C++11其实主要就四方面内容,第一个是可变参数模板,第二个是右值引用,第三个是智能指针,第四个是内存模型(Memory Model)。 相对来说,这也是较难理解的几个特性,分别针对于泛型编程,内存优化,内存管理和并发编程。 并发编程是个非常大的模块,而在诸多内容底下有一个基本的概念,就是并发内存模型(Memory Model)。

memory_order_relaxed: 只保证当前操作的原子性,不考虑线程间的同步,其他线程可能读到新值,也可能读到旧值。比如 C++ shared_ptr 里的引用计数,我们只关心当前的应用数量,而不关心谁在引用谁在解引用。 memory_order_release:(可以理解为 mutex 的 unlock 操作) ...
Linear Memory Model A linear memory model, also known as the flat memory model refers to a memory addressing technique in which memory is organized in a single contiguous address space. This means that the processing unit can access these memory locations directly as well as linearly. To bette...
“dynamic random access memory.” this is a type of ram (random access memory) which all computers have. dram is often used in pcs, laptops, smartphones, and tablets as well as many other types of computing devices. simply put, it provides temporary storage for files that are used when ...
Why is in-memory analytics important? Today, organizations in every industry rely on vast quantities of data to inform their operations, strategies and decisions. In addition to high volumes, they also have to contend with two other aspects of data: ...
in many cases, non-volatile memory can be upgraded or expanded. for example, in computers, you can often add more storage by installing additional hard drives or ssds. similarly, many devices allow for memory card expansion to increase storage capacity. how is non-volatile memory used in ...
The most commonly used RAM is still DDR4 memory, which also comes in multiple types and speeds. Generally, these memory sticks run at or above speeds of 2,400MHz. If you want to squeeze maximum performance out of your memory, you can get higher clocked RAM ranging from 3,200MHz all th...
