摘要
高性能计算机是推动工业发展的重要工具和手段。本文综述高性能计算机发展的几个关键问题,阐明处理器的发展趋势正在过渡到新一代多核心异构并行计算系统过程中,其中多核心缓存设计和多核心异构编程模型设计是关键因素,云计算技术可能成为将来高性能计算的重要推动因素。最后,结合石油勘探中对计算机的需求,以CPU+GPU的异构计算系统为例,阐明高性能计算的重要推动作用。并行算法的开发平台和程序设计方法是影响石油勘探中的高性能计算应用的主要瓶颈;磁盘I/O、高速网络和并行文件系统是制约高性能计算的重要因素。
High performance computer （HPC） is an important tool and means to promote the industrial development. This paper points out several key problems in the development of HPC, and expounds the development trend that the processors are in a transition to a new generation of muhi-core heterogeneous parallel computing system, in which the core cache design and multi- core heterogeneous programming model design are the key factors. The cloud computing technology may be an important factor to prmnote the future HPC. Finally, to meet the needs for computers in petroleum exploration, the important role of HPC is further clarified, with the CPU＋GPU heterogeneous system as the example. It is pointed out that the development platform and programming method of parallel algorithm are the main bottlenecks of HPC application in petroleum exploration. I/0 features of disk, high-speed network and parallel file system are also important factors to affect the HPC application.
