3.5.4 Hitachi

• -conti199: Up to 199 continuation lines can be interpreted (otherwise not more than 39 continuation lines are accepted).

• -limit: Limits the amount of time and memory for compilation.

• -opt=ss: use highest possible optimization level.

• -nopredicate: this option switches off a sub-option activated by opt=ss. It is necessary to disable the -predicate option because the code crashes otherwise (segmentation violation). The switch must appear after setting -opt=ss.

• -pvfunc=2: References the pseudo-vectorizing mathematical function and applies the temporary array to reference the pseudo-vectorizing mathematical function.

• -omp -parallel=1: parallelize based on OpenMP directives only.

• -orphaned=1: Checks if the regions sequentially executed contain orphaned directives during run-time when PROCNUM=8 is specified. If a sequentially executed region contains an orphaned directive, the system outputs a message and terminates the program.

• -nestcheck=1: Checks for nesting errors in parallel regions. If a parallel region is nested, the system returns an error and terminates the program. Without this option, the code aborts with an error message, indicating illegal nesting. Compiler bug?

• -procnum=8: generated code for 8 processors on one node

• -pmpar: Collects the performance monitor information for each parallelization unit.

• -pmfunc: Collects the performance monitor information for each procedure.

• -Drhd_hyd_roe1d_l01=1: Optimization: Choose non-standard set of routines for Roe solver. See Sect. 3.4.

• -DMSrad_raytas1: Optimization: choose non-default version of SUBROUTINE raytas in file MSrad3D.F90.

• Important note: The UIO routines need in addition the compiler option -subchk: Array bound checking. Without this checking option, some UIO routines are not working properly (compiler bug?).
