Hi guys,
I am trying to understand how the x86 dispatch for ndarray sort works. The
following call in Line 137 of numpy/core/src/npysort/quicksort.cpp returns 0
for my test cases:
if (x86_dispatch<Tag>::quicksort(start, num))
return 0;
I have tried to compile with --cpu-dispatch="AVX512_KNL AVX512_CLX AVX512_CNL
AVX512_ICL AVX512_SKX" but for dtype=uint64 (or int64 or uint8 or float32 or
float64) it always the same result, i.e., the standard quicksort is used
instead of the AVX512 one with bitonic sorting base cases.
What do I have to do to be able to use the AVX512 implementation?
I am currently compiling on a MacBook Pro with Monterey. I have all kinds of
Linux machines available, if that should be a requirements.
Thanks in advance for any insights!
Cheers,
Peter
