That option disables a lot of optimizations, so it would not astonish me 
if that were among them.

Of course, Intel provides highly optimized and carefully coded BLAS 
routines in its MKL, similar to most HPC vendors. It's not clear to me 
why one would care about "reference" routines. (I did not read the article.)
