嵌套级

However, the algorithms are somewhat more complicated, which is why we've used the adjacency matrix approach throughout this chapter.

它们的执行需要O(V^3)的时间级。这是因为在它们的实现中使用了三层嵌套的循环。

The paper summerizes several general pratical new techniques, such as the analyzers of program profiles, maximum potential parallelism, array privatizability, loop parallelism; the visualizers of the statement data dependence graph, procedural callgraph, loop iteration space graph and interactive tools of array privatization and unimodular transformation; the automatic techniques of array privatization combined data dependence and coverage, the computation of parallelizing unimodular transforming matrix for mult-nested loops, enhanced unimodular transformation with array reduction recognition, non-loop level parallelism revealing technique, dynamic dataflow analysis and optimization of cross-loop local cache reuses, etc.

本文从而概括了若干具有一般性的实用新技术，如：程序计算量分析、最大潜在并行性分析、数组私有化分析、循环并行性分析等动态程序分析技术；语句数据相关图、过程调用图、循环迭代空间相关图、交互数组私有化、交互幺模变换等可视化语义交互分析变换技术等等；总结了若干自动并行化新技术，如：结合相关和覆盖的数组私有化方法、对多层嵌套循环计算幺模并行化变换矩阵的循环幺模变换方法、结合数组规约识别增强幺模变换的技术、发掘非循环级并行性的技术、动态数据流分析技术、优化利用循环间Cache数据局部性的技术等等。

This should be performed by a two-level nested loop going though each index value for each segment.

由于要对每一段的每一个索引执行清空，所以这个操作应该是一个2级嵌套循环。

In addition, this policy is extendable for complicated system because process-level rejuvenation can be nested in application-level rejuvenation.

对于更复杂的系统，策略还可进一步嵌套进程级的恢复，从而具有一定的可扩展性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
