So does yours and everyone else, I am guessing that Joe forgot to change that number.

'Tis true. Luckily having only one set of transposes serves well to distinguish J37 from J34.
The test outputs are appreciated, I'd hate to break something and not know it because of the limited systems I have.

Thanks very much, it seems I've reached the initial goal of having working avx variants for all the tested categories. I'll do some tweaking to see if I can improve performance.

On GPU pulse finding looks memory-bound...
Maybe GaussFit ? It's compute intensive search.

Here's another test, added a third variant AVX chirp which might be marginally faster and a second variant AVX folding set, ditto. AFAIK no changes to the non-AVX code other than making sure this one identifies itself correctly :D
