一般现在很多电脑都是4核8线程,甚至是8核16线程的。那么这里的4核8线程是什么意思呢?和cpu是什么关系呢? 1. 查看电脑核心数 开始菜单-->运行-->cmd-->输入wmic-->输入cpu get* 并将底部滚动条拖拽到如下图所示位置 NumberOfCores:2(核数为2) NumberOfLogicalProcessors:4(逻辑线程数为4) 即这就是所谓...
cpu_count() function returns the number of CPUs in the system. The above Python code imports the multiprocessing module and then calls its cpu_count() function to get the number of CPU cores on the current system. The code then calls print() function to print the number of CPU cores on...

Recent trends of hardware advancement has switched from increasing CPU frequencies to increasing the number of cores. A significant implication of this change is that "free lunch has come to an end" -- you have to explicitly parallelize your codes in order to benefit from the latest progress ...
