Multiple trials is the basic concept of many parallel simulated annealing. It is to perform multiple trials at the same time to search acceptable solutions. The division simulated annealing with no communication and The clustering simulated annealing are two common types of parallel simulated annealing methods. The division simulated annealing with no communication makes each processor generate its own adjacent solution from its own current solution and compute the acceptance probability for a adjacent solution. Each of the processors searches solutions without communicating each other. Clustering simulated annealing makes each processor generate its own adjacent solution from a common current solution and compute the acceptance probability for each adjacent solution. Then, it decides which adjacent solution should be used to replace current solution according to a pre-specified rule.

许多平行模拟退火法之理论依据为多向试验，利用同一时间探索更多方向的试验来拓展搜寻的广度或深度，不进行沟通的分工模拟退火法(the division simulated annealing with no communication)以及丛集模拟退火法(the clustering simulated annealing)皆为平行化的模拟退火法，前者定义为各个处理器针对各自的起始解进行搜寻，产生各自的搜寻序列，在搜寻过程中处理器不进行任何沟通，各处理器仅针对自身之目前解进行搜寻；而后者定义为让所有处理器针对同一目前解进行运算搜寻各自的可能解，并各自决定其产出解之接受机率，最后根据事先决定之规则进行沟通比较，挑选其中一个可接受解取代目前解。

The 1MHz CPU might very well be faster, in practice, than the 2Mhz CPU - if it is more efficient or can process more tasks in each CPU cycle.

该处理器为1mhz很有可能更快，在实践中，比2mhz的中央处理器--如果这是更有效还是可以处理更多任务，在每个处理器周期。

In recent years, with the increasing of the processor's frequency and the parallel degrees in processor's instruction executing, the processor's memory access operations expand greatly and bring great pressure to computer systems.

近年来，处理器内核的工作频率及处理器内部指令执行并行度的不断增加，使单位时间内处理器内核的访存频度不断增加，导致处理器对访存效率的要求也越来越高。

In an asymmetric,shared-memory MP,processors are not equal.One processor is designed as the master processor,and the others are slave processors.

在非对称共享内存的多处理器中，各处理器地位不同，一个处理器设计成主处理器，其他则是从处理器。

Each user is a Field-bus control node.SCM MCS-51 is used as its main processor,and Neuron CMOS as its assistant processor.The two processors cooperate with each other.the main processor sam pling and controlling,and the assistant processor taking chang of communication.

The co-channel interference rejection filter for outputting a second input signal by removing co-channel interference from a first input signal; a first post processor for removing interference other than co-channel interference from the second input signal; a second post processor for removing interference other than co-channel interference from the first input signal; and a selection controller for selecting the output of the post processor which has less error by comparing the output of the first post processor with the output of the second post processor.

Uniprocessor designs have built-in bottlenecks.the address and data buses restrict data transfers to a one-at-a-time flow of traffic.the program counter forces instructions to be run in strict sequence.even if improvements in performance are achieved by means of faster processors and more instruction parallelism,operations are still run in strict sequence.however,in a uniprocessor,an increase in processor speed is not the total answer because other factors,such as the system bus and memory,come into play.

单处理器设计有内置的一些瓶颈。地址和数据总线限制数据传输的同时同地址的数据冲突情况。即使是通过更快的处理器和更多的并行指令，当然也包括维护，这些方式来提高的性能，程序的运行仍然被限制在严格的程式规则中。然而，在一个单处理器里，处理器速度的提高时不能完全解决这个问题的，这是因为像系统总线和存储器等其他因素同样在起作用。

Coprocessors Another way to increase the performance of a computer is through the use of a coprocessor, which is a special processor chip or circuit board designed to assist the processor in performing specific tasks .

协处理器另一种提高计算机性能的方法是使用协处理器，它是一种专门设计的处理器芯片或电路板，用来辅助处理器执行特殊任务。

But in a multiprocessors system,there may be several processors have read the same data,and then one processor will write it. This time,the copy of the data in the caches of other processors will be out of date.

但在多处理器系统中，由于多个处理器可能对同一数据块进行读操作，当某个处理器对共享的数据块进行写操作时，其它处理器的cache中该数据块的副本将成为过时的数据。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
