  Hi 

  The attached file fails with an internal error with the following compile flags

 icpc --version

 OS RHEL 6.4

 Thanks

Are you expecting this to generate both avx512 and Mic knc code, choosing at run time?  even if a documented feature it might not be implemented yet.  I did get a partial response about making premier.intel.com accept a beta issue. Yes, it should give a better response if unable to execute.

Hi Tim

Yes this is a snippet of a code that uses auto dispatch to compile both code paths and to choose at runtime. The compiler does not fail if you remove the -opt-report option.
