如何获取机器的CPU的物理个数
请教各位，如何获取机器的CPU物理个数，最好是用WMI或API的方式。谢谢 udf或者源码区去找 2# netegg找过很多，大部分是返回CPU的内核或超线程的数量，而不是实际的CPU个数。 本帖最后由 netegg 于 2009-9-28 22:56 编辑
你指的数量是可见的物理个数？也就是多核cpu只认为是一个？ 不对，如果不是内核数的话，windows自己好像都没有，你看自带的设备管理器，双核cpu也是认定的两个 你指的数量是可见的物理个数？也就是多核cpu只认为是一个？

是的,就是您的意思. 用erverest可以看出CPU的物理个数,确实不想只读出内核的个数. SetupDi*函数族应该可以判断出CPU的物理个数，但不会像everest那样读取准确。

}以代码为C++，我不懂，谁能帮忙转化为autoit的，或弄个UDF，谢谢。 本帖最后由 netegg 于 2009-12-16 13:52 编辑

这段脚本效果还是不太好，有的CPU还是不能实际检测。
