Note I added an ifdef for NET8_0_OR_GREATER because my assumption is all of this is going to be backported to the release/8.0 branch, at which point we'll also be building for net7.0.

Just does two functions to establish the files into which the rest of the implementations can be moved.

Issue Details

Just does two functions to establish the files into which the rest of the implementations can be moved, so we can work on this in parallel on the rest.

If you had something else in mind, just let me know.

(I'm revamping as well, to share more code between the various operations. Will post an update shortly...)

I pushed a new commit that:

  • Handles most of the other operations that were there. It currently leaves out the log/exp/trig functions.
  • Shares the implementations using an interface and either static abstract interface methods (in .NET Core) or an instance-based interface with a dummy parameter passed (in .NET Standard)
  • Updates the logic to handle the trailing elements with a single final vector rather than cascading through smaller-width vectors

I did not add any logic for alignment. I'll leave that for you, Tanner, for a subsequent change if you think it's valuable enough.

* Start vectorizing TensorPrimitives (#91596)

* Start vectorizing TensorPrimitives

Just does two functions to establish the files into which the rest of the implementations can be moved.

* 6 more naive methods for Tensor Primitives. (#92142)

* 6 more naive methods

* updates from pr comments

* Add remaining set of TensorPrimitives APIs for .NET 8 (#92154)

* Add remaining set of TensorPrimitives APIs for .NET 8

Adds non-vectorized implementations of:
- Max
- Min
- MaxMagnitude
- MinMagnitude
- IndexOfMax
- IndexOfMin
- IndexOfMaxMagnitude
- ConvertToHalf (only on .NET Core)
- ConvertToSingle (only on .NET Core)
- IndexOfMinMagnitude

Adds vectorized implementations of:
- Sum
- SumOfSquares
- SumOfMagnitudes
- Product
- ProductOfSums
- ProductOfDifferences

Also includes the helpers that'll make it trivial to vectorize Dot.

Beyond vectorizing the non-vectorized ones, the vectorized implementations should be improved further, including:
- Handling alignment better
- Vectorizing the remainder that doesn't fit in a vector rather than falling back to scalar

* Cleanup after previous PR, vectorize CosineSimilarity/Dot/L2Normalize/Distance, add tests

* Address PR feedback, and fix a few other issues

* Fix TensorPrimitives.CosineSimilarity to use vectorized implementations (#92204)

* Fixed duplicated code from merge.

* New Microsoft.BCL.Numerics package (#91074)

* bcl numberics library added

* bcl done

* added explicit 2.1 target

* Minor doc updates

* Apply suggestions from code review

Co-authored-by: Viktor Hofer <viktor.hofer@microsoft.com>

* fixes from PR comments

* minor csproj fixes

* fixed ref target frameworks

* minor ref csproj updates

* minor csproj updates
