4 core vs 2 core NaCl2009-01-26 17:41:39

Even more and more 4 core CPUs are on the market, I was told there are not many programs actually can take advantage of all 4 cores. If this is true, does it mean 4 core CPU is no much better and a high clock speed 2 core (at least for now)?

完全正确。多核处理器只有在并行计算时才有优势。

you don't need parallel algorithm to take advantage

完全同意你的看法， 有事实证明：

你说的是让一台机器同时执行多个互不相干的独立任务。

Mac Pro＋OS X 10.5＋Parallel 算服务器还是个人电脑呢，哈哈

工作分配并不完全是操作系统的事。

你仔细想想，Mac Pro＋OS X 10.5真的利用多核处理器么?

咱们啥时候谈过全时全并行计算，不是在谈普通PC嘛。答案：是的

换个提法：通过某些技巧安排，完全可以充分利用多core优势。

个人电脑不太可能有这种情况？
