UNICORE: Job Submission

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 8 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.
