The conflict can be resolved by the parallel compute , but two questions exist at the same time . firstly , the related high rank parallel software is so scarce that the parallel computer can only used by the professional programmer 并行机的出现为复杂结构精细分析提供了硬件基础,但由于高层次并行软件的缺乏使得并行计算机往往只能由专业程序员使用,另外,并行机价格昂贵,不易普及。
The arithmetic architecture of parallel pragram is closely related with the architecture of parallel computer system . presently , there are some popular models such as share - memory model , message passing model and data paralleling model 并行计算采用并行程序实现,并行程序设计的算法结构与并行计算机系统结构紧密相关,当前流行的算法结构有共享存储、消息传递、数据并行等多种模型。
This article details the arrangement relationship of independence , order , deflection order and the waterfall arrangement ways according to path number and running time , with the stress on the " trapezoid " arithmetic of batch process in parallel computer 摘要介绍了含有独立、顺序、有偏序关系的批作业的梳理,以及批作业按作业序列路径数、运行时间长短排序的瀑布式方法,重点讲述了并行机批作业执行时的“梯形”算法。
Ga poses implicit parallelism and is suitable for implementation on large scale parallel computers . dividing the whole population into sub - populations and coarse - grained island model of exchanging information among sub - populations are the most direct parallel method Gas具有天然的并行性,非常适合于在大规模并行计算机上实现,把串行gas中的单一群体分成多个子群体,各子群体之间相互交换信息的粗粒度并行是将gas并行化的最直接方式。
This article introduces the developing history and the current situation of the automatic goal discern , and on the basis of structure of the parallel computer and neural network knowledge , it analyses the hardware and software engineering foundation that realized the real - time goal recognition system 介绍了自动目标识别的发展历史和现状,在并行计算机结构和神经网络知识的基础上,分析了实现实时目标识别系统的硬件和软件技术基础。
