Research direction

Start by tracing ndarray's BLAS integration and the fallback used for arrays whose dimensions exceed regular OpenBLAS's 32-bit limit. Determine the changes needed to use 64-bit index, stride, and dimension sizes, with completion defined by removing that fallback while preserving array operations.

Written by the indexing model from the issue text.

Description

blas

Using 64-bit BLAS allows removing the fallback for arrays with dimensions larger than the 32-bit supported by regular openblas.

64-bit refers to the index / stride / dimension size used.
