The full benchmark run is a run of 5-days using the GMAO Ops setup. This will use space and cores. For effective benchmarking of I/O, it's recommended to run on less congested than nobackup.

These echos set up some defaults. While they both don't have to be in the same location, it's highly recommended they are and the use of the script below assumes they are. Also, make sure they are in a nobackup directory.

To actually create the experiment, run the create_expy.py and choose a C720 horizontal resolution with OPS emissions:
For the next few commands, you will need to know the location of the portable BCs directory used for this experiment, which is referred to below as <tt>$PORTBCS</tt>. On discover, a version will always be at:


  $ ~mathomp4/bin/create_expt.py benchmark-GEOSadas-5_16-5-5day-c720-OpsHistory --horz c720 --ocean o3 --emission OPS --account <ACCOUNTID> --expdir <root-for-experiment>
/discover/nobackup/mathomp4/HugeBCs-H50
 
To create the experiment, run create_expt.py and choose a C720 horizontal resolution with climatological GOCART:
 
  $ $PORTBCS/scripts/create_expt.py benchmark-GEOSadas-5_16-5-5day-c720-Portable --horz c720 --ocean o3 --gocart C --account <ACCOUNTID> --expdir <root-for-experiment>

Now ''change to the experiment directory'' and run makeoneday.bash to create it with Ops like options:
Now ''change to the experiment directory'' and run MakeSBUBench.bash which will set up the experiment:


  $ ~mathomp4/bin/makeoneday.bash opsb
  $ $PORTBCS/scripts/MakeSBUBench.bash


The <tt>opsb</tt> option sets up many things. The run is set for 5 days using 5400 cores, and other flags are tripped to best emulate Ops. It also copies in the Ops HISTORY.rc setup.
The script sets the run up for 5 days using 5400 cores, and other flags are tripped to best emulate Ops.
