Sorry, I mistyped. (2) shouldn't be there.
(2) seems not supporting 64-bit index.
It's header uses "const int" as the type of index.
header available in bin:libatlas-base-dev
And I took a look into the netlib blas, aka the standard BLAS
implementation and it's index type is "const int" too ...
Not every BLAS provider can provide 64-bit-index API. It's fine if only
OpenBLAS (3), MKL (5), BLIS (4) can provide 64-bit-index API, because
they are basically the fastest cpu-based BLAS implementations publically
available.
