Acquisition of Beowulf Cluster for a Center for Computational Astrophysics at the University of California, Santa Cruz

AST-0521566/Woosley，UCSC该项目将提供必要的超级计算资源，以研究加州大学圣克鲁斯（UCSC）天体物理学、行星科学和望远镜仪器设计中的大约12个重大挑战问题。主要用户将包括大约25名研究生和博士后。建议的设备是一个280节点的Beowulf Linux集群，每个节点有两个AMD 246 64位处理器。每个节点也将有4 GB的内存，整个机器将由20 TB的磁盘存储在一个快速RAID系统。该系统将部署各种高度并行化、可生产的代码，以模拟宇宙学、结构形成、超新星、伽马射线爆发、磁流体力学、行星形成和结构、微行星碰撞和自适应光学。

AST-0521566/Woosley, UCSCThis project will provide the necessary supercomputing resources to study roughly a dozen grand-challenge problems in astrophysics, planetary science, and telescope instrument design at the University of California, Santa Cruz (UCSC). Principal users would include approximately 25 graduate students and postdocs. The equipment proposed is a 280-node Beowulf Linux cluster having two AMD 246 64 bit processors per node. Each node will also have 4 Gbytes of memory and the overall machine will be served by 20 TB of disk storage in a fast RAID system. A variety of highly parallelized, production-ready codes will be fielded on this system to simulate cosmology, structure formation, supernovae, gamma-ray bursts, magnetohydrodynamics, planetary formation and structure, planetesimal collisions, and adaptive optics.
