7. Unicore and JSDL Job Submission Description Language Capabilities
Pre-stage, Execute, Post-stage.
Uniformity across batch subsystems.
Support for multiple file transfer protocols.
Capabilities
Optional data sources/sinks, with different credentials possible
Seamless or restricted resource description
Abstract or concrete application description
Suitable for Unicore resource broker and NAREGI scheduler
Act as JSDL to JSDL processors
Restrictions
No support for “Multi-Jobs” or work-flow.
Prototype Working in Production
