To launch the workflow, first ensure that you have a compatible version
of rocoto available. For most pre-configured platforms, rocoto can be
loaded via a module:
> module load rocoto
For more details on rocoto, see the User's Guide.
To launch the workflow, first ensure that you have a compatible version
of rocoto loaded. For example, to load version 1.3.1 of rocoto, use
> module load rocoto/1.3.1
(This version has been tested on hera; later versions may also work but
have not been tested.)
To launch the workflow, change location to the experiment directory
(EXPTDIR) and issue the rocotrun command, as follows:
> cd {EXPTDIR}
> {rocotorun_cmd}
To check on the status of the workflow, issue the rocotostat command
(also from the experiment directory):
> {rocotostat_cmd}
Note that:
1) The rocotorun command must be issued after the completion of each
task in the workflow in order for the workflow to submit the next
task(s) to the queue.
2) In order for the output of the rocotostat command to be up-to-date,
the rocotorun command must be issued immediately before issuing the
rocotostat command.
