Workflow

Simple workflow

A simple workflow is implemented with the function mainflow defined in views.py and a template defined in `templates/job_template.j2`:

+-- views.py
+-+ templates/
  + job_template.j2

views.py:

from jobbergate import appform

def mainflow(data):
    return [appform.Text("jobname", "What is the jobname?", default="simulation")]

job_template.j2:

#!/bin/bash
#SBATCH -j {{ data.jobname }}
sleep 30

Workflow with implicit workflows

A workflow with implicit workflows is built by defining mainflow and functions decorated with `appform.workflow`:

+-- views.py
+-+ templates/
  + job_template.j2

views.py:

from jobbergate import appform

def mainflow(data):
    return [appform.Text("jobname", "What is the jobname?", default="simulation")]

@appform.workflow
def debug(data):
    return [appform.Confirm("debug", "Add debug info?")]

@appform.workflow
def gpu(data):
    return [appform.Integer("gpus", "Number of gpus?", default=1, maxval=10)]

job_template.j2:

#!/bin/bash
#SBATCH -j {{ data.jobname }}


{% if data.gpus %}
NUMBER_OF_GPUS={{ data.gpus }}
{% else %}
NUMBER_OF_GPUS=0
{% endif %}

{% if data.debug %}
/application/debug_prepare
{% endif %}

/application/run_application -gpus $NUMBER_OF_GPUS
