让我们回到奔腾(Pentium)处理器的年代,那时候诸如 多核(multi-core)、虚拟CPU(virtual CPU)、逻辑CPU(virtual CPU)的概念还不存在,绝大多数的计算机在它们的主板上仅仅安装 单独的一块大容量芯片,我们称之为 微处理器、处理器或者 简单的CPU(microprocessor, processor or simply CPU)。只有少数的一些企业级计算机...
form online articles I read number of logical processors is equal to number of total threads, But as far as i know threads are subset of processes so but what thread means if it comes to hardware perspective ? Can anyone explain this !! My laptop has i3 processor with 2 cores..how OS...
At the operating system level, a physical quad-core processor would be shown as a 4 cpu computer. But these would be 4 logical CPUs or non-physical LCPUs. If the processor additionaly offers HyperThreading technology, commands such ashtopornprocwould indicate that there are 8 cpus in ...

线程(thread):是CPU执行的最小单元 OS scheduler:调度线程,决定哪些线程分配到CPU时间片 图示: image.png go Go runtime scheduler: 创建和管理所有的goroutine,绑定系统线程到logical processor,调度goroutine 到logical processor执行,包含一个goroutine全局待调度队列。
表示在相应的 SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX 结构中标识的处理器集之间的关系。语法C++ 复制 typedef enum _LOGICAL_PROCESSOR_RELATIONSHIP { RelationProcessorCore, RelationNumaNode, RelationCache, RelationProcessorPackage, RelationGroup, RelationProcessorDie, RelationNumaNodeEx, RelationProcessorModule, ...
If the processor additionaly offers HyperThreading technology, commands such as htop or nproc would indicate that there are 8 cpus in the system, but would perform lower than 8 cpus from a single octa-core processor without HyperThreading. 1 LCPU = 1 thread Finally, often we’ll find ...
二、GetLogicalProcessorInformation函数的使用心得 在MSDN上我们可以查到GetLogicalProcessorInformation函数的帮助—— http://msdn.microsoft.com/en-us/library/ms683194(v=vs.85).aspx GetLogicalProcessorInformation function GetLogicalProcessorInformation函数还牵涉到一些结构体和枚举—— ...
