The Intel compiler probably was not able to detect the processor(s) that your system uses, such that it generated an executable using instruction sets that are wrong for your system. The Haswell and Broadwell processors use Advanced Vector Extensions 2 (AVX2) instructions [ ], but from your error message, it seems that you likely have a processor like the Sandy Bridge or Ivy Bridge that does not support the AVX2 instruction set.

So, you will probably have to specify manually what the processor-specific options should be for your system. Refer to the Intel documentation for the version of the Intel compiler that you are using to determine the processor-specific options. For example, if you are using Intel Fortran Compiler 16.0, the User and Reference Guide for it on the Intel website should be at:

Dear Wien2k users,

When installing wien2k at cray system with the following bellow:

I would like to ask you for linking my software using intelfortran and mkl:

O Compiler options: -FR -mp1 -w -prec_div -pc80 -pad -ip -DINTEL_VML -traceback

R R_LIB (LAPACK+BLAS): -lmkl_lapack95_lp64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -openmp -lpthread

But when I tried init_lapw :

with x nn it is fine

when typing
x sgroup

I got this error: Please verify that both the operating system and the processor support Intel(R) MOVBE, FMA, BMI, LZCNT and AVX2 instructions

what is the origine of this error?

Looking forward for your answer.
