UNICORE (Uniform Interface to Computing Resources) offers a ready-to-run Job submission system including client and server software. UNICORE makes distributed computing and data resources available in a seamless and secure way in intranets and the internet (https://www.unicore.eu/).
UCC (Unicore Command Line Client)
The UNICORE Commandline Client (UCC) is a full-featured client for accessing UNICORE services. It requires a Java runtime environment, version 11 or later. We recommend using the OpenJDK.
UCC offers:
- Job submission and management
- Data movement (upload, download, server-to-server copy, etc) using the UNICORE storage management functions and the available data transfer protocols
- Storage functions (ls, mkdir, ...) including creation of storage instances via storage factories
- UNICORE Workflow service support and much more.
