标题: 关于CPU绑定的设置
各位，HP-UX的主机（8CPU），绑定了4个，运行的时候，实际是从第二个（序号AFF_SPROC+1）CPU开始绑定的，而不是第一个，是这样的么？那我如何使用系统的第一个CPU呢？

AFF_SPROC    0             # Affinity start processor
AFF_NPROCS    4             # Affinity number of processors

AFF_SPROC 为1,2,3时
有什么特点? 发出来看一下

好像AFF_SPROC设0设1一个效果，后面都正常

AFF_SPROC    1             # Affinity start processor
AFF_NPROCS    4             # Affinity number of processors
