MRI: Acquisition of Computationally Intensive Research in High Energy Physics

高能物理与高性能科学计算有着长期而密切的联系。实验HEP的大型粒子探测器采集的数据样本需要大量的数据处理和处理负荷。对于即将在瑞士日内瓦的欧洲核子研究中心上线的大型强子对撞机实验来说，巨大的计算需求极大地推动了网格计算的发展。即使是传统上不需要大量计算资源的实验类别，如中微子实验，现在也产生了大量的统计数据集，这些数据集需要大量的计算资源来分析和解释最近的实验结果。在理论方面，强相互作用（QCD）的物理学在分析上难以解决当前广泛关注的问题。晶格QCD是一个工具，它允许我们研究QCD的动力学，理解某些低能量现象是如何产生的，并计算标准模型的结果。它有望在支持实验工作和发现新物理学方面发挥重要作用。对高精度、现象上有趣的点阵量子cd计算的计算需求是如此之高，以至于需要高性能的大规模并行超级计算机。然而，小规模的资源对于发展新思想和培养研究生和本科生也是至关重要的。此外，具有足够本地存储的小规模资源可以在大型机器上产生的规范场组态和夸克传播子的分析中发挥重要作用。这部分分析通常由大学里的小组来完成。该提案解决了wamp；M中微子群和更大的中微子群体在MINOS中微子探测器中模拟中微子相互作用的计算需求，这些探测器目前在伊利诺伊州巴达维亚的费米实验室和明尼苏达州北部的苏丹地下实验室运行。同时，该提案将提供一个设施，用于在lattice QCD中执行小型试点项目，并支持在主要lattice QCD机器上执行的大型计算的数据分析要求。实际上，该提案使pi和W&amp；M学生能够在更大的Lattice QCD社区中发挥重要作用，并允许他们访问该领域的主要计算结果。

High energy physics has a long and close association with high performance scientific computation. The data samples collected with massive particle detectors of experimental HEP require significant data handling and processing loads. The push for grid-based computing was significantly driven by the phenomenal computing needs expected for the LHC experiments that will soon be coming online at CERN in Geneva, Switzerland. Even categories of experiments that traditionally do not demand large computation resources, such as neutrino experiments, are now producing high statistics datasets that are requiring significant computational resources for analysis and interpretation of the results of recent experiments.On the theoretical side, the physics of the strong interaction (QCD) had been analytically intractable for a wide range of problems of current interest. Lattice QCD is a tool that allows us to investigate the dynamics of QCD, understand how certain low energy phenomena arise, and compute the consequences of the Standard Model. It is expected to play an important role in supporting the experimental effort and in discovering new physics. The computational demands for the high precision, phenomenologically interesting lattice QCD calculations are such that high performance massively parallel supercomputers are required. However, small scale resources are also critical for developing new ideas and training graduate and undergraduate students. In addition, small scale resources with enough local storage can play an important role in the analysis of the gauge field configurations and quark propagators generated on the big machines. This part of the analysis is usually done by small groups located at universities.This proposal addresses the computational needs of the W&M neutrino group and the larger neutrino community for simulations of neutrino interactions in the MINOS neutrino detectors currently operation at Fermilab in Batavia, Illinois and the Soudan Underground Lab in northern Minnesota. Concurrently, this proposal will provide a facility for performing small pilot projects in lattice QCD and for supporting the data analysis requirements of the large computations performed on the major Lattice QCD machines. In effect, this proposal enables the PIs and W&M students to play a significant role in the larger Lattice QCD community and allow them access to the results of the major computations in this area.
