[Feature Request] Support value_or_pointer arguments for oneMKL functions #553

Open ndgrigorian opened 1 month ago

ndgrigorian commented 1 month ago

OneAPI spec delineates value_or_pointer which enables writing complex programs where the results of kernels can be chained together without bringing data to the host.

Providing these overloads would improve usability of oneMKL Interfaces.

I agree it would be nice to implement this feature already in the spec. The spec uses value_or_pointer only for the BLAS domain and USM API, would that be enough for your purposes? @oneapi-src/onemkl-blas-write do you have any plan to work on that?

Yes, it would be. It's also worth noting that rocBLAS and cuBLAS support pointers for scalar arguments.
