The sungrid job submission framework known as qsub is a powerful tool to distribute your workload over many machines in parallel. To check the status of the jobs in the queue there is qstat which can print a human readable status table on the command line. Such status can be useful to keep track of your submitted compute jobs to e.g. prevent duplicate submission.
This python qstat wrapper parses the jobs listed in qstat -xml into a list of dictionaries.
Install with
.. code::
$ pip install qstatUsage
Get python dictionaries descibing your ```qsub``` jobs.
.. code:: python
from qstat import qstat
queue_info, job_info = qstat()
queue_info[13]
.. code:: python
{'@state': 'running',
'JAT_prio': '0.55008',
'JAT_start_time': '2017-09-04T16:22:50',
'JB_job_number': '6384796',
'JB_name': 'phs_obs_20120102_001',
'JB_owner': 'relleums',
'queue_name': 'test@isdc-cn11.astro.unige.ch',
'slots': '1',
'state': 'r'}
Add both ```queue_info``` and ```job_info``` to have one list of both running and waiting jobs:
.. code:: python
from qstat import qstat
queue_info, job_info = qstat()
all_jobs = queue_info + job_info
for job in all_jobs:
print(job['JB_name'], 'is', job['@state'])
::
my_job_001 is running
my_job_002 is running
my_job_003 is running
or combine with e.g. with pandas DataFrame
.. code:: python
from qstat import qstat
q, j = qstat()
import pandas as pd
df = pd.DataFrame(q + j)
df.tail()
::
