mpiicc architecture incompatibility on Xeon Phi x200 KNL

[Simone_Tinti]

Hello,

i receive the following errors while trying to compile High Performance Linpack for Intel Xeon Phi x200 (KNL), do you have any suggestion?

NOTES:

-same errors using different options like -x MIC-AVX512

-from documentation it's not clear to me if for x200 Xeon Phi the  lib and include files  shuold be the ones in /intel64 o /mic subfolders (that anyway seem to be selected automatically (mic version) at compile time  despite of  he LD_LIBRARY_PATH directories order)

Many thanks for your support

[TimP]

No, you must permit the linker to use the intel64 mkl libraries, not the ones which support only knc.

[Simone_Tinti]

Many thanks for you support, setting LD_LIBRARY_PATH properly solved this issue.

Simone.
