Description of the standard output

New page

ROMS writes to the standard output, unit 6 by default. It writes a very complete set of diagnostics on startup so that you can check to make sure everything is in order. An example of this output for the BENCHMARK option is below. I will attempt to describe each section here, but it's a wiki, so fix what's wrong:

Node # 3 (pid= 13402) is active.

Some timing statistics produced by ROMS internally. Some of its percentages are a little odd for parallel runs, but they should make sense for serial runs. Note that the 2D engine is significant. Also note that we've turned off writing of NetCDF files for this case - realistic problems spend a significant fraction in the I/O.
