Radio Synthesis Imaging: An HPCC Application

大挑战应用组竞赛为科学家和工程师组成的多学科团队提供了一种支持机制，以实现1992财年高性能计算和通信(HPCC)倡议的目标。理想的建议不仅提供了卓越的科学领域：集中的问题，可能在科学和工程的关键领域产生重大影响，而且还提供了科学活动和比较活动之间的重大互动，通常涉及数学、计算机或计算科学家，这些活动将对特定科学或工程问题领域或正在研究的学科以外的高性能计算活动产生影响(S)。这项建议是为了直接实施天文学和天体物理学调查委员会的三项计算建议。它将实施下一代天文望远镜系统的原型-通过高速网络连接到非常高性能、可扩展体系结构的计算机和在线数据档案的远程望远镜。将优化计算非常密集的射电综合阵列观测定标和成像算法，并将开发利用大规模并行CM-5的新算法。

The Grand Challenge Application Groups competition provides one mechanism for the support of multidisciplinary teams of scientists and engineers to meet the goals of the High Performance Computing and Communications (HPCC) Initiative in Fiscal Year 1992. The ideal proposal provided not only excellence in science: focussed problem with potential for substantial impact in a critical area of science and engineering but also significant interactions between scientific and comptational activities, usually involving mathematical, computer or computational scientists, that would have impact in high-performance computational activity beyond the specific scientific or engineering problem area(s) or discipline being studied. This proposal is for the direct implementation of three computing recommendations of the Astronomy and Astrophyusics Survey Committee. It will implement a prototype of the next generation of astronomical telescope systems - remotely located telescopes connected by high speed networks to very high performance, scalable architecture computers and on-line data archives. The very computationally intensive algorithms for calibration and imaging of radio syntheseis array observations will be optimized and new algorithms which utilize the massively parallel CM-5 will be developed.
