this is great, thanks!
but wait... we /beat/ intel MKL???

this is awesome but... we need to triple-check this before we publish.
MKL and GOTO are normally very close to each other, and close to the
theoretical maximum. In your results, MKL does surprisingly poorly.
Is there something wrong in your MKL setup?
