Printed Output

The printed output of the code is found in the file pccm.out.0000. The suffix indicates that the file is written from processor (0,0) of the logical mesh. It consists of version information, the namelist input summary which controls the simulation, a listing for each step the program executed giving

RMSZ

global RMS vorticity,

RMSD

global RMS divergence,

RMST

global RMS temperature,

STPS

global mass integral,

STQ

global moisture integral,

COUR

maximum Courant number for horizontal velocity field.

Also included in the printed output is information about the contents of history tapes written at each history tape output. Finally, the ``END OF MODEL RUN'' message is printed with summary information.

The other print file generated by the PCCM2 code is pccm.error.0000. Error messages to unit 0, the standard error unit, are included in this file. Also timing information for each time step is included if the INTERVAL_TIMER has been enabled.

Both the pccm.out.0000 and pccm.error.0000 files are output from processor (0,0) of the logical processor mesh. Output from other processors is sent to /dev/null and is therefore unavailable. It has been found that opening output files on every processor will crash or hang many MPP systems. For debugging purposes, this option is still included as a compile time option, but is not supported in the standard configuration.
