  • Overview gives an overview of the UNICORE features and the UNICORE architecture.

User Documentation

  • UCC - a full featured commandline client for UNICORE.

  • REST API - REST-API for job submission and management, data access and transfer, workflow submission and management

Administrator Documentation

  • Gateway - an optional server component that provides a reverse https proxy, allowing you to run several backend servers (UNICORE/X, Registery, …) behind a single address.

  • UNICORE/X - the central server component of a typical UNICORE installation that provides REST APIs for job management and data access services for a single compute cluster (or just a file system).

  • TSI - the Target System Interface (TSI) server is used to interface to a resource manager such as Slurm and to access files on the cluster.

  • XUUDB - an optional service, that is best suited as a per-site service, providing attributes for multiple UNICORE/X-like services at a site. The XUUDB maps a UNICORE user identity (which is formally an X.500 distinguished name (DN)) to a set of attributes which are typically used to provide local account details (uid, gid(s)) and commonly also to provide authorization information, i.e. the user’s role.

  • Workflow service - provides advanced workflow processing capabilities using UNICORE resources. The Workflow service provides graphs of activities including high-level control constructs (for-each, while, if-then-else, etc), and submits and manages the execution of single UNICORE jobs.

  • Registry - the Registry server is a specially configured UNICORE/X server which provides the information about available services to clients and other services.

  • UFTPD - the UNICORE File Transfer Server for high performance data transfer
