From the most recent webinar recordings on Intel ifort and ifx, I realize that ifx automatically enables the OpenMP flag. Does this mean that any software distribution built with ifx requires the Intel runtime environment (for the OpenMP shared files) as well?
In the webinar, Ron mentioned that for ifx -qopenmp-simd is ON by default at –O1 and above. So if you use OpenMP SIMD directives they are automagically used. To disable those, use -qno-openmp-simd.
Similar thing for ifort except -qopenmp-simd is ON by default at –O2 and above.
