[luau] CPU states in top?
I just got a 1u rack mount dual Xeon system from these guys: http://www.swt.com/thin4.html I was looking at top and noticed that it lists 4 CPU states, where I'd generally figure there'd be one per CPU. Any ideas why this would be? I opened it up to be sure, and yep, there's only 2 CPUs. Thanks, -Charles

I think I read something somewhere (helpful, I know) that mentioned that the Linux kernel can treat the P4s with hyperthreading as virtual dual processors. I haven't gotten a chance to play with these processors yet, so I can't tell you for sure. Chris

Windows reports 2 per CPU as well with the Zeons. With a dual CPU box you will see 4 in the task manager. -Matt

I was thinking the same, but only you have access to such nice toys Charles, so I can't check... What kind of stats is tops reporting vs. whats on the system? This may clue you in to whats going on with the Xeon's.
