Overview

UNICORE (UNiform Interface to COmputing REsources) is part of the European Middleware
Initiative's middleware distribution. Several UNICORE Clients exist to access resources managed by UNICORE services.
This presentation is a tutorial for users of the EGI infrastructure who are using or want to use such resources.
It will cover the command line (UCC) and the Eclipse-based rich client (URC) in presentation and hands-on practical.

Description of the work

Services of the UNICORE grid middleware are part of the EMI Distribution.
UNICORE comes with a history of more than 10 years. Originally initiated
in the Supercomputing domain, today UNICORE is a general-purpose Grid technology.
In its recent version, UNICORE 6 follows the latest standards from the Grid and
Web Services world and offers a rich set of features to its users.

UNICORE is used in Grid infrastructures of different nature and without
limitations on the type of computing resources such as NGI-PL, NGI-DE or DEISA.
Being Java-based UNICORE is portable. In order to achieve interoperability it
uses HTTPS-based Web services as well as several common open Grid standards.
UNICORE provides users with a strong security based on a rule-based access control engine (SAML).

UNICORE provides an easy-to-use Grid system that focuses on the end users,
allowing them to use powerful tools in an efficient and transparent way.
Intuitive, task-oriented user interfaces allow the users to focus on their work,
keeping the Grid related complexity hidden.

The UNICORE tutorial is dedicated to the Grid users and will allow for practical
examination of the UNICORE tools. The tutorial will briefly cover prerequisites to
using the clients such as the installation and the general process of the obtaining
an X509 certificate necessary to access Grid resources. Users will get familiar
with the different clients, especially the UNICORE Command line Client (UCC) and
the Eclipse-based UNICORE Rich Client (URC). The users will be instructed how to
prepare a job description including the related data management instructions, submit
it to the grid and monitor its execution. The results retrieval will be presented
as well. A part of the tutorial will be dedicated to workflow creation and its
execution on the grid infrastructure. The tutorial will also cover the integration
of user application in the client and UNICORE core services.

Impact

This tutorial will enable users of the EGI infrastructure to exploit data and compute
resources available through UNICORE and other services offering the OGSA-BES
(Open Grid Services Architecture - Basic Execution Service) interface.
