pegasus-run — executes a workflow that has been planned using *pegasus-plan*.


pegasus-run [-Dproperty=value…][-c propsfile][-d level]


The pegasus-run command executes a workflow that has been planned using pegasus-plan. By default pegasus-run can be invoked either in the planned directory with no options and arguments or just the full path to the run directory. pegasus-run also can be used to resubmit a failed workflow by running the same command again.


By default pegasus-run does not require any options or arguments if invoked from within the planned workflow directory. If running the command outside the workflow directory then a full path to the workflow directory needs to be specified.

pegasus-run takes the following options


The -D option allows an advanced user to override certain properties which influence pegasus-run. One may set several CLI properties by giving this option multiple times.

The -D option(s) must be the first option on the command line. CLI properties take precedence over the file-based properties of the same key.

See the PROPERTIES section below.

-c propsfile , --conf propsfile
Provide a property file to override the default Pegasus properties file from the planning directory. Ordinary users do not need to use this option unless the specifically want to override several properties
-d level , --debug level
Set the debug level for the client. Default is 0.
-v , --verbose
Raises debug level. Each invocation increase the level by 1.
Enable grid checks to see if your submit machine is GRID enabled.
Is the full qualified path to the base directory containing the planned workflow DAG and submit files. This is optional if the pegasus-run command is invoked from within the run directory.

Return Value

If the workflow is submitted for execution pegasus-run returns with an exit code of 0. However, in case of error, a non-zero return value indicates problems. An error message clearly marks the cause.


The following files are created, opened or written to:

This file is located in the rundir. pegasus-run uses this file to find out paths to several other files, properties configurations etc.
This file is located in the rundir. pegasus-run uses this properties file by default to configure its internal settings.
pegasus-run uses the workflowname.dag or file and submits it either to condor for execution or runs it locally in a shell environment


pegasus-run reads its properties from several locations.

The default location for pegasus-run to read the properties from
--conf propfile
properties file provided in the conf option replaces the default properties file used.

will be used if neither default rundir properties or --conf propertiesfile are found.

Additionally properties can be provided individually using the -Dpropkey=propvalue option on the command line before all other options. These properties will override properties provided using either --conf or RUNDIR/pegasus.???????.properties or the $HOME/.pegasusrc

The merge logic is CONF PROPERTIES || DEFAULT RUNDIR PROPERTIES || PEGASUSRC overriden by Command line properties

Environment Variables

The path variable is used to locate binaries for condor-submit-dag, condor-dagman, condor-submit,pegasus-submit-dag, pegasus-dagman and pegasus-monitord
