Data Activated 流 Graph Engine
DALiuGE is a workflow graph execution framework, specifically designed to support very large scale processing graphs for the reduction of interferometric radio astronomy data sets. DALiuGE has already been used for processing large astronomical datasets in existing radio astronomy projects. It originated from a prototyping activity as part of the SDP Consortium called Data Flow Management System (DFMS). DFMS aimed to prototype the execution framework of the proposed SDP architecture.

The easiest way to get started is to use the docker container installation procedures provided to build and run the daliuge-runtime and the daliuge-translator. Please refer to the README files in the subdirectories daliuge-runtime and daliuge-translator, respectively. Depending on what you want to deploy you may need to build and run only the runtime or the translator.
It is also possible to install the latest stable version of the full package using PyPi:
pip install daliuge
If you only want the translator engine and don't need the runtime, or vice-versa, you can install them separately:
pip install daliuge-translator pip install daliuge-runtime
Or if you plan to develop DALiuGE:
git clone https://github.com/ICRAR/daliuge cd daliuge pip install -e daliuge-common pip install -e daliuge-translator # optional pip install -e daliuge-runtime # optional
Porting from DALiuGE 0.X
With the release of DALiuGE 1.0.0 the code has been broken down into separate packages to accommodate leaner and easier installations when only a subset of the functionality is required. In doing so we tried to maintain as much backward compatibility as possible, but there are some minor exceptions:
- Code doing
from dlg import delayedor similar must be changed to
from dlg.runtime import delayed.
- Scripts finding the include directory path for daliuge headers using code like
python -c 'import dlg; print(dlg.get_include_dir())should switch to invoke
