EUFORIA (EU Fusion for Iter Applications) is a project of the European Union in the Seventh Framework Program ( FP7 ), which sets up and provides a framework and infrastructure for transport and turbulence simulations for fusion research with grid and high-performance computing .

The EUFORIA project will improve the modeling capabilities of ITER Plasma by adapting, improving and integrating a collection of important applications for transport and turbulence simulations in order to combine required computing paradigms (serial and parallel grid computing and high-performance computing ). The development of a grid service and high-performance computer services form the basis of the project. A new aspect is the dynamic connection and integration of applications, which are available in a collection of heterogeneous platforms, in a simple common framework with a workflow engine. In order to improve modeling capabilities of fusion - plasma while supporting new computer infrastructure and tools for fusion -Gesellschaft.

The concept of the EUFORIA project

implementation

The "first phase" of the EUFORIA project is a development phase to adapt and improve certain applications of transport and turbulence simulations for grid and high-performance computer environments. This includes providing the computer infrastructure and resources for the project consortium .

Therefore this phase is mainly aimed at the code and application developers with the focus on the detailed implementation of the physical code. General tutorials on the various aspects of application customization will be made available to the consortium and other fusion scientists. The experiences made during the development work of the fusion code will be published and direct user support for new users who want to bring their applications into the EUFORIA platform will be offered. This activity alone will provide a significant step forward in terms of the modeling capacities and capabilities of the fusion- modeling society.

The “second phase” is a standardization and integration phase. In a technology-driven part, the technologies and tools are developed in order to offer users transparent methods for resource allocation and planning as well as a dynamic coupling of the physics and the user and physics code components. The technology for creating complex workflows with the improved codes, the components, the standardized data structures and the transfer methods are used to expand the physical areas of ITER development. Important steps here are the adaptation of a uniform project-wide data structure and the adaptation of a workflow orchestration tool and general tools for examining and visualizing the data.

aims

The EUFORIA project aims to achieve the following results:

In addition, there are a number of activities to disseminate the project results.

As you can see in the list above, the project consists of a collection of work packages. A high degree of coordination and monitoring is required in the management structures of the project in order to guarantee the timely creation of the individual components.

Project structure

The EUFORIA project is structured in networks , services and research :

Networks

  • NA1 management
  • NA2 - user documentation and training
  • NA3 - dissemination

Services - Publications and Workflows

Research activities

  • JRA1 - Adaptation of the codes and tools in the grid infrastructure
  • JRA2 - Adaptation of the codes and tools in the high-performance computer infrastructure
  • JRA3 - Physics Integration - Workflow Orchestration Tools
  • JRA4 - visualization

Network Activities (NA)

Activity NA1: Management

NA1 provides administrative support and management for the consortium. In addition to coordinating the various activities, NA1 is responsible for securing and promoting communication between the research and service activities to ensure the integration of the results. The connections to other international projects and initiatives, both in grid and high-performance computing , as well as in the fusion community are being determined. Management will liaise with the code owners and users of the merger company to publish additional computer resources for research in physics through the EUFORIA code. It is also determined whether additional funding from the EU and the consortium can be acquired.

As the various sub-areas become more and more integrated over time, more attention is required in the area of joint research and in the collaboration between research and service . In addition, efficient coordination is a prerequisite for achieving the planned goals. Another goal is for those who have been trained to pass on their knowledge of the EUFORIA project independently.

A merger-based coordination team will deploy good technology support within the leadership group to harmonize infrastructure development and the modeling requirements required by ITER and to maintain contact with physics development and modeling activities within ITER -Partners.
