Build options:

  • dmpar (MPI with OpenMPI)
  • NetCDF serial with HDF5 compression

Variants:

  • ccub_fcoptim = local optimizations (-Ofast -ffast-math -ftree-vectorize -funroll-loops -mieee-fp)
  • ccub_ghg = include greenhouse gases emissions (default in versions from 4.4)
  • ccub_no_leap = without leap years (every year has 365 days)
  • pnetcdf = Parallel IO support through Pnetcdf library
