[Numpy-discussion] Re: Enhancement for AArch64 SVE instruction set

[kawakami . k]

Thanks for the reply.

To tell the truth, I am working on a trial implementation for SVE.
https://github.com/kawakami-k/numpy/commits/sve
At this time, some test patterns still fail, so I'm fixing them. When I finish 
this work, I would like to contribute it to NumPy.

As for my test environment, I use Fujitsu FX700 [0] that equips Fujitsu A64FX 
as its CPU. A64FX is based on Armv8.2-a and supports the SVE instruction set. I 
am not aware of any free SVE environment available in the cloud. 

If we can run Python and NumPy on qemu-aarch64 running on x64, can we do 
validation with qemu-aarch64? For example, oneDNN uses such method [1][2] to 
test its implementation for SVE.

[Numpy-discussion] New stable documentation

[Charles R Harris]

Hi All,

I've put up new stable documentation for NumPy 1.22.4. I'd appreciate it if
those familiar with how they want the documentation to look could take a
look at it so that fixes can be made while I'm still in the documentation
state.

Thanks Chuck. It all looks fine to me.

I'd say yes, we can do that. We are supporting other SIMD instructions that
we don't test in CI, so if it works on qemu during PR review then I think
that's enough.

Clearly there's a potential for issues here when we gain more SIMD support
that is not exercised in CI, so maybe we need a test strategy longer term
where we can run things under qemu at least in a weekly CI job or so (qemu
in regular CI isn't feasible, too slow).

Cheers,
Ralf
