千万要买双核电脑

编软件要考虑如何利用双核CPU？感觉如何分配CPU不是应用程序要考虑的。多CPU系统靠操作系统来分配。多核的，我...

It's programmer's responsibility to improve application performance toward tagetted OS and CPU. When you write a software that runs very slow, what you tell to your boss? Your fault or Micorsoft's?

如果有性能问题是要进行tune，但不是针对多核cpu的。我觉得你不可能写出一段指定cpu（核）的指令，OS干啥去了？...

With performance tune, you have to consider features of OS and CPU architect. It's a part of application programmer's job, not OS's job. You don't write CPU instructuons. But you have to modify your code to fit for special OS and CPU.

If you write small app, computer is fast enough. If you write big app, that's part of your work.

OOP和OOD必然是多线程的。但并不是用这种方式开发的软件就一定是并行的。

This is correct. multi-thread not necessarily means parallel. Only parallel can claim the benefit of 2 CPU. Many parallelism can ba achieved by application. Not leaving everything to OS.
