存储器模型(memory model)又称为存储一致性模型。用于定义系统中对存储器访问需要遵守的原则,只要软件和硬件都遵循该原则,就能保证多核程序能运行得到确切的结果。Memory model一致性问题来源于:编译期乱序、执行期乱序,以及Cache不同步。 个人理解:内存模型与CPU Cahce一致性:由于CPU core对store buffer/invalidate
C++11引入memory model的意义在于我们可以在high level language层面实现对在多处理器中多线程共享内存交互的控制。我们可以在语言层面忽略compiler,CPU arch的不同对多线程编程的影响了。我们的多线程可以跨平台。 内存模型 为C++ 定义计算机内存存储的语义。可用于 C++ 程序的内存是一或多个相接的字节序列。内存中的...

Ensuring Code Model Consistency If parts of newlib are going to be replaced with an external library (such as withlibgloss-htiffor Berkeley Host-Target Interface), you should take care to ensure that both newlib and the external library are built using the same code model. For more information...
Modern concurrent programming languages like Java and C# have a programming language level memory model; it captures the set of all allowed behaviors of programs on any implementation platform — uni- or multi-processor. Such a memory model is typically weaker than Sequential Consistency and allows ...
The following Simulink model uses this S-function. sfcndemo_stvctf The S-function demonstrates how to work with the solvers so that the simulation maintains consistency, which means that the block maintains smooth and consistent signals for the integrators although the equations that are being ...
