 Simplified Unicore 6 architecture The UNICORE system consists of several components which interact over the network
- A provider site.
- Resources sites.
- The user uses the UNICORE client to access the resources.
- All connections need to pass the Gateway, which authenticates the user and routes the connections to one of the UNICORE/X or other services.
- The XNJS uses the Incarnation Database (IDB) to map jobs on the local system.
- When the user is authorized as described in the UNICORE User Database (XUUDB), the UNICORE/X forwards the job to the Target System Interface (TSI).
- The TSI in turn uses the local resource management system of the resource, a Local Resource Management System (LRMS), usually batch system, to submit the job to Worker Nodes (WNs).
UNICORE/X is a container for the UNICORE 6 atomic services (UAS) comprising a TargetSystemFactory (TSF), TargetSystemServices (TSS), StorageManagementServices (SMS), JobManagementServices (JMS) and FileTransferServices (FTS). It also includes a Registry service for finding available service instances. In addition, you can use it as a basis for developing your own WSRF-based services if you wish to extend UNICORE.
It supports the following specifications.
- WS-Resource, WS-ResourceProperties, WS-ResourceLifetime
- Service Group
- WS-BaseNotification
- JSDL 1.0
The XNJS is the component that deals with the actual job execution and file access. It is configured using XML files.
