Rather than look at hardware per se, how about learning about the Julia
language for this task?

I think your comments are wrong.
I think Intel was right on the mark with their "just throw a few flags and
it'll work". For a very large number of codes this will work. If you have
a simple FD, stencil or use MKL then your away. For a large number of
people that works.
Our company got up and
We aren't after average HPC programmers...
Even good compilers (Intel) are very very limited in their optimisations.
We got factors of 2x and 3x by hand writing SSSE3 commands on standard
Xeon's rather than let the compiler do its thing... Compiler limitations

I think the boundary between a final product and the start of a project
separates these two view points.
Lately, I short stacks of OReilleys scattered about, off libraries and a
second stack of notebooks filled with every command that really did work.
And I think it is fun.
