The 12-processor machine ``zeipel'' from Hewlett-Packard is a ``V2500 PA 2.0'' system. Yet, there is no success to make it accept all the OpenMP directives in COBOLD (and to run COBOLD in parallel mode). And the single-processor performance is mediocre. Some macros, which seem to be necessary:
+U77
: Link proper library to make the machine understand
e.g. call flush(6)
.
+cpp=yes
: Switch on the C preprocessor. Note that all Fortran90 files have to
end with ``.f90''. The ``.F90'' suffix does not seem to work.
+Oparallel +Oopenmp +Onoautopar
: Try to enable parallelization with
OpenMP directives, disable auto-parallelization. Does not work!
+Onoinline
: Disable inlining. That's too complicated.
+O3 +Olimit
: General optimization with limited resource usage
during compilation.
