EXCLUSIVE: Intel's Xeon Skylake ISA

___________________________  
99% BAD HARDWARE WEEK: CDI and AVX 512 F taken from forthcoming Knight Landing. Calculator ERI&PFI special instructions (sqrt and transc) remain inherently KNL's. Beside, it will use Storm Lake 100 Gbps integrated fiber optic fabric.  .
Storm Lake Gen 1 will support 2x100Gbps fiber optics, overall 50GB/sec fabric bandwith .
Aries interconnect routing chip, Intel has acquired from Cray in 2012, is able to support 16GBps. However, Intel's fiber optics failed for this year, so Storm Lake fabric support disappeared before Skylake Xeon announcement.
