Detailed Description

Simple class to help monitor status of jobs submitted by LSF Backend.

You pass in a `Job` object and job id from a bsub command.
When you call the `ready` method it runs bjobs to see whether or not the job has finished.

Constructor & Destructor Documentation

__init__()

def __init__	(		self,
			job,
			job_id
	)

Pass in the job object and the job id to allow the result to do monitoring and perform
post processing of the job.

Definition at line 1654 of file backends.py.

Member Function Documentation

_update_result_status()

def _update_result_status (   self,   bjobs_output  )

private

Parameters:
    bjobs_output (dict): The JSON output of a previous call to bjobs which we can re-use to find the
        status of this job. Obviously you should only be passing a JSON dict that contains the 'stat' and
        'id' information, otherwise it is useless.

Definition at line 1676 of file backends.py.

get_exit_code_from_file()

def get_exit_code_from_file (   self )

inherited

Read the exit code file to discover the exit status of the job command. Useful falback if the job is no longer
known to the job database (batch system purged it for example). Since some backends may take time to download
the output files of the job back to the working directory we use a time limit on how long to wait.

Definition at line 879 of file backends.py.

ready()

def ready (   self )

inherited

Returns whether or not this job result is known to be ready. Doesn't actually change the job status. Just changes
the 'readiness' based on the known job status.

Definition at line 858 of file backends.py.

update_status()

def update_status

(

self

)

Update the job's (or subjobs') status by calling bjobs.

Reimplemented from Result.

Definition at line 1663 of file backends.py.

Member Data Documentation

_is_ready

_is_ready

privateinherited

Quicker way to know if it's ready once it has already been found.

Saves a lot of calls to batch system commands.

backend_code_to_status

dictionary backend_code_to_status

static

Initial value:

=  {"RUN": "running",
                                  "DONE": "completed",
                                  "FINISHED": "completed",
                                  "EXIT": "failed",
                                  "PEND": "submitted"
                                  }

LSF statuses mapped to Job statuses.
