aiida.orm.nodes.process.process.ProcessNodeLinks
Interface for links of a node instance.
- __annotations__ = {}#
- __module__ = 'aiida.orm.nodes.process.calculation.calcfunction'#
- validate_outgoing(target: Node, link_type: aiida.common.links.LinkType, link_label: str) None [source]#
Validate adding a link of the given type from ourself to a given node.
A calcfunction cannot return Data, so if we receive an outgoing link to a stored Data node, that means the user created a Data node within our function body and stored it themselves or they are returning an input node. The latter use case is reserved for @workfunctions, as they can have RETURN links.
- Parameters
target – the node to which the link is going
link_type – the link type
link_label – the link label
- Raises
TypeError – if target is not a Node instance or link_type is not a LinkType enum
ValueError – if the proposed link is invalid

- static _validate_retrieval_directive(directives: Sequence[Union[str, Tuple[str, str, str]]]) None [source]#
Validate a list or tuple of file retrieval directives.
- Parameters
directives – a list or tuple of file retrieval directives
- Raises
ValueError – if the format of the directives is invalid
- get_authinfo() AuthInfo [source]#
Return the AuthInfo that is configured for the Computer set for this node.
- Returns
AuthInfo
- get_detailed_job_info() Optional[dict] [source]#
Return the detailed job info dictionary.
The scheduler is polled for the detailed job info after the job is completed and ready to be retrieved.

Return job id that was assigned to the calculation by the scheduler.
- Returns
the string representation of the scheduler job id
- get_last_job_info() Optional[JobInfo] [source]#
Return the last information asked to the scheduler about the status of the job.
The last job info is updated on every poll of the scheduler, except for the final poll when the job drops from the scheduler’s job queue. For completed jobs, the last job info therefore contains the “second-to-last” job info that still shows the job as running. Please use
get_detailed_job_info()
instead.- Returns
a JobInfo object (that closely resembles a dictionary) or None.
- get_option(name: str) Optional[Any] [source]#
Retun the value of an option that was set for this CalcJobNode

Return the path to the remote (on cluster) scratch folder of the calculation.
- Returns
a string with the remote path
- get_retrieve_list() Optional[Sequence[Union[str, Tuple[str, str, str]]]] [source]#

Return the scheduler stderr output if the calculation has finished and been retrieved, None otherwise.
- Returns
scheduler stderr output or None
- get_state() Optional[aiida.common.datastructures.CalcJobState] [source]#
Return the calculation job active sub state.
The calculation job state serves to give more granular state information to CalcJobs, in addition to the generic process state, while the calculation job is active. The state can take values from the enumeration defined in aiida.common.datastructures.CalcJobState and can be used to query for calculation jobs in specific active states.
- Returns
instance of aiida.common.datastructures.CalcJobState or None if invalid value, or not set
- get_transport() Transport [source]#
Return the transport for this calculation.
- Returns
Transport configured with the AuthInfo associated to the computer of this node

Return whether the calculation job was imported instead of being an actual run.
- property res: CalcJobResultManager#
To be used to get direct access to the parsed parameters.
- Returns
an instance of the CalcJobResultManager.
- Note
a practical example on how it is meant to be used: let’s say that there is a key ‘energy’ in the dictionary of the parsed results which contains a list of floats. The command calc.res.energy will return such a list.
- set_detailed_job_info(detailed_job_info: Optional[dict]) None [source]#
Set the detailed job info dictionary.
- Parameters
detailed_job_info – a dictionary with metadata with the accounting of a completed job

- property tools: CalculationTools#
Return the calculation tools that are registered for the process type associated with this calculation.
If the entry point name stored in the process_type of the CalcJobNode has an accompanying entry point in the aiida.tools.calculations entry point category, it will attempt to load the entry point and instantiate it passing the node to the constructor. If the entry point does not exist, cannot be resolved or loaded, a warning will be logged and the base CalculationTools class will be instantiated and returned.

CalculationTools instance
- class aiida.orm.nodes.process.calculation.calcjob.CalcJobNodeCaching(node: Node)[source]#
Bases:
aiida.orm.nodes.process.process.ProcessNodeCaching
Interface to control caching of a node instance.
- __annotations__ = {}#
- __module__ = 'aiida.orm.nodes.process.calculation.calcjob'#
- _get_objects_to_hash() List[Any] [source]#
Return a list of objects which should be included in the hash.
This method is purposefully overridden from the base Node class, because we do not want to include the repository folder in the hash. The reason is that the hash of this node is computed in the store method, at which point the input files that will be stored in the repository have not yet been generated. Including these anyway in the computation of the hash would mean that the hash of the node would change as soon as the process has started and the input files have been written to the repository.
