oneDAL supported algorithms

oneAPI Data Analytics Library (oneDAL) is a library providing highly optimized machine learning and data analytics kernels. Some of these kernels is integrated into ML.NET via C++/C# interoperability.

oneDAL Documentation | oneDAL Repository

Please note that oneDAL acceleration paths are only available in x64 architectures

Integration consists of:

• A "native" component (under src/Native/Microsoft.ML.OneDal) implementing wrapper to pass data and parameters to oneDAL;
• Dispatching to oneDAL kernels inside relevant learners: OLS (src/Microsoft.ML.Mkl.Components), Logistic Regression (src/Microsoft.ML.StandardTrainers), Random Forest (src/Microsoft.ML.FastTree);

Running ML.NET trainers with dispatching to oneDAL kernels

Currently, dispatching to oneDAL inside ML.NET is regulated by MLNET_BACKEND environment variable. If it's set to ONEDAL, oneDAL kernel will be used, otherwise - default ML.NET.
