Is it still worth to invest time into OpenMP implementations?

Since clang/llvm has no plan to support OpenMP any time soon, and Intel is going far away down the road of TBB library. Is it still worth to implement multi-thread scientific libraries (I am working on ccv: http://github.com/liuliu/ccv) on top of OpenMP? Despite all the criticisms, my experience with OpenMP is quite happy (it is super easy to use, and the performance gain is reasonable). But i

投入OpenMP实施还是值得的吗?

由于clang / llvm没有计划在短期内支持OpenMP,而且英特尔正走在TBB库的道路上。 在OpenMP之上实现多线程科学库还是值得的(我正在研究ccv:http://github.com/liuliu/ccv)? 尽管所有的批评,我对OpenMP的经验是相当高兴的(它是超级简单易用,性能增益是合理的)。 但是,如果它是一种垂死的技术,C中更容易多线程的替代品是什么? (不是pthread,而TBB是C ++的东西)。 谢谢! OpenMP是活着的,很好,甚至将它扩展到

mingw+libarchive: cross compiling linker error

I'm trying to cross compile a tiny program under Linux for win32. It uses libarchive, which is available in for mingw on my fedora 23 installation (all installed through dnf), but I get lots of linker errors.

Why doesn't ConcurrentBag<T> implement ICollection<T>?

I have a method which takes an IList<> and adds stuff to it. I would like to pass it a ConcurrentBag in some cases, but it doesn't implement IList<> or ICollection<>, only the non-generic ICollection, which doesn't have an Add method. Now, I see why it can't (maybe) implement IList - it's not an ordered collection so it won't make sense for it to have an i

为什么ConcurrentBag <T>不实现ICollection <T>?

我有一个方法需要IList <>并添加内容。 我想在某些情况下将它传递给一个ConcurrentBag,但它不实现IList <>或ICollection <>,只有非泛型ICollection没有Add方法。 现在,我明白了为什么它不能(可能)实现IList - 它不是一个有序的集合,所以它没有任何意义,因为它有一个索引器。 但是我没有看到任何ICollection <>方法的问题。 所以为什么? 而且,在.NET中是否有一个线程安全的集合,它实现

XML Serialization for collection types

Does anyone have an implementation for object serialization that support collections, such as ICollection, IEnumerable, IList, IDictionary? Below is my implementation, and it's not so clean. [Serializable] public abstract class IXmlable { public virtual string ToXml() { Type type = GetType(); PropertyInfo[] properties = type.GetProperties(); string ret = "&

XML序列化用于集合类型

有没有人有支持集合的对象序列化实现,例如ICollection,IEnumerable,IList,IDictionary? 下面是我的实现,它不是那么干净。 [Serializable] public abstract class IXmlable { public virtual string ToXml() { Type type = GetType(); PropertyInfo[] properties = type.GetProperties(); string ret = "<" + type.Name + ">"; foreach (PropertyInfo item in properties

How do I mark a method as obsolete or deprecated?

如何将过时的方法标记为废弃或使用C#废弃? The shortest way is by adding the ObsoleteAttribute as an attribute to the method. Make sure to include an appropriate explanation: [Obsolete("Method1 is deprecated, please use Method2 instead.")] public void Method1() { … } You can also cause the compilation to fail, treating the usage of the method as an error instead of warning, if the method is cal

如何将方法标记为过时或弃用?

如何将过时的方法标记为废弃或使用C#废弃? 最简单的方法是将ObsoleteAttribute作为属性添加到方法中。 确保包含适当的解释: [Obsolete("Method1 is deprecated, please use Method2 instead.")] public void Method1() { … } 如果方法是从代码中的某处调用的,则也可能导致编译失败,将该方法的用法视为错误而不是警告: [Obsolete("Method1 is deprecated, please use Method2 instead.", true)] 要标记为过时并带有警

Detecting audio silence in WAV files using C#

I'm tasked with building a .NET client app to detect silence in a WAV files. Is this possible with the built-in Windows APIs? Or alternately, any good libraries out there to help with this? Audio analysis is a difficult thing requiring a lot of complex math (think Fourier Transforms). The question you have to ask is "what is silence". If the audio that you are trying to edit

使用C#检测WAV文件中的音频沉默

我的任务是构建一个.NET客户端应用程序来检测WAV文件中的静音。 这可能与内置的Windows API有关吗? 或者,还有一些好的图书馆可以帮助解决这个问题? 音频分析是一件困难的事情,需要很多复杂的数学(思考傅里叶变换)。 你要问的问题是“什么是沉默”。 如果您尝试编辑的音频是从模拟信号源捕获的,则可能是没有任何静音......它们只会是软噪音区域(线路嗡嗡声,环境背景噪音等)。 所有这一切,一个应该工作的算法将
