For MS Windows gretl supplies the standard lapack and netlib
"reference blas", cross-compiled using gcc on Linux. I think it's
lapack/blas version 3.1.1 but I'll have to check. Anyway, no sse,
since that's not supported by the vanilla netlib code.
So there is no (easily available) SSE-optimized lapack/blas version for
Windows? I'm asking because recent gretl versions have the sse
requirement anyway, so this wouldn't introduce a new hardware
restriction it seems.
Well this is nothing I really need myself actually, as I said, out of
curiosity.
thanks,
