  • in_dir (str) –

  • out_dir (str) –

orders()

List of supported Orders in this runner.

Return type:

List[hepi.input.Order]

get_name()

Returns the name of the runner.

Return type:

str

get_version()
Return type:

str

_sub_run(coms)
Parameters:

coms (List[str]) –

Return type:

str

_check_path()

Checks if the passed path is valid.

Return type:

bool

_prepare(p, skip=False, assume_valid=False, **kwargs)
Parameters:

p (hepi.input.Input) –

Return type:

RunParam

_check_input(param, **kwargs)
Parameters:

param (hepi.input.Input) –

Return type:

bool

_prepare_all(params, skip=True, n_jobs=None, **kwargs)

Prepares all parameters for execution.

Parameters:

  • params (List[hepi.Input]) – List of input parameters.

  • skip (bool, optional) – If True, the runner will check if the output file already exists and skip the execution if it does. Defaults to True.

  • n_jobs (int) – Number of parallel jobs. If None, use all available cores.

Return type:

List[RunParam]

run(params, skip=True, parse=True, parallel=True, sleep=0, run=True, ignore_error=False, n_jobs=None, **kwargs)

Run the passed list of parameters.

Args:

params (list of hepi.Input): All parameters that should be executed/queued. skip (bool): True means stored runs will be skipped. Else the are overwritten. parse (bool): Parse the results.

This is not the prefered cluster/parallel mode, as there the function only queues the job.

parallel (bool): Run jobs in parallel. sleep (int): Sleep seconds after starting job.

run (bool): Actually start/queue runner. ignore_error (bool): Continue instead of raising Exceptions. Also ignores hash collisions. n_jobs (int): Number of parallel jobs. If None, use all available cores.

Returns:

pd.DataFrame : combined dataframe of results and parameters. The dataframe is empty if parse is set to False.

Parameters:

params (List[hepi.input.Input]) –

_run(rps, wait=True, parallel=True, sleep=0, n_jobs=None, **kwargs)

Runs Runner per RunParams.

Args:

rps (list of RunParams): Extended run parameters. bar (bool): Enable info bar. wait (bool): Wait for parallel runs to finish. sleep (int): Sleep seconds after starting subprocess. parallel (bool): Run jobs in parallel.

n_jobs (int): Number of parallel jobs. If None, use all available cores.

Returns:

list of int: return codes from jobs if no_parse is False.

Parameters:

rps (List[RunParam]) –

_is_valid(file, p, d, **kwargs)

Verifies that a file is a complete output.

Parameters:

  • file (str) – File path to be parsed.

  • p (hepi.Input) – Onput parameters.

  • d (dict) – Param dictionary.

Returns:

True if file could be parsed.

Return type:

bool

parse(outputs, n_jobs=None)

Parses Resummino output files and returns List of Results.

Args:

outputs (list of str): List of the filenames to be parsed.

n_jobs (int): Number of parallel jobs. If None, use all available cores.

Returns:

list of hepi.resummino.result.ResumminoResult

Parameters:

outputs (List[str]) –

Return type:

List[hepi.results.Result]

_parse_file(file)

Extracts results from an output file.

Parameters:

file (str) – File path to be parsed.

Returns:

If a value is not found in the file None is used.

get_output_dir()

Get the input directory.

Returns:

out_dir

Return type:

get_pre()

Gets the command prefix.

Returns:

pre

Return type:
