in LISA, so avoiding MKL in that context might be needed (especially if we move to MKL as default FFT backend).
