Chemomentum - Grid Services Based Environment to Enable Innovative Research
This contribution will present current status of the UNICORE with the focus on its grid services implementation. The ongoing development to create grid based, workflow centric chemistry workbench will also be presented.
The recent version of the UNICORE is a Grid Service infrastructure compliant with the Open Grid Services Architecture (OGSA). It is based on the UNICORE Grid software which becomes important toot to access HPC systems in European HPC Centers. UNICORE is already an integrated Grid solution supporting challenging scientific and industrial applications and complex work flows in production environments that span multiple independent organisations. One of the important enhancements developed within UNIGRIDS project are generic software components for visualization and steering of simulations, remote device monitoring and control will be developed to broaden the applicability of Grid computing to new scientific and technological areas. UNICORE/GS allows also for seamless access to the distributed data and databases.
The Chemomentum is newly establish EU project coordinated by ICM (IST Call 5) which will provide Grid-based solutions for workflow-centric, complex applications, such as risk assessment, toxicity prediction and drug design, It focuses on tools for dealing with data and knowledge in an efficient and reliable manner. The Chemomentum software will enable users to assess the knowledge stored in the system in terms of applicability, range of validity and reliability, and will make it easy to use this knowledge for predictive and decision-making purposes. Leveraging developments in enterprise software systems, such as service oriented architectures and business integration, Chemomentum will achieve these aims by taking up and enhancing European Grid middleware. Grid-enabling relevant applications and building services on the Grid, Chemomentum will provide 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 will allow the users to focus on their work, keeping any Grid related complexity hidden. Administration of the Grid, for example management of users, software license management and application deployment on the Grid will be greatly simplified.
D-Grid, or How to Build a National Grid Infrastructure
Globalization demands global infrastructures, e.g. for transportation, communication, and collaboration. The latter, collaboration, will be facilitated by grid infrastructures, which are currently being built in hundreds of grid projects around the world.
One of them, the 5-year German D-Grid initiative, aims at developing a common grid infrastructure to provide "Services for Scientists". The grid infrastructure will be tested by six Community Grids (high-energy physics, astronomy, climate, medicine, engineering, libraries).
Recently, a 2nd Call invited new communities, IT service providers and industry users to help expand the user community, and to strengthen D-Grid towards a productive and sustainable service platform for science and industry.
This lecture will present an overview on D-Grid, and its challenges and benefits for the national and international science and industry community. We will offer "Lessons Learned" and "Recommendations" to those who intend to build similar grids in the near future.
Grid Security - Principles and Practices
Grid security remains an issue for the researchers and developers to better address. Security issues were virtually overlooked in the evolution of grid technology; however, these issues are now coming to the fore with the growing size and profile of the grid community. This tutorial is designed to address the growing need of disseminating security knowledge to the grid community. It will also give an insight to the privacy and trust issues. The attendees of this tutorial will learn core security technologies and their holistic implementation in the grid environments.
The tutorial is organised in three parts: security concepts, security implementations, and grid security practices.
There is no specific prerequisite for the participants as the relevant concepts will be elaborated before the exercises; however, prior knowledge of algebra, object oriented programming, experience of using some grid middleware, or familiarity with security tools (such as openssl) will help the attendees to quickly advance the exercises.

Performance Evaluation of Gigabit Ethernet-Based Interconnects for HPC Clusters
Paper presents performance evaluation results of widely used MPI communication protocol based on Gigabit Ethernet interconnect and TCP/IP protocol stack. New message propagation model is proposed and corresponding experimental results are presented. Performed research proved existence of several bottlenecks resulting in significant communication overhead. Proposed new stack and driver implementation will significantly reduce the message propagation latency in the comparison to standard TCP/IP implementation. Presented results will be used in development of new product which is the Gigabit Ethernet-based RDMA stack for GNU/Linux operating system.
