[Wien] OS and processor instruction error

[Gavin Abo]

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 [ 
http://www.nas.nasa.gov/hecc/support/kb/recommended-compiler-options_99.html 
], 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:
