what happened to the -mmic option?

[durga_c_]

I am participating in the beta program for the 2018 compiler release. When I try to compile for the KNC with -mmic option, the compiler tells me that the option is not supported anymore. What is the replacement? Where can I learn more?

Yes, it has been removed. More details in the Release Notes.

KNC is no longer supported, and to target KNL please use -xMIC-AVX512 option.

So what is the roadmap for existing KNC users like me? Are we dead in the water, and the US dollars we invested in the hardware is worth the same number in Zimbaweian dollars?

I would also like an answer to this question.

Does it mean KNC users can never upgrade to compiler version 18 or above?

We will continue to support Intel® Xeon Phi™ X100 coprocessors in the Intel® Parallel Studio XE 2017 release and will continue to do so till Jan 2020.  The Intel® Xeon Phi™ X100 coprocessors have been announced End of Life (https://ark.intel.com/products/series/92649/Intel-Xeon-Phi-x100-Product-Family).

Forget about the -mmic option, can we still offload part of the code to xeon phi X100 using Intel 2018 C compiler ?
