While you can set /QxAVX , the CPU dispatcher in 11.1 does not recognize modern AVX2 (Haswell+) or AVX-512. It will fall back to SSE4.2. Use explicit architecture flags rather than auto-dispatch.
On Windows 8+, the linker may throw LNK1123: failure during conversion to COFF . Replace the cvtres.exe in your VS 2008/bin folder with a version from VS 2010 or disable incremental linking ( /INCREMENTAL:NO ). While you can set /QxAVX , the CPU dispatcher in 11
Uses execution data to reorganize code for better cache usage and reduced branch mispredictions. On Windows 8+, the linker may throw LNK1123:

While modern compilers support Fortran 2018, version 11.1 was a major leap because it fully implemented the Fortran 2003 standard. Key features include:
For organizations still relying on 11.1.051, common issues often arise from:
