Checking Job Generation

Job generation involves the following processes:

  • Locating the ‘.ecf’ files

  • Locating the includes files specified in the ‘.ecf’ file

  • Removing comment and manual pre-processor statements

  • Variable substitution

  • Creating the job file on disk

This is what the ecflow_server does when submitting your task/job.

This process can be checked BEFORE loading the suite to the server, by using the Python API. Since this API is used for checking, the jobs are all generated with the extension ‘.job0’. The following example checks job generation fo all tasks.

Listing 103 Default
defs = ecflow.Defs("my.def")  # load file 'my.def' into memory, not needed if the defs was created in python
msg = defs.check_job_creation()  # job files generated to ECF_JOB
print(msg)

For brevity, the following examples do not show how the ‘defs’ object was created. This can be read in from disk as shown above or created directly in python.

Listing 104 Checking of job generation for all tasks under ‘/suite/to_check’
job_ctrl = ecflow.JobGenCtrl()
job_ctrl.set_node_path("/suite/to_check")  # hierarchical job generation under /suite/to_check
defs.check_job_generation(job_ctrl)  # do the check
print(job_ctrl.get_error_msg())

This example shows the checking of job generation for all tasks, but where the jobs are generated to a user-specified directory. i.e. ‘/tmp/ECF_NAME.job0’.

Listing 105 Generated jobs to a user specified directory
job_ctrl = ecflow.JobGenCtrl()
job_ctrl.set_dir_for_job_generation("/tmp")  # generate jobs file under this directory
defs.check_job_generation(job_ctrl)  # do the check
print(job_ctrl.get_error_msg())  # report any errors in job generation

This example show job checking to an automatically generated temporary directory $TMPDIR/ecf_check_job_generation/ECF_NAME.job0

Listing 106 Generate temporary directory
job_ctrl = ecflow.JobGenCtrl()
job_ctrl.generate_temp_dir()
defs.check_job_generation(job_ctrl)
print(job_ctrl.get_error_msg())
