项目摘要

The primary focus of fusion energy research over the past decades hasbeen on magnetic confinement devices called tokamaks. The UK's JETfacility is currently the largest tokamak in the world but will be surpassedby the international ITER device, now under construction in France.Providing computational resources in support of ITER is a dedicated HighPerformance Computer for Fusion (HPC-FF) at Jülich, Germany, which willsoon be expanded at Rokkasho, Japan in the International Fusion EnergyResearch Center within the ``broader approach" framework betweenJapan and the EU. Operation is planned to start in 2012. Simulation isrequired in three principal areas: plasma physics, the powerful controllingplasma-solid interaction/interface, and materials science. We haveconstructed a consortium involving six countries (France, Germany, Japan,Russia, UK and USA) with expertise in all three of these applicationsdomains as well as the underpinning computational science techniques.We propose to use these skills to undertake an integrated researchprogramme focussed on investigating the scaling of key codes which haverelevance for providing experimentally validated predictive capabilities formagnetic fusion systems.On the path towards an economical magnetic confinement fusion reactorintegrated numerical models can speed up technological but also physicalprogress, even mitigating possible bottlenecks.Our proposal concentrates on codes for three scientific areas, the plasmaitself, the materials from which a reactor will be built, and the physics of theplasma edge.Previous research on materials and plasmas has been conductedindependently, and a key aspect of the proposal is to ensure that scientistsworking in these areas are well versed in all the issues affecting putativedevices. We will train a cohort of young scientists who are genuinelyexpert in "Fusion Energy", as opposed to the current division of expertisebetween plasma physicists, reactor engineers and materials scientists.This group will comprise both the researchers paid for by the project, andthe students funded by the constituent universities to work alongside them.It will also bring together the international group of senior scientists (PIs)from different fields united in the goal of supporting a practical fusionenergy device. The collaborative training courses will ensure thatexpertise in one area is matched by an understanding of the other.Particularly in materials science, researchers are using codes developedto treat a wide range of materials. The issues relevant for fusion are morespecific, and there is plenty ofscope for both algorithmic and parallelisation developments to lead tosignificant speed-ups.By concentrating on community codes, we will ensure that the exascaledevelopments of the project are of benefit to a wide range of externalusers, in addition to the scientists working on the project itself.

过去几十年来，聚变能研究的主要焦点是称为托卡马克的磁约束装置。英国的 JET 设施是目前世界上最大的托卡马克装置，但将被法国正在建设的国际 ITER 装置超越。提供计算资源。支持 ITER 的是位于德国于利希的专用高性能聚变计算机 (HPC-FF)，该计算机很快将在国际聚变中扩展到日本六所村日本和欧盟之间“更广泛的方法”框架内的能源研究中心计划于 2012 年开始运营。三个主要领域需要进行模拟：等离子体物理、强大的控制等离子体-固体相互作用/界面以及材料科学。已经建立了一个由六个国家（法国、德国、日本、俄罗斯、英国和美国）组成的联盟，该联盟拥有涉及其中三个应用领域以及基础计算科学技术的专业知识。我们建议使用这些进行综合研究计划的技能，重点是研究关键代码的扩展，这些代码与为磁聚变系统提供经实验验证的预测能力相关。在走向经济的磁约束聚变反应堆的道路上，集成数值模型可以加速技术进步，也可以加速物理进步，甚至减轻可能的瓶颈。我们的提案集中于三个科学领域的代码：等离子体本身、建造反应堆的材料以及等离子体边缘的物理原理。材料和等离子体的研究是独立进行的，该提案的一个关键方面是确保在这些领域工作的科学家精通影响假定设备的所有问题，我们将培训一批真正的“聚变能源”专家的年轻科学家。反对目前等离子体物理学家、反应堆工程师和材料科学家之间的专业划分。该小组将包括该项目资助的研究人员以及由组成大学资助的与他们一起工作的学生。它还将汇集国际小组来自不同领域的资深科学家 (PI) 联合起来，共同支持实用的聚变能源装置。协作培训课程将确保一个领域的专业知识与另一个领域的理解相匹配。特别是在材料科学领域，研究人员正在使用开发的代码来实现。处理广泛的材料。与融合相关的问题更加具体，算法和并行化的发展都有很大的空间来显着加速。通过专注于社区代码，我们将确保百亿亿次的发展。该项目除了从事该项目本身的科学家之外，还对广泛的外部用户有益。
