Hello, Open MPI retains references to GCC, GFortran, etc., which significantly increases its closure size.
The references come from cpp macros such as OMPI_FC_ABSOLUTE (absolute file name of the Fortran compiler), defined in opal_config.h and returned by command-line tools ‘ompi_info’ and ‘oshmem_info’. What would be the impact of changing these OMPI_*_ABSOLUTE uses to just the basename of the compiler? Are there tools or practices that rely on the info provided by these two commands? Thanks, Ludo’.
