https://software.intel.com/en-us/forums/intel-many-integrated-core/topic/737882 appears to cast doubt on the intent to support the coprocessor version of KNL.

I agree with Tim P: it appears uncertain whether the KNL coprocessor version is still available. You can still buy them online, however, for roughly USD 4000 a piece - that is actually more expensive than buying a new KNL server from scratch. Plus, with a KNL CPU you are no longer hindered by the PCIe bottleneck when accessing main memory; for computational problems requiring large amounts of RAM (well above 16 GB) this can be a real issue.

We managed to source them for more like $2100 apiece, which makes them slightly more reasonable. Still not worth the operational risk of finding out that we can't compile the necessary software for them and having to find buyers to sell them on, so we've chosen to go with the socketed processors instead.
