wsx02 2012-06-25 21:28:261. when multiple threads run in parallel on a multicore system, would the
more threads for the same task always finish earlier when the number of
threads is less than the number of cores? why?
我想應該是錯的 可是不知道該怎麼解釋 不知道有沒有什麼例子
2. in what situation, applications using kernel thread would not always have
a better performance than using user thread?
我目前想到的是建立和管理user thread會比kernel thread還快
可是想不到有什麼實際的例子
謝謝
