Compiling For The Intel® Xeon Phi™ Architecture (codename Knights Landing)
---------------------------------------------------------------------------
``ispc`` starting from v1.9.0 has support for compiling for the second
generation of Intel® Xeon Phi™ architecture (codename Knights Landing).
Two compilation paths are supported - generic (similar to KNC support) and
native.
To compile using generic path, follow KNC instructions, but use knl.h, instead
of knc.h and use -xMIC-AVX512 for ICPC instead of -mmic.
To compile using native path, just set --target=avx512knl-i32x16.
Going forward, generic path will be deprecated, so using native target is
preferable way to get AVX512 support.
