1 Overview

1.1 Introduction

One method of creating, submitting and monitoring your DEISA production jobs is via the UNICORE Rich Client (URC), without the need for the user to know the details of the target platform’s batch system. Indeed, UNICORE provides a seamless, uniform and secure access to the heterogeneous DEISA infrastructure. This document briefly describes the installation, configuration, and usage of the URC. Links for extended documentation are available in section 1.3.

This document describes the UNICORE installation on a German 32-bit Windows 7 system, thus the screenshots may differ from what appears on other platforms and the window language will be accordant to the default settings of your system.

1.2 Prerequisites

The URC is available on every super computer (target system) within DEISA. Once the URC client is installed on your computer, jobs can be submitted to each of your Execution Sites. The URC is written in Java and is therefore platform independent. The only installation prerequisite is an SUN Java Runtime environment version 1.5 or higher on your workstation. Please be aware that a 32-bit Java version must be installed on a 32-bit system, and a 64-bit Java version must be installed on a 64-bit system.

URC uses Certificates for both authentication and authorization. With this Certificate, the execution sites can be accessed without having to type the password again and again. This is called single-sign-on.

Your URC submits jobs by communicating to UNICORE servers, which reside at each of the DEISA Execution Systems. Just as each user has a personal Certificate, each UNICORE server also has an individual Certificate. If the user trusts the signing Certification Authority (CA) of the server Certificates in the URC, then the client-server connection will be established. DEISA trusts all Certificates that are signed by the EUGridPMA.

For further information on the use of Certificates within DEISA in general, please see the DEISA FAQ at http://www.deisa.eu/usersupport/user-documentation/faq/CertificatesFAQ.
