The ListMaster is the most simple MetaJob derived from the GenericMaster. It behaves like a Python list object. Jobs can be append to the ListMaster just like elements are added to a list and then all jobs can be executed together. This also works for already executed jobs, unless they are already linked to a different MetaJob - meaning they already have a master ID assigned to them.
- project (ProjectHDFio) – ProjectHDFio instance which points to the HDF5 file the job is stored in
- job_name (str) – name of the job, which has to be unique within the project
.. attribute:: job_name
name of the job, which has to be unique within the project
.. attribute:: status
- execution status of the job, can be one of the following [initialized, appended, created, submitted,
- running, aborted, collect, suspended, refresh, busy, finished]
.. attribute:: job_id
unique id to identify the job in the pyiron database
.. attribute:: parent_id
job id of the predecessor job - the job which was executed before the current one in the current job series
.. attribute:: master_id
job id of the master job - a meta job which groups a series of jobs, which are executed either in parallel or in serial.
.. attribute:: child_ids
list of child job ids - only meta jobs have child jobs - jobs which list the meta job as their master
.. attribute:: project
Project instance the jobs is located in
.. attribute:: project_hdf5
ProjectHDFio instance which points to the HDF5 file the job is stored in
.. attribute:: job_info_str
short string to describe the job by it is job_name and job ID - mainly used for logging
.. attribute:: working_directory
working directory of the job is executed in - outside the HDF5 file
.. attribute:: path
path to the job as a combination of absolute file system path and path within the HDF5 file.
.. attribute:: version
Version of the hamiltonian, which is also the version of the executable unless a custom executable is used.
.. attribute:: executable
Executable used to run the job - usually the path to an external executable.
.. attribute:: library_activated
For job types which offer a Python library pyiron can use the python library instead of an external executable.
.. attribute:: server
Server object to handle the execution environment for the job.
.. attribute:: queue_id
the ID returned from the queuing system - it is most likely not the same as the job ID.
.. attribute:: logger
logger object to monitor the external execution and internal pyiron warnings.
.. attribute:: restart_file_list
list of files which are used to restart the calculation from these files.
.. attribute:: job_type
- Job type object with all the available job types: [‘ExampleJob’, ‘SerialMaster’, ‘ParallelMaster’,
- ‘ScriptJob’, ‘ListMaster’]
.. attribute:: child_names
Dictionary matching the child ID to the child job name.
.. attribute:: submission_status
Monitors how many jobs have been submitted and how many have to be submitted in future.
Append a job to the ListMaster - just like you would append an element to a list.
Parameters: job (JobCore, GenericJob, int) – job to append
Collect output is not implemented for ListMaster jobs
Copy the ListMaster object which links to the job and its HDF5 file
Returns: New ListMaster object pointing to the same job Return type: ListMaster
Check if the ListMaster job is finished - by checking the job status and the submission status.
Returns: [True/False] Return type: bool
Iterate over the jobs within the ListMaster
Parameters: convert_to_object (bool) – load the full GenericJob object (default) or just the HDF5 / JobCore object Returns: Yield of GenericJob or JobCore Return type: yield
Refresh the submission status - if a job ID job_id is set then the submission status is loaded from the database.
Reset the job id sets the job_id to None as well as all connected modules like JobStatus and SubmissionStatus.
run_if_interactive() is not implemented for ListMaster jobs
Internal helper function the run if refresh function is called when the job status is ‘refresh’. If the job was suspended previously, the job is going to be started again, to be continued.
The run static function is called by run to execute the simulation. For the ListMaster this means executing all the childs appened in parallel.
Save the object, by writing the content to the HDF5 file and storing an entry in the database.
Returns: Job ID stored in the database Return type: (int)
This function enforces read-only mode for the input classes, but it has to be implement in the individual classes.
Write the input files - for the ListMaster this only contains the execution mode, which is ‘parallel’ by default.
