Even so ,you should consider jump-starting your efforts by beginning with someone else's working configuration ,since the source code of their version will be available for that purpose .

传统的方法是讲授一些算法，然后用具有明显并行性的程序设计语言明确地表达它们。

The parallelism to read and write file data is promoted because data striping technology is used. Also the response performance of the system is improved.

采用文件数据分块存储技术，提高了文件数据读写的并行性，从而改善了系统的响应性能。

And the prospect for the future of genetic algorithm in solving TSP is made.

Beside, ReadyBoost also leverages the inherent parallelism of having two sources to read data from.

旁边，还充分利用的ReadyBoost所固有的并行性有两个来源，从读取数据。

In the past research, instruction clustering pay more attension on instruction parallelism, and pass the register pressure to register allocator. In this paper, the authors clustered instruction through runtime inspection of the register command pressure.

在以往的研究中，软件流水之前的指令分簇会更多地考虑指令并行性，往往会把寄存器的压力交给寄存器分配阶段，当物理寄存器不够分配时会造成寄存器溢出。

To compute moments of a twodimensional image, a large number of multiplications and additions are required in a direct approach.

它的基本思想是利用数据并行性将一个二维图像矩分解成垂直矩和水平矩，然后在LS MPP协处理器上利用级联求和算法在垂直方向和水平方向分别计算二维图象的多个垂直矩和一个水平矩。

In this chapter, we analyze a parallel algorithm for the computation of twodimensional image moments on a linear array.

这个算法极大的利用了计算的并行性，理论计算复杂度为O，加速比是〓。
