at a glance

• UNICORE is a fully integrated grid middleware solution which allows creating, submitting and monitoring of computing jobs.

• It mainly consists of a Gateway, a Network Job Supervisor (NJS), a UNICORE User Database (UUDB), an Incarnation Database (IDB), and a Target System Interface (TSI).

Design PrinciplesDesign Principles

• Open source under BSD license with software hosted on SourceForge• Standards-based: OGSA-conform, WS-RF 1.2 compliant• Open, extensible Service-Oriented Architecture (SOA)• Interoperable with other Grid technologies• Seamless, secure and intuitive following a vertical end-to-end approach• Mature Security: X.509, proxy and VO support• Workflow support tightly integrated while being extensible for different workflow

languages and engines for domain-specific usage• Application integration mechanisms on the client, services and resource level• Variety of clients: graphical, command-line, API, portal, etc.• Quick and simple installation and configuration• Support for many operating systems (Windows, MacOS, Linux, UNIX) and batch

systems (LoadLeveler, Torque, SLURM, LSF, OpenCCS)• Implemented in Java to achieve platform-independence

and IPv6

• UNICORE 6 is implemented in Java and concerning IP connectivity issues relies on IPv6 support in Java and libraries

• The program code itself does not deal with IP addresses directly. • Those will be retrieved by name resolution only.• Since IPv6 support generally available in Java, there should be minor

modifications be needed only.• Some 3rd party libraries had issues a long time ago

• No positive or negative confirmation• Might be solved by now• But needs verification in an IPv6 testbed

• Same applies to UNICORE code itself• Hasn’t been tested in IPv6 environment yet• Testers with an access to IPv6 testbed are welcome

IPv6 readiness summary

Until today no requests for IPv6 compliant UNICORE software has been addressed.

Only small modifications will be necessary.

Therefore we assume, that UNICORE 6 will be IPv6 ready as soon as requirement for this will come up.
