我创建了一个生活游戏：（https://gitlab.com/kiroma/gol-proto），我尝试使用可扩展线程池进行多线程处理。从理论上讲，它应该尽可能多地使用所有内核，但是无论模拟大小如何，该平台（在Linux机器，2c / 4t和Windows机器4c / 4t上进行测试）都不会使用超过60的内核。占整个CPU运行时间的百分比。
使用自旋锁而不是等待条件变量进行同步来更改进程优先级，排除诸如缓存争用之类的悲观行为。
对于该项目，我创建了自己的线程池类，称为工作池：（https://gitlab.com/kiroma/gol-proto/blob/master/workpool.cpp）。像将 #PAGESPEED

与std::condition_variable_any一起使用有一些奇怪之处，但是我尝试了其他更常规的方法，结果大致相同。
