ILP64 BLAS Interface from Accelerate?

Up until now, we have been using an optimized BLAS library for Intel processors. Now we are looking for replacements for Apple Silicon. I know that Accelerate provides such an interface. However, I haven't been able to find if it provides an ILP64, rather than LP64, interface, which is what we use on all 64-bit platforms. If it does, how do I access it? Thanks.

Accelerate provides an LP64 interface for BLAS and LAPACK. You can find the headers under the Accelerate.framework umbrella header.

In macOS 13.3, Accelerate updated BLAS / LAPACK to align with v3.9.1 and also added ILP64 interfaces. Those new interfaces can be used by defining ACCELERATE_NEW_LAPACK preprocessor macro before including Accelerate / vecLib headers. For ILP64 interfaces, define ACCELERATE_NEW_LAPACK and ACCELERATE_LAPACK_ILP64 before including Accelerate / vecLib headers.

These details are noted in Accelerate's BLAS documentation and also in macOS 13.3 Release Notes
