With Version 7.0 of the Intel compiler CO5BOLD (with the SHORTrad module only, so far) compiles.
The native format on Intel machines is
little_endian.
With
export F_UFMTENDIAN=big
the default can be changed to
big_endian.
The appropriate UIO modules are uio_mac_intel_module.f90 in the little_endian
case and uio_mac_sun_module.f90 in the big_endian case.
The compiler is called with ifc.
Important switches are:
-Vaxlib: Link proper library to make the machine understand
e.g. call flush(6).
fpp: Activate the preprocessor (silently).
-O3: General optimization flag.
-tpp6 -xK: Optimization especially for Pentium III
(includes SSE vector commands).
-ip: Optimization: activate interprocedural optimization within
each source file. This enables inlining.
-Drhd_shortrad_dir1_l01=1: Optimization:
Transpose arrays and use routine rhd_shortrad_dir3 for rays in x1 direction.
See Sect. 3.7.
-openmp: Parallelization: OpenMP directive are activated. Note that the
UIO routines should be compiled without OpenMP support (even if they do not contain
any OpenMP directives themselfes).
