Welcome to the Data Activated 流 1 Graph Engine (DALiuGE).

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. For a complete tour of DALiuGE please read our overview paper. DALiuGE has been used in a project running a full-scale simulation of the Square Kilometre Array dataflow on the ORNL Summit supercomputer.


Development and maintenance of DALiuGE is currently hosted at ICRAR and is performed by the DIA team.
