Today , multiprocessor systems are cheap and plentiful , nearly every major microprocessor has built - in support for multiprocessing , and many support dozens or hundreds of processors 现在,多处理器系统很便宜,而且数量很多,几乎每个主要微处理器都内置了多处理支持,其中许多系统支持数十个或数百个处理器。
In the implementation , we used the multiprocessing method in qnx to analyze the general flow chart of system , and divided the realization of dual downstream channel into three modules 在具体实现上采用了qnx的多进程编程思想,对整个系统的流程进行了分析设计,将双下行信道的实现分为三个大的模块进行讨论。
In the 2nd and 3rd year , we will keep on developing static / dynamic scheduling techniques for hierarchical systems and design multiprocessing supporting mechanisms such as data prefetch and synchronization primitives 在往后二年中,我们将持续进行静态/动态排程之研究,并设计如同步、资料预先撷取等多处理支援机构。
The other is by means of splitting or partitioning the workload into multiple logical partitions and running the database against multiple logical nodes on a symmetric multiprocessing machine 另一种方法就是通过将工作负载分割或划分成多个逻辑分区,然后在对称多处理机( smp )机器的多个逻辑节点( mln )上运行该数据库。
" department of computer science , princeton university , september 1997 was one of the first papers to explore the potential for a java platform architecture integrating multiprocessing , mobile code , and security ” ( department of computer science ,普林斯顿大学, 1997年9月)是探讨集成多进程、移动代码和安全性的java平台的第一篇论文。
While this support , of course , includes the ability for multiple processors to share peripherals and main memory , it also generally includes enhancements to the instruction set to support the special requirements of multiprocessing 当然这种支持包括多处理器可以共享外部设备和主内存,同时它通常还包括对指令系统的增加来支持多处理的特殊要求。
In this article , we introduce the design and implementation of key technologies in pems ( parallel embedded multiprocessing system ) , which is the operating system of the satellite - carried parallel computer system 本文以星载并行嵌入式计算机系统为背景,阐述其并行嵌入式操作系统pems ( parallelembeddedmultiprocessingsystem )中关键技术研究与实现。
To benefit from these features , we will develope task scheduling techniques that take account of the hierarchical structure and design on - chip multiprocessing supporting mechanisms to further reduce the program execution time 为了发挥架构特性以提升效能,我们将针对其阶层特性,开发工作排程技术,并开发多处理支援机构,以进一步降低程式执行时间。
It will feature communications acceleration , chip multiprocessing , and simultaneous multithreading . recent internal testing shows that power5 - based eserver systems are expected to offer four times the performance of the first power4 - based servers 这种芯片具有很多特性,例如通信加速、芯片多处理器、同步多线程,等等,据报告声称其性能超过power4芯片50 %到100 % 。
In smp also known as " tightly coupled " multiprocessing and a " shared everything " system , processors share memory and the i o bus or data path , and a single copy of the operating system controls the processors 在smp (也称为“紧耦合的( tightly coupled ) ”多处理和“共享所有”的系统)中,处理器共享内存和i / o总线或者数据通路,由单一的操作系统来控制这些处理器。
simultaneous processing by two or more processing units 同义词:parallel processing,
百科解释
Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. The term also refers to the ability of a system to support more than one processor and/or the ability to allocate tasks between them.
