process_signals() int pism::IceModel::process_signals ( ) protectedvirtual Catch signals -USR1, -USR2 and -TERM. Signal SIGTERM makes PISM end, saving state under original -o name (or default name). We also add an indication to the history attribute of the output NetCDF file. Signal SIGUSR1 makes PISM save state under a filename based on the the name of the executable (e.g. pismr or pismv) and the current model year. In addition the time series (-ts_file, etc.) is flushed out There is no indication of these actions in the history attribute of the output (-o) NetCDF file because there is no effect on it, but there is an indication at stdout. Signal SIGUSR2 makes PISM flush time-series, without saving model state. Definition at line 47 of file utilities.cc.
