Mark, were you trying this in Valgrind with a binary targeting KNL, i.e.,
built to use AVX-512 instructions? I don't think Valgrind implements all
(or any?) of those, so a failure is not a surprise. Indeed, I've had
Valgrind choke on some AVX2 instructions, though maybe the most recent
versions of Valgrind will handle these properly now.
