Yeah.  Our Xeon Phi 5110P should arrive on Tuesday, and then a friend of
mine who is to assemble this box will take a look and see what can be done.

We decided to go ahead and give this a try because there's no reliable
alternative.  3120A is not available yet (even though per
http://ark.intel.com/products/75797/Intel-Xeon-Phi-Coprocessor-3120A-6GB-1_100-GHz-57-core
it is "Launched"), and it might not be easy to buy even a few months
later.  I suspect that retail availability of 5110P here in Moscow could
be related to the recently built Russian supercomputer using these.
