Problem with compare2 analysis #18

Closed brnorris03 closed 9 years ago

brnorris03 commented 9 years ago

Not sure why a multicore Xeon (/proc/cpu info below) caused this to happen.

I can reproduce this on Arya, but I am not sure if it's the same cause as yours.

I was comparing "cpu MHz" get from /proc/cpuinfo to make sure processors installed in the motherboard sockets are same model. Well, this is obviously wrong because of the CPU throttling. Maybe I should just check the model name.

On Arya right now:

$ cat /proc/cpuinfo | grep MHz
cpu MHz     : 1281.351
cpu MHz     : 1199.953
cpu MHz     : 1307.585
cpu MHz     : 1259.519

Mark as "Closed". Feel free to reopen for regression or if it is actually not fixed.
