Is there a planned release for MathNet.Numerics.MKL.Linux nuget Package?

[sudiptob2]

Hey, MathNet community, we’re encountering issues using MathNet.Numerics with Intel MKL on Linux. We'd appreciate your input and guidance on how best to proceed.

Problem Statement

To work with intel-mkl on Linux, MathNet.Numerics requires the MathNet.Numerics.MKL.Linux provider. The latest version of this provider (3.0.0-beta3) is distributed as a separate NuGet package, but it is outdated since its last release in 2022 and incompatible with the latest intel-mkl library.

While it’s possible to build the provider from the master branch using the mkl_build.sh script, this approach is less convenient than installing via NuGet. Additionally, the script often requires manual tuning based on the user’s environment to work correctly.

To Reproduce

Install intel-mkl: apt-get install intel-mkl

Create a test project:

using MathNet.Numerics;
using MathNet.Numerics.LinearAlgebra;
class Program
{
    static void Main()
    {
        Control.UseNativeMKL();
        MathNet.Numerics.Providers.MKL.MklControl.UseNativeMKL(MathNet.Numerics.Providers.MKL.MklConsistency.AVX2);
        MathNet.Numerics.Providers.LinearAlgebra.LinearAlgebraControl.Provider.InitializeVerify();
        Console.WriteLine("Provider: " + MathNet.Numerics.Providers.LinearAlgebra.LinearAlgebraControl.Provider);
        var matrix = Matrix<double>.Build.Random(3, 3);
        Console.WriteLine(matrix);
    }
}

.csproj file

...
  <ItemGroup>
    <PackageReference Include="MathNet.Numerics.MKL.Linux" Version="3.0.0-beta3" />
  </ItemGroup>
...

Output:

Unhandled exception. System.NotSupportedException: MKL Native Provider too old. Consider upgrading to a newer version.

Potential Solution

Release a new version of the Linux MKL provider based on the latest improvements in the master.

We’re wondering if there are any plans to release an updated version of the Linux MKL provider via NuGet, or if there’s anything we can contribute to help move this forward.
