Subject: CPU stats on multi-core?


I played a bit more with my CPU using the --fork option and I'm a bit
unsure if it's working properly. I tried for example some unix MD5 hashes
on 8 cores and I get this stats:

0g 0:05:28:22 15.17% (ETA: 2014-07-01 23:11) 0g/s 6729p/s 20189c/s 20189C/s
0g 0:05:28:22 18.76% (ETA: 16:17:04) 0g/s 6755p/s 20266c/s 20266C/s
0g 0:05:28:22 2.32% (ETA: 2014-07-10 07:00) 0g/s 6837p/s 20511c/s 20511C/s
0g 0:05:28:22 20.52% (ETA: 13:46:56) 0g/s 6750p/s 20252c/s 20252C/s
0g 0:05:28:22 32.68% (ETA: 03:51:30) 0g/s 6666p/s 20000c/s 20000C/s
0g 0:05:28:22 0.04% 0g/s 7370p/s 22112c/s 22112C/s *)%^!&#&..*)%^!&%&
0g 0:05:28:22 4.15% (ETA: 2014-07-05 22:59) 0g/s 6817p/s 20451c/s 20451C/s
0g 0:05:28:22 16.10% (ETA: 2014-07-01 21:06) 0g/s 6862p/s 20588c/s 20588C/s

Well, I assume that each ETA is per virtual core, correct? If not, it could
complete more than 100% sum them all together.

The weird thing is, all my virtual cores are exactly the same, why they
have too much discrepancy from one to another?

I don't have other applications or programs running, however, we see for
example some cores that executed only 0.04% while other executed 32.68%.

Very weird, I was expecting them all to run pretty close one to the other.
Is there a way to fix it?

I tried even a bigger word-list and the discrepancy is so big that even
exceed 1 week.

0g 0:08:18:10 2.40% (ETA: 2014-07-14 21:03) 0g/s 6819p/s 20459c/s 20459C/s
0g 0:08:18:10 13.72% (ETA: 2014-07-02 23:37) 0g/s 6782p/s 20347c/s 20347C/s
0g 0:08:18:10 0.07% (ETA: 2015-11-06 15:13) 0g/s 7333p/s 22000c/s 22000C/s
0g 0:08:18:10 19.10% (ETA: 2014-07-02 06:34) 0g/s 6755p/s 20266c/s 20266C/s
0g 0:08:18:10 8.57% (ETA: 2014-07-04 11:59) 0g/s 6752p/s 20256c/s 20256C/s
0g 0:08:18:10 33.03% (ETA: 12:14:56) 0g/s 6693p/s 20079c/s 20079C/s
0g 0:08:18:10 10.33% (ETA: 2014-07-03 19:29) 0g/s 6754p/s 20262c/s 20262C/s
0g 0:08:18:10 15.49% (ETA: 2014-07-02 16:42) 0g/s 6729p/s 20187c/s 20187C/s

Is there a way to print a single stat line for all cores? I think it would
be less confusing.
