Erlang should run more than fine on those, although you may need to mess
around with the NUMA topology (see the +sct flag to erl;
http://erlang.org/doc/man/erl.html).  Do share what you find if you take
the plunge!

A word of warning: many of the older Xeon Phi systems were designed for
datacenters, so were rackmount, took non-standard power and had
hell-banshee cooling fans that made sitting in the same room impossible.
Make sure to read the label and match it to your situation before placing
the request.
