So far, under Linux the compiler of the
Portland Group
has been used mostly to compile CO5BOLD.
It is called with pgf90.
Important switches are:
-byteswapio: With this flag set, binary files in
big_endian format
(the standard for UIO files)
are automatically transformed to
little_endian
and vice versa.
-fast: General optimization flag to choose (close to)
optimum optimization for local machine.
-Mvect=sse: Optimization: Allow Pentium III vector commands.
-Mcache_align: Optimization: Align some data object
on cache-line boundaries.
-fastsse: From compiler version 4.0 on, this option can be used instead
of the three previous ones. It contains and supersedes them.
-Minline=...: Optimization: the routines that should be
inlined are listed in Sect. 3.8.2.
-DMSrad_raytas=2: Optimization: choose non-default version
of loop in SUBROUTINE raytas in file MSrad3D.F90.
See Sect. 3.7.
-Drhd_hyd_roe1d_l01=0: Optimization: choose standard set of routines for
Roe solver.
See Sect. 3.7.
-Drhd_shortrad_operator_l02=1: Optimization: use the ``manually inlined
version'' of the short characteristics operator.
-Drhd_shortrad_dtauop_l02=1: Optimization: use the ``manually inlined
version'' of the optical coupling operator.
Everything compiles. The MSrad radiation transport module does not work with OpenMP activated. In this case it is recommended to use the Intel compiler instead (see Sect. 3.8.10).
