[Clp] skylake xeons and AVX-512

[David Prime]

Hi all,

With the release of the new Xeon Skylake CPUs imminent and google compute
cloud offering early access to servers running them, I'm wondering if
there's any pre existing work or thoughts on how CLP performs with these
extra SIMD extensions?

I'm planning to get hold of a few servers as soon as I can and compile the
lib with various compilers/settings and see if there are any nice automatic
optimisations to be had. I'll share any benchmarks I generate and maybe we
can see if there's any further room for optimisation on these new
architectures.

Are there any clp specific build flags to enable/disable certain features
that could be relevant here?

Cheers,
David
