1、浅谈超级计算机,033351 刘晓祎 033356 罗 为 033308 胡 聪 指导教师: 张晨曦 刘依,超级计算机论文结构,理念,产生,优点,缺点,应用,发展,庞大数据库的产生,精确计算的要求,运行速度极快 海量存储,造价高 用户界面不方便 工程设计困难,应用特点(1.机群系统主流2.商用标准互联3.工业,科研学术) 应用领域(气象预报,整治环境,医学,地震预报,虚拟现实,动画制作),1.高性能计算机群 2.性能提升猛,更新速度快 3.IBM,intel处理器,能够进行大规模、超速运算的计算机,史诗篇-,60多万幅画面 350多TB 的磁盘存储空间 63万张CD光盘 50英里长的胶卷,(注
2、：1TB=1024GB),相当于,超级计算机,Ranks number 1 in the worldinstalled at the Department of energys/National Nuclear Security Administrations Lawrence Livermore National Laboratory (LLNL). 64 rack, 130,000 PowerPC allow dense packaging of processors, memory and interconnect,Blue Genes Goal,Applicable to import
3、ant workloads,Develop a massively parallel computer applied to the study of bio-molecular phenomena Ranks at climates, sub-nuclear physics,Innovative design for ultrascalable computing,Blue Gene is built up as follows: two nodes per compute card, 16 compute cards per node board, 16 node boards per 5
4、12-node mid-plane and two mid-planes in a 1024-node rack. Each processor can perform four floating point operations per cycle. Depending on the nature of the application to be run on Blue Gene, the programmer may choose to employ both processors in a compute node for computation or have one processo
5、r dedicated to handling message passing operations.,In addition to the compute nodes, the system provides for a flexible number of dual-processor I/O nodes which handle communication between compute nodes and other systems.,单元结构和传统体系结构的差别,基于简化的处理器设计构成的多内核芯片系统较传统复杂微处理器设计在处理大量并行应用方面效率更高 高带宽低延迟的嵌入式DRAM 通信资源和内存资源的利用率高 节点上操作系统的内核简单 同时多线程技术（Simultaneous multithreading）,QA,033351 刘晓祎 033356 罗 为 033308 胡 聪,Thank you!,
