The heavy lifiting in LAPACK is delegated to BLAS. So if you build
LAPACK against ATLAS or GotoBLAS, LAPACK does not tend to be the
Both ATLAS and GotoBLAS reimplements some routines from LAPACK. But they
will not give you a full LAPACK.
To avoid LAPACK overshadowing LAPACK routines in GotoBLAS, see this:
MKL has both LAPACK and BLAS, but it is very expensive. I don't know if
Intel has reimplemented LAPACK, but that would surprise me, as it would
suffice to make a fast BLAS.
