schrodinger.application.matsci.jaguarworkflows module

Workflow and Step classes to aid in running a series of Jaguar jobs.

For each molecule, a Workflow object is established. The Steps the Workflow will run depend on the options chosen. Some Steps depend on other Steps to finish before starting. It is the job of the Workflow to submit jobs when all the required dependencies have finished successfully.

Workflow objects submit jobs to a JobDJ queue.

class schrodinger.application.matsci.jaguarworkflows.Results(path)

Bases: object

A low memory results object - because the driver ends up holding on to results for a long time and can be simultaneously holding results for a large number of calculations, we want to keep the memory footprint of each result low. Mainly, we don’t want to hold structures in memory, but also orbital eigenvectors, etc.

This class mimics a limited subset of the jaguar.output.JaguarResults class API. Future needs might increase which properties are kept, but do not keep any large-memory properties.

__init__(path)

Create a Results object.

path (str) – path to the Jaguar Output file, or a path to the input file, as the JaguarOutput class can find the output file from that.

Any job may be submitted by the Workflow to the Queue as long as the jobs above it on its branch of the tree have completed successfully.

FALLBACK_BASE_NAME = 'structure'
__init__(struct, options, count, jobq, strcleaner=None, logger=None, subhierarchy=None, robust=False, max_retries=None)

Create a Workflow object

Parameters

  • struct (schrodinger.structure.Structure) – The initial structure to use for the workflow

  • options (argparse Namespace object) – The input options.

  • count (int) – A serial number to distinguish this workflow from other workflows. May be used to create a unique base name.

  • jobq (JobDJ) – The queue to submit jobs to

  • strcleaner (schrodinger.application.matsci.jobutils.StringCleaner or None) – A StringCleaner instance used to guarantee unique workflow base names

  • logger (logging.Logger) – The logger for this class

  • subhierarchy (str) – If given, the final structure for all steps other than the main step will be placed in a PT subgroup with this name.

  • robust (bool) – If True, use the robust Jaguar driver to run Jaguar jobs. If false, use Jaguar directly.

  • max_retries (int or None) – see queue.JobControlJob

generateBaseName(strcleaner, count)

Come up with a base name for this workflow based on the workflow structure title or a fallback name if the title can’t be used. Pass in a StringCleaner object to guarantee uniqueness.

Parameters
log(msg, prefix=True, level=20, pad=False, pad_below=False)

Add a message to the log file

Parameters

  • msg (str) – The message to add

  • prefix (bool) – Whether to add information about the workflow and step name to the front of the message string

  • level (int) – A logging constant indicating the priority level of the message

  • pad (bool) – Whether to pad above this message with a blank line

  • pad_below (bool) – Whether to pad below this message with a blank line

getSteps()

Create all the steps required for this workflow

This method should almost certainly be overridden by any child class. The example given here is just that - an example

periodicMaintenance()

The run_workflows function will call this method periodically - it can be used to perform operations while one of the workflow steps is running

check(log_zero_steps=False)

Check if this workflow is complete. Also, submit the next step(s) if the previous step has finished.

Parameters

log_zero_steps (bool) – log a message if there are zero steps

Return type

bool

Returns

True if the workflow is complete, False if not

recordFailureStatus()

Set properties based on the success/failure of each step, and write workflow structures to a summary failed file if any step failed

write(writer)

Write out the structure for this workflow and all the child structures

Parameters

writer (schrodinger.StructureWriter) – The writer to use to write the structure

stepsInWriteOrder()

Generator for steps in the order they’re output structures should be written to the results file. Main step first, then all other steps in order of creation.

Return type

iterator

Returns

iterator of step objects

schrodinger.application.matsci.jaguarworkflows.run_workflows(jobq, active_workflows, writer)

Run all the workflows and return when they are finished. At the end of this function, active_workflows will be empty. Returns True if at least one job did not fail (or there were no jobs to run), otherwise False.

Parameters
Return type

bool

Returns

True if at least one job did not fail, otherwise False

schrodinger.application.matsci.jaguarworkflows.parse_matrix(out_file)

Parse a matrix from a jaguar output file

Parameters

out_file (iterable) – An iterable such as the file handle. Should be at the beginning of the matrix part of the file.

Return type

numpy.array

Returns

Numpy array containing the correlation matrix

Change the Jaguar file link properties to point to the original job directory instead of the subjob directory. If not running under job control, the current working directory is used as the original job directory.

Parameters
schrodinger.application.matsci.jaguarworkflows.get_delta_energy(reactants, products)

Compute delta energy as: dE = E(Products) - E(Reactants) in kcal/mol

Parameters
Return type

float

Returns

Energy in kcal/mol
