Steps for use in Workflows

Bases: tuple

names¶: Alias for field number 1

outfiles¶: Alias for field number 2

subdirs¶: Alias for field number 0

exception schrodinger.application.matsci.jwsteps.JobCreationError¶

Bases: Exception

Raised when a job cannot be created

class schrodinger.application.matsci.jwsteps.BaseWorkflow(struct, options, count, jobq, strcleaner=None, logger=None, subhierarchy=None, robust=False, max_retries=None)¶

Bases: WorkFlow

Base Workflow class

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

write(writer, *args, **kwargs)¶

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

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

writeSmap(filename)¶

Write smap files for steps that need them and the smap file for the entire job

Parameters:: filename (str) – The name of the output structure file
Return type:: str or None
Returns:: The name of the written smap file or None if no file written

class schrodinger.application.matsci.jwsteps.SubdirectoryStepMixin(*args, **kwargs)¶

Bases: object

A mixin to handle some common functionality for steps that run in subdirectories

__init__(*args, **kwargs)¶: See parent class for documentation

finishProcessingJobControlJob()¶: Add all the subjob files to the backend

setSubDir()¶: Determine the absolute path to this step’s subdirectory so that we can always access it no matter what the current directory is

class schrodinger.application.matsci.jwsteps.BaseStep(*args, procs=1, tag=None, flags=None, archive=False, monitor_globs=None, full_command=None, local_files=None, input_file=None, cpu_hostname=None, gpu_hostname=None, umbrella='per_flag', splitter=False, split_index=1, split_tag='', child_stages=None, use_jc=None, tpp=1, **kwargs)¶

Bases: SubdirectoryStepMixin, Step

A base class for Steps that are not simple Jaguar jobs. Because this step fires off a Python script that itself fires off Jaguar jobs, we have to modify a number of methods that dealt with the jaguar .in file directly or expected standard Jaguar output.

Create a BaseStep object

Parameters:

procs (int) – The number of processors to allocate to steps of this class
tag – str(tag) will be added to the end of the job name and step name
flags (dict) – Command line argument flags in addition to, or that override, the class FLAGS variable. Keys are flag names (“-flag”), values are values for that flag. For flags that take no value, use None as the value. To turn off (not include in the command line) a flag in the class FLAGS variable, use the DO_NOT_USE_FLAG constant as the value.
archive (bool) – If True, instead of copying the subdirectory and individual files, will tar.gz up the entire subdirectory and copy that back.
monitor_globs (list) – List of valid file globs (i.e. ["*.zip"]) that should be monitored for and copied back to the original job directory when they appear. Note that the interaction of archive and moitor_globs is such that if both are specified, the result will be a subdirectory with the monitored files AND an archive of the entire subdirectory (including any monitored files that remain when this step completes).
full_command (list) – the full command line for this step including the driver path, etc. but without $SCHRODINGER/run. The command will be used “as is” except for replacing some pre-defined tokens with job-specific strings - see the createCommand function. Each item of the list is a word of the command line invocation.
local_files (list) – A list of file paths to copy into the job subdirectory before running the command
input_file (str) – The name of the file containing the input structures/data. It is ignored if there is a parent for this step.
cpu_hostname (str) – The name of the host to run CPU processes on
gpu_hostname (str) – The name of the host to run GPU processes on
umbrella (str) – Whether to run drivers that have GPU subjobs in umbrella mode or not. Should be one of UMBRELLA_ALWAYS (always run in umbrella mode even if the flag is not provided), UMBRELLA_NEVER (never run in umbrella mode even if the flag is provided) or UMBRELLA_PER_FLAG (obey the presence or absence of the -md_umbrella flag for this step). This parameter is only used if both cpu_hostname and gpu_hostname are given - if not, UMBRELLA_ALWAYS is enforced.
splitter (bool) – True if this step splits the workflow into parallel workflows, False if it does not. Note that this keyword is ignored if the SPLITTER class constant is True.
split_index (int) – If this step STARTS a new split workflow, the 1-based index of that workflow. Otherwise, just use 1 to indicate that it is the same workflow as the parent step.
split_tag (str) – An extra tag to add to the step name to distinguish between the same stage in parallel workflows
child_stages (list) – A list of child stages that need steps to be created from them. Each item is a jaguar_multistage_workflow_utils.StageData instance. This list contains one StageData item for each child stage no matter how many steps will be created from that stage due to splitting the workflow. For instance, if a workflow is A-B-C-D, and B is a splitter step that splits the workflow into 3 workflows, child_stages for B should be [C], not [C, C, C].
use_jc (bool) – True if the step should use job control, False if not. The default value of None defaults to the class USES_JC constant.
tpp (int) – The number of threads per process. Serial processes use 1 thread. This will be added to the step command via -TPP tpp.

See parent class for additional documentation

Raises:: ValueError – if umbrella is not an allowed value
