ESRF Workflow System

Ewoks: ESRF Workflow System

Many workflow management systems exist to deal with data processing problems that can be expressed as a graph of tasks, also referred to as a computational graph or workflow. The main purpose of a workflow management system is to provide a framework for implementing tasks, creating graphs of tasks and executing these graphs.

The purpose of ewoks is to provide an abstraction layer between graph representation and execution. This allows using the same tasks and graphs in different workflow management systems. ewoks itself is not a workflow management system.

Install

python3 -m pip install ewoks[orange,dask,ppf,test]

Test

python3 -m pytest --pyargs ewoks.tests

Getting started

Workflows can be executed from the command line

ewoks execute /path/to/graph.json [--binding dask]

or for an installation with the system python

python3 -m ewoks execute /path/to/graph.json [--binding dask]

Workflows can also be executed from python

from ewoks import execute_graph

result = execute_graph("/path/to/graph.json", binding="dask")

When no binding is specified it will use sequential execution from ewokscore.
