Command Line Interface (CLI) for WRF4G
wrf4g_framework
Usage
wrf4g_framework {start|stop|restart|reload|status}
Synopsis
wrf4g_framework manages WRF4G framework components: GridWay and MySQL (in case it is needed). It loads the framework configuration from $WRF4G_LOCATION/etc/framework4g.conf.
wrf4g_prepare
Usage
wrf4g_prepare [--dry-run] [--reconfigure] [--verbose] [--help]
Synopsis
Given a file (experiment.wrf4g) describing the experiment, prepare it by creating the realization and chunks needed to perform the experiment.
Options
--dry-run Perform a trial run with no changes made.
--reconfigure Reconfigure experiment. With this option we can change the start and end date of the experiments
and add new physics. Values are taken from a modified experiment.wrf4g.
--verbose Verbose mode. Explain what is being done
--help Shows this help
wrf4g_submit
Usage
wrf4g_submit [--dry-run] [--{exp Experiment|rea Realization|frea File|chunk ChunK|nchunk Number_of_chunks|nrea Number_of_realizations}] [--rerun] [--run-just-one][--priority P] [--verbose] [--force] [--tdep afterok | afternotok | afterany] [--help]
Synopsis
Submit an experiment or a realization. If the user doesn't specify an experiment or a realization with the options, the name of the experiment will be retrieved from experiment.wrf4g in case it exists in the current folder.
Options
--version show program's version number and exit
-h, --help show this help message and exit
-n, --dry-run Perform a trial run with no changes made
-e name, --exp=name Name of the experiment to submit
-r name, --rea=name Name of the realization to submit
-F FILE, --frea=FILE File containing the name of the realization to submit.
-a, --rerun Force to run although the realization or experiment
has finished
-o, --run-just-one Run just the first chunk of the first realization.
Only for testing purposes.
-C N, --nchunk=N Run the next N chunks not finished of each realization
-R N, --nrea=N Run the next N realizations not finished of the
experiment
-p P, --priority=P P is the priority of the experiment or realization that is
going to be launched (P is an integer between 0 and 20)
-v, --verbose Verbose mode. It explains what is being done
-f, --force Don't ask the user if he wants to submit an experiment
already submitted
-d TYPE_DEP, --tdep=TYPE_DEP
Specify dependencies between Chunks. afterok: The
chunk may be scheduled for execution only after jobs
jobid have finished without any error. afternotok: The
chunk may be scheduled for execution only after jobs
jobid have finished with errors. afterany: The chunk
may be scheduled for execution after jobs jobid have
finished, with or without errors.
wrf4g_status
Usage
wrf4g_status [--{exp Experiment|rea Realization}] [--long] [--ncharacters N] [--help]
Synopsis
Print the experiment or realization status.
Options
--version show program's version number and exit
-h, --help show this help message and exit
-e name, --exp=name Name of the experiment.
-r name, --rea=name Name of the realization
-l, --long Show a detailed status.
-n NUMBER_OF_CHARACTERS, --ncharacters=NUMBER_OF_CHARACTERS
Print n characters of the Experiment's name
(default value is 20 characters)
Output field description
Summarized output: Shows realizations' status of each experiment (Default).

- Realization: Realization name.
- Status: It can take the following values: P(Prepared), S(Submitted), R(Running), F(Failed) and D(Done).
- Chunks [Chunk currently running/Total Chunks]: A realization is split into chunks. Each chunk is sent as a job.
- Computer resource: Computing Resource where the job is running. (It has to be one of the resources listed by wrf4g_resources)
- WN: Computing node where the job is running.
- Run.Sta: Job status in the WN (Downloading data, running ungrib, real, wrf, ...)
- ext: Exit Code. If exit code is different from 0, there has been an error. Error codes are explained in $WRF4G_LOCATION/lib/bash/wrf4g_exit_codes.sh
- % : percentage of simulation finished.
wrf4g_resources
Usage
wrf4g_resources [-h] [-c delay] [-nfx] [-m job_id] [host_id]
Synopsis
Print information about all the resources configured in framework4g.conf (default)
Options
-h print this help -c delay refresh host information every delay seconds -n do not print the header -f full format -x xml format -m job_id print hosts matching the requirements of a given job host_id only monitor this host_id, printing also queue information

wrf4g_priority
Usage
wrf4g_priority [--dry-run] [--{exp Experiment |rea Realization |frea File}] [--priority P] [--verbose] [--help]
Synopsys
Change the priority of an experiment/realization. The priority must be in range [0,20] and default value is 0. When a chunk gets a priority of 20, it becomes urgent. This chunk is dispatched as soon as possible, passing all the scheduling policies.
Options
--version show program's version number and exit
-h, --help show this help message and exit
-n, --dry-run Perform a trial run with no changes made
-e name, --exp=name Name of the experiment
-r name, --rea=name Name of the realization
-F FILE, --frea=FILE File containing the name of the realization to change
the priority
-v, --verbose Verbose mode. Explain what is being done
-p PRIORITY, --priority=PRIORITY
The priority must be in range [0,20].
wrf4g_kill
Usage
wrf4g_kill [--dry-run] [--{exp Experiment |rea Realization|frea File}] [--verbose] [--help]
Synopsys
wrf4g_kill command kill the jobs that belong to an experiment or realization. Additionally, the experiment and realization ckunks, which have not done, will go back to "Prepared" status
Options
--version show program's version number and exit -h, --help show this help message and exit -n, --dry-run Perform a trial run with no changes made -e name, --exp=name Name of the experiment -r name, --rea=name Name of the realization -F FILE, --frea=FILE File containing the name of the realization -v, --verbose Verbose mode. Explain what is being done.
