UNICORE: A Grid Computing Environment for Distributed and Parallel Computing

UNICORE (UNiform Interface to COmputer REsources) provides a seamless and secure access to distributed supercomputer resources. This paper will give an overview of the its architecture, security features, user functions, and mechanisms for the integration of existing applications into UNICORE. Car-Parrinello Molecular Dynamics (CPMD) application is used as an example to demonstrate the capabilities of UNICORE.

The UNICORE Rich Client: Facilitating the Automated Execution of Scientific Workflows

Today, many scientific disciplines heavily rely on computer systems for in-silico experimentation or data management and analysis. The employed computer hard- and software is heterogeneous and complies to different standards, interfaces and protocols for interoperation. Grid middleware systems like UNICORE 6 try to hide some of the complexity of the underlying systems by offering high-level, uniform interfaces for executing computational jobs or storing, moving, and searching through data. Via UNICORE 6 computer resources can be accessed securely with different software clients, e.g. the UNICORE Command line Client (UCC) or the graphical UNICORE Rich Client (URC) which is based on Eclipse. In this paper, we describe the design and features of the URC, and highlight its role as a flexible and extensible Grid client framework using the QSAR field as an example.

High-Performance Computer Management Based on JAVA

Coupling of distributed computer resources connected by a high speed network to one virtual computer is the basic idea of a metacomputer. Access to the metacomputer should be provided by an intuitive graphical user interface (GUI), ideally WWW based. This paper presents a metacomputer architecture using a Java based GUI. The concept will be discussed with regard to security, communication, scalability, and the integration into existing frameworks.

Uniform access to the distributed resources for the computational chemistry using UNICORE

In this paper we describe deployment of qunatum chemical and biomolecular applications on the grid. We have used UNICORE infrastructure as framework for development dedicated user interface to the number of existing computational chemistry codes as well as molecular bilogy databases. The user interface is integrated with the UNICORE client based on plugin mechanism which provides general grid functionality such as single login, job submission and control mechanism.

High-performance computer management based on Java

Abstract Coupling of distributed computer resources connected by a high speed network to one virtual computer is the basic idea of a metacomputer. Access to the metacomputer should be provided by an intuitive graphical user interface (GUI), ideally world wide web (WWW) based. This paper presents a metacomputer architecture using a Java based GUI. The concept will be discussed with regard to security, communication, scalability, and the integration into existing frameworks.

In-vessel calibration of the imaging diagnostics for the real-time protection of the JET ITER-like wall

The in situ absolute calibration of the JET real-time protection imaging system has been performed for the first time by means of radiometric light source placed inside the JET vessel and operated by remote handling. High accuracy of the calibration is confirmed by cross-validation of the near infrared (NIR) cameras against each other, with thermal IR cameras, and with the beryllium evaporator, which lead to successful protection of the JET first wall during the last campaign. The operation temperature ranges of NIR protection cameras for the materials used on JET are Be 650-1600 °C, W coating 600-1320 °C, and W 650-1500 °C.
