并行执行

Many embedded systems run autonomously and need to execute many tasks in parallel with specific timing requirements.

许多嵌入式系统自动运行并且需要并行执行许多有特定定时要求的任务。

To prediting the parallel execution time of the parallel program that is composed of a number of sub-tasks, each of which has identically, independent distributed random execution time, this paper presents the parallel execution time predicting method which is based on the Johnson distribution.

为解决由具有独立同分布随机执行时间的子任务组成的并行任务的执行时间预测问题，提出了基于Johnson分布的并行执行时间预测方法。

The method can be used not only for predicting the maximum or minimum parallel execution time, but also for solving any problem about the maximum or minimum of identically, indentical distributed random variables.

这种方法不仅适于解决"最大"或"最小"的并行执行时间预测问题，而且适于任何求独立同分布随机变量的最大值与最小值问题。

A thread is a sequence of instructions that can be executed in parallel with other threads .

一个线程是一个可以和别的线程并行执行的指令序列。

For pioneering contributions to the theory and practice of optimizing compiler techniques that laid the foundation for modern optimizing compilers and automatic parallel execution.

获奖原因是她对于优化编译器技术的理论和实践做出的先驱性贡献，这些技术为现代优化编译器和自动并行执行打下了基础。

Therefore, this approach is well suited for parallel computation on a parallel computer or system.

因此，波形松弛算法具有良好的并行执行特性。

Workflow executive service The workflow executive service is a core of a workflow system, and it only supports sequent execution and parallel execution of activities.

目前的工作流系统只支持活动间的顺序和各自独立的并行执行，而不能支持活动间的相互关联的并行执行。

After packing the parallel executable tasks in the task graph, the PEPs are generated in which the communication and synchronization primitives are inserted automatically.

对该任务图中的可并行执行任务进行并行封装，形成若干可并行执行包，并在其中自动地插入通信与同步原语。

Through statical analysis of the data dependency between subgoals, combined with the analysis results of the characteristic of parallel execution and the impacts of side-effects, the intelligent backtracking points with conditions can be found in precompiling time. At run time, the intelligent backtracking points for failed goals can be determined by variable testing and run state testing. Using intelligent backtracking scheme, a lot of redundant backtracking can be avoided and the execution efficiency of programs is improved.

同时，我们在深入研究顺序智能回溯及并行平凡回溯机制的基础上，独立提出了一种并行智能回溯机制，通过静态时对子目标数据相关性的分析，结合对并行执行特性及付作用目标对智能回溯的影响等因素的分析，产生带条件的智能回溯点；动态时通过对变量及当前运行状态的简单测试，确定失败目标的智能回溯点。

Array privatization is one of the most effective loop transformations for the exploitation of parallelism. This transformation technique privatizes arrays according to the information of the data dependence analysis, which eliminates the memory-related dependences, i.e. anti and output dependences, to make the loop execute parallel.

数组私有化是开发并行性最有效的循环变换技术之一，它以数据依赖关系分析为依据对数组进行私有化，消除循环中的存储关联数据相关，即反相关和输出相关，使循环可以并行执行。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
