并行编程:需要帮助！ [英] parallel programming : NEED HELP !

问题描述

伙计们，我真的是个大问题，由于该站点上的专家数量众多，您是我的最后机会.
我是计算机专业的学生，​​今年我将完成学业.作为项目，我使用C语言开发了一个程序，该程序允许计算并行程序的执行时间"，我的第一个(也是我的大问题)是我不知道从哪里开始，第二，我不知道是否必须找到解决方案的类型，我澄清:我对并行编程有很好的了解，但是对这种时间估计"却不了解，因为我不知道解决方案将是一个数学公式或就像总是时间=计算时间+交流时间)，第三次不幸的是，我发现可以帮助我的资源并非全都是免费的(哦，是的，另一个可怜的男孩，我不以为耻，因为我打算这样做)将来成为好人，这对我很重要)而自由者的信息非常匮乏.因此，请各位先生们能帮助我，我将永远感激不尽(我要求提供论坛，站点，文档，书籍，代码，解释，类似的项目……但请大家记住，它必须是免费的，因为我的学习经历了我每一分钱)非常感谢预先匹配.

Hi, guys I’m really in big problem and you are my last chance due to the important number of expert in the site.
I am a student in computing and this year I am finishing my studies. I had, as project , developing a program ,using C language, that permits the " Calculation of time of execution of parallel programs ",My first(and my big one) problem is that i don''t know where to Begin, My second is that i have no idea about the type if solution that i have to find out, i clarify : I have good knowledge in parallel programming but not this "time estimation" because i do not know is the solution going to be a mathematical formula or just like always time=time of calculation+time of communication) and third Ununfortunately I found that the resources that can help me they are all not free (oh yes another poor boy and I am not ashamed of telling it beacause I am planning to be a good man in future this is what count for me )and the free ones are very poor in information. So please can anyone of you gentleman help me i will be forever grateful (I’m asking for forums, sites,documents,books, codes,explanations, a similar projects... but please guys remember it must be free besause my studies took me every cent) Thanks very match in advance.

PS: excuse me if there are spellings or grammar mistakes,Mainly i speak French and English is my second one. Sorry for everyone who met problems while reading my article ^^

推荐答案

通常，要研究算法的性能，您应该首先实现算法，而不是实现函数那

-查询计时器
-调用算法，为其提供所需的测试数据
-再次查询计时器

两个查询的值之间的差是经过的时间.
关于计时器，您可以在此处资助一些有用的文章

或通过Google"Windows高分辨率计时器".

In general, to study the performance of an algorithm you should fist implement the algorithm and than implement a function that

- queries a timer
- call the algorithm giving it the required testing data
- queries the timer (again)

The difference between the values of the two queries is the elapsed.

or by google "windows high resolution timer".
