Optionally this may also be used to trigger this module's end routine. day The current model time. n The time step number of the current execution. cs The control structure set up by a previous call to MOM_write_cputime_init. nmax The number of iterations after which to stop so that the simulation will not run out of CPU time. call_end If true, also call MOM_write_cputime_end. clocks_per_sec mom_error_handler::is_root_pe max_ticks mom_error_handler::mom_error mom_write_cputime_end mom_main A module to monitor the overall CPU time used by MOM6 and project when to stop the model. By Robert Hallberg, May 2006. This file contains the subroutine (write_cputime) that writes the summed CPU time across all processors to an output file. In addition, write_cputime estimates how many more time steps can be taken before 95% of the available CPU time is used, so that the model can be checkpointed at that time.
