Denis, |

That sounds like the server at work I'm using, nice machine.. |

Anywya, there was a thread on something like this in the forums, and it |
5 |
basically turned out to be the SMP Gentoo kernel, the guy went to |
6 |
vanilla kernel and everything worked just dandy. Can you verify this? |
7 |
Maybe the kernel team needs to focus on something? |
8 |
|
9 |
Can you run 4 threads of Seti@Home to see if it kills the machine? That |
10 |
should be a good test as it will saturate your CPUs |
11 |
|

Best, |

Subject: [gentoo-dev] SMP kernel halts system - hyperthreading?? |

Dear gentoo-dev, |
24 |
|
25 |
If some of you recall, I wrote to the list about a system halt resulting |
26 |
from running C++ codes and it possibly having to do with nVidia graphics |
27 |
or XFree 4.2.1. |
28 |
|
29 |
Well, the problem persists in text mode also. It happens when 3 or more |
30 |
CPU-intensive processes run simultaneously on the machine. I have an |
31 |
SMP |
32 |
kernel (2.4.19-gentoo-r7) with 2 Intel Xeon 2.2-GHz processors equipped |
33 |
with hyperthreading technology. |
34 |
|
35 |
I have 4 processors initialized at boot time, and 4 processors show up |
36 |
in |
37 |
"top". This is probably because of hyperthreading, as otherwise there |
38 |
should be only two. |
39 |
|
40 |
How do I turn off hyperthreading? Do you think hyperthreading is what's |
41 |
breaking my system and it could be more stable without hyperthreading? |
42 |
Can a certain process be confined only to a certain processor? |
43 |
|
44 |
Thanks for any help! |
45 |
