Towards 2.3

[DiamonDinoia]

I am creating this milestone to discuss what goes in 2.3 and what is left to do. This can be extended once the switching to template tasks are formalized.
The main changes are:

• Spreader performance improvements with manual vectorization Spreader manual vectorization #459
• Interp perfomance improvements with manual vectorization and compile flags Interp vectorization #471
• Kernel vectorization Spreader manual vectorization #459
• Migrating to modern pyproject.toml from deprecated setup.py [DRAFT] Using pyproject.toml and Cmake to build wheels #429
• Kernel use Estrin and exploit coefficient symmetry to reduce the number of operations Potential savings for polynomial approximation #461 Horner's rule for polynomial evaluation with symmetry idea diccussed in discussions #461 #477
• Optimizing foldrescale, removes the input range limitations Optimising foldrescale #440
• Switchable FFT, support for DUCC FFT Add optional DUCC FFT support #463
• DUCC FFT documentation add makefile (and document) DUCC FFT option #479

Hi Marco, I'm not sure where you got "3.0" from. That is a big management decision. We had discussed calling the next release 2.3, since no interface/API are going to change (please). Thanks for gathering the list of things currently on the plate - the list seems to include things already in master (#459, #471, #440, etc) We have to make some decisions about what other nearly-ready things go into 2.3. I propose *not* to include the larger changes that are only just begun, or not even begun at all (de-macroizing, templating, type 3 on GPU, dispatch). Could we make 2.3 the goal for now, and finish up for it *only*: #429 #461 #477 #479 Everything else should wait! (even #488 needs work on 3D,etc that means it should be decoupled from the rest). Decoupling is crucial to maintain sanity here. Thanks! Alex

I also have to add for 2.3 the kernel coeff regeneration I'm currently doing for upsampfac=2.0. I think upsampfac=1.25 kernel xsimd eval should be left for 2.3.1.
There are lots of interacting issues here and we have to be a bit less ambitious and take it step by step.

[DiamonDinoia]

Sounds good. The main point of this issue/milestone is to discuss and prioritize the various tasks.

I applaud the organization effort - just to scale back the number of things a lot here.

Ok. If you can redo your milestone tagging with 2.3 according to my above scheme, that would make everything feel a little more in control - thanks !:)
