These are flags that appear in the benchmark sources, categorized as to whether they are portability candidates, mandatory, or forbidden.

Portability Flags

- -DSPEC_NO_ISO_FORTRAN_ENV
- (?:^|(?<=\s))[-/]DSPEC_NO_ISO_FORTRAN_ENV(?:$[^$]+\))?(?:=\S*)?(?=\s|$)
- Set this if your Fortran compiler does not provide the iso_fortran_env standard intrinsic module

- -DSPEC_MPI
- (?:^|(?<=\s))[-/]DSPEC_MPI(?:$[^$]+\))?(?:=\S*)?(?=\s|$)
- This macro is defined when the benchmark is built with MPI threading. MPI is not a supported threading model for this SPEC CPU benchmark, and the SPEC_MPI flag is forbidden.
- -DINTERNAL_TIMING
- (?:^|(?<=\s))[-/]DINTERNAL_TIMING(?:$[^$]+\))?(?:=\S*)?(?=\s|$)
- This macro enables some timing code which also requires MPI. It may not be set for SPEC CPU runs.
- -D_OPENMP
- (?:^|(?<=\s))[-/]D_OPENMP(?:$[^$]+\))?(?:=\S*)?(?=\s|$)
- This macro may be set by the compilation system when building the speed version of the benchmark with OpenMP parallelization. It may not be set explicitly.
