InputParameters
- class ase2sprkkr.input_parameters.input_parameters.InputParameters(definition, inputfile=None, outputfile=False)[source]
It holds the configuration values for a SPR-KKR task and run the task
This class is a ConfigurationContainer, thus, it holds the configuration values for the task. Moreover, according to its definition, it can run the task - execute the executable with proper parameters - and instantiate the result class, which then parse the output of the task.
Class hierarchy

Constructor
- __init__(definition, inputfile=None, outputfile=False)[source]
Create the container and its members, according to the definition
- property task_name
Return the task name, as defined in the definition of the parameters (see InputParametersDefinition class)
- _default_mpi_runner = None
- classmethod default_mpi_runner(auto=False)[source]
- Return the executable and its params to run a mpi task.
The runner is determined by autodetection.
- Parameters
auto (bool) –
- If true,
do not warn if no mpi is found
check the number of available cpus, do not return a runner, if there is only one
- Returns
mpi_runner – List of strings with executable and its parameters to run a mpi task. E.g. [ ‘mpirun’ ] If no suitable runner is found, return False.
- Return type
list or False
- mpi_runner(mpi)[source]
Return a shell command to execute a mpi task.
- Parameters
mpi_runner –
- Returns
mpi_runner – List of strings with the executable and its parameters, e.g.
['mpirun', '-np', '4']
- Return type
list
- is_mpi(mpi=True)[source]
Will be this task (the task described by this input parameters) runned using mpi?
- Parameters
mpi (list or str or bool) – Optional parameter. If False is given, return False regardless the type of the task, otherwise it is ignored. See InputParameters.mpi_runner for the explanation of the parameter.
- Returns
is_mpi – Will be this task runned using mpi?
- Return type
bool
- run_process(calculator, input_file, output_file, print_output=False, executable_postfix=None, mpi=None)[source]
Run the process that calculate the task specified by this input paameters
- calculator: ase2sprkkr.sprkkr.calculator.SPRKKR
Calculator, used for running the task. Various configurations are readed from them.
- input_file: file
File, where the input parameters for the task are stored.
- output_file: file
File, where the output will be writed. It should be opened for writing (in binary mode)
- print_output: bool or str
Print the output to the stdout, too? String value ‘info’ prints only selected infromations (depending on the task runned)
- executable_postfix: str or None
Postfix, appended to the name of the called executable (sometimes, SPRKKR executables are compiled so that the resulting executables has postfixies)
- mpi: list or str or bool
Run the task using mpi? See InputParameters.mpi_runner for the possible values of the parameter.
- Returns
out – The result of ase2sprkkr.common.process_output_reader.ProcessOutputReader.run() method: the parsed output of the runned task.
- Return type
mixed
- result_reader(calculator=None, directory=None)[source]
Return the result readed: the class that parse the output of the runned task
- calculator
Calculator, which will be attached to the resulting class for ruther processing the results
- directory
Directory, to which will be related the relative paths in the result. If none, get the directory from the calculator, or the current directory
- read_output_from_file(filename, directory=None)[source]
Read output of a previously runned task from a file and parse it in a same way, as the process would be runned again.
- filename
Filename, from which the result will be read
- directory
A directory, to which are related the paths in the output Default None means the directory, where the file is
- executable_params(directory=None)[source]
- Return type
([executable], stdin, stdout) params for process.Popen
- definitions = {'ARPES': <ase2sprkkr.input_parameters.input_parameters_definitions.InputParametersDefinition object>, 'DOS': <ase2sprkkr.input_parameters.input_parameters_definitions.InputParametersDefinition object>, 'PHAGEN': <ase2sprkkr.input_parameters.input_parameters_definitions.InputParametersDefinition object>, 'SCF': <ase2sprkkr.input_parameters.input_parameters_definitions.InputParametersDefinition object>}
- classmethod create_input_parameters(arg)[source]
Create input_parameters object
- Parameters
arg (str or InputParameters) – If an InputParameters object is given, it is returned as is. If a string is given, it is interpreted either as a filename (from which the parameters are read) or the task name, for which the default parameters are used
- Returns
input_parameters
- Return type
- classmethod create(name)[source]
Create input parameters for the given task name :param name: Name of the task (e.g. ‘SCF’, ‘PHAGEN’) :type name: str
- Returns
input_parameters – Input parameters with the default values for the given task.
- Return type
- classmethod from_file(filename, allow_dangerous=False)[source]
Read an input file and create a new InputParameters object from the readed stuff
- Parameters
filename (str or file) – Input file (either its filename, or an open file)
allow_dangerous (bool) – Allow to read dangerous values of options: i.e. the values that do not fullfil the required type of the given option or its other requirements.
