Dimuthu Upeksha commented on AIRAVATA-2717: ------------------------------------------- [~marcuschristie] Yeah I guess that's what we want. Sorry for my misrepresentation. Let's use a higher level workflow to connect applications rather than composing everything in a single workflow. > [GSoC] Resurrect User-Defined Airavata Workflows > ------------------------------------------------- > > Key: AIRAVATA-2717 > URL: https://issues.apache.org/jira/browse/AIRAVATA-2717 > Project: Airavata > Issue Type: Epic > Affects Versions: 0.17 > Reporter: Suresh Marru > Priority: Major > Labels: gsoc2018 > > Airavata used to support user-defined workflows using an interface XBaya to > drag and drop application components to a workspace and define data flow and > control flow dependencies among the application nodes. Airavata's workflow > system was used for composing, executing, and monitoring workflow graphs > primarly web service components. The workflow description was high level > abstraction and used to be converted to lower level execution run times like > BPEL, SCUFL and Python scripts. > > Airavata has evolved significantly and the current development version is > being built-over Apache Helix for DAG orchestration. This provides an > opportunity to resurrect workflow capabilities in Airavata. > This GSoC project involves finalizing a Airavata Workflow Language; modify > the orchestrator to parse user described workflow and translate to equivalent > Helix DAG's; execute and monitor the worklfows; develop a simple UI to > demonstrate the capabilities. > To describe the workflows, you can build on this - > [https://docs.google.com/document/d/1eh7BV8CHupxyM2jeqcM2tUG5MnXFt7hNDX4PQDfxCcM/edit] > or follow other discussions like - > https://issues.apache.org/jira/browse/AIRAVATA-2555 and > User community & Impact of the software: Airavata is primarily targeted to > build science gateways using computational resources from various > disciplines. The initial targeted set of gateways include projects supporting > research and education in chemistry, biophysics, and geosciences . The goal > of airavata is to enhance productivity of these gateways to utilize > cyberinfrastructure of resources (e.g., local lab resources, the Extreme > Science and Engineering Discovery Environment (XSEDE), University Clusters, > Academic and Commercial Computational Clouds. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
