similar to: cpuspeed causing hangs on warm boots

We have been seeing failures with CentOS 4.4 i386 (not x86_64) running compute-intensive programs on Tyan K8SRE (S2891) Tymotherboards, running Opteron 265's. This motherboard is used in the Tyan barebones box GT24 (B2881). We have these boards populated with 8GB of RAM, consisting of mixed 2GB and 1GB sticks. The symptom is that CPU-bound programs (may or may not be related to floating

It appears as cpuspeed is not running on my centos 5 box(s). One is a biostar motherboard Am2 6400+ the other is Asus am2 4800+. If I do "service cpuspeed stop" it says OK, If I do a "service cpuspeed start" is says OK. However at no time is cpuspeed running. /proc/cpuinfo only shows the cpu running at 1000 Mhz. If I manually run "cpuspeed -C & " I now have

On a new server's CentOS5 install, with nothing in the way of applications running yet, I noticed that the load average was sitting between 2 and 5 all the time, even though top told me CPU was 100% idle. Eventually I found that stopping the "cpuspeed" subsystem allowed the load average to drop down to near zero, as I would expect it to be. I have the default

Hi all, I think I've spotted a few stupidities (bugs) in the current version of kernel-utils (kernel-utils-2.4-13.1.80). I'm sure these are all propagated from upstream, but I hope someone could have a quick look to verify this and see if we either can push complaints upwards, or provide local fixes. The kernel-utils package provides several 'kernel-type' functions -

After upgrade my laptop, I discovered a low performance on it. The laptop is a 2,73GHz Intel centrino and from some kernels versions to now, it had a good performance, the cpu scaling worked fine. Now, I discover that forcing in /etc/sysconfig/cpuspeed the governors and/or max/min speeds, it don't want to run more quickly. The laptop boots fine with the correct speed (usual speed), but when

Hey, folks, Sometimes my workstation bogs down... slows to a crawl. Using gkrellm, it's obvious the CPU is the laggard. The top utility confirms: the load average gets up over 4 at times. But this occurs when cpu stepping pegs the speed at 600MHz. This processor is capable of 1.5GHz and when it's allowed to run at that speed, the load average is under 2, which is fine. So the

One problem I've discovered in cpuspeed is that there are drivers missing: # cd /lib/modules/2.6.18-194.8.1.el5/kernel/drivers/cpufreq # ll total 72 -rwxr--r-- 1 root root 14408 Jul 1 21:40 cpufreq_conservative.ko -rwxr--r-- 1 root root 16168 Jul 1 21:40 cpufreq_ondemand.ko -rwxr--r-- 1 root root 7624 Jul 1 21:40 cpufreq_powersave.ko -rwxr--r-- 1 root root 12524 Jul 1 21:40

Hi, cpuspeed did not start on all my systems. CentOS 5.4 x86_64 /etc/init.d/cpuspeed start (nothing happen) Something is missing ? Thanks in advance for any idea.

I have a desktop unit with a sempron 2500+ to play with. doing "more /proc/cpuinfo" indicates cpu Mhz as1044 not the 2500 I am familiar with cpuspeed. doing ps ax | grep cpuspeed resulting in nothing. I did service cpuspeed start. No errors reported. ps ax | grep cpuspeed resulted in nothing. I was going to do "killall -SIGUSR1 cpuspeed" to attempt to get 2500+ cpu speed. I

In older version of centos there was cpuspeed -d running that controlled current speed. In centos 5 it is set for on demand and cpuspeed is not running. I can startup cpuspeed and send it a signal SIGUSR1 to go full speed. This works. However, What is the correct or prefered method to control the cpuspeed in centos 5? THere are times when I want to tell the machine to go full speed and

Hi to the list, I am trying to find a way to painlessly move structured data back and forth between R and Matlab (also Octave). For this purpose I found the R.matlab package great help. I wish to use a Matlab -v6 MAT file as an intermediary format, because it is well read by both Matlab and Octave. It is also well read by 'readMat' function in R.matlab package, but that is where I run

what is the correct way to set an AMD64 CPU into performance mode at boot time? I have tried doing service network cpuspeed start, then killall -SIGUSR1 cpuspeed and this works but I cant get it working this way at boot. I have set chkconfig cpuspeed on but that didnt seem to help. I just want this particular machine to boot in performance mode and stay there. Jerry

[I sent this to the RHEL4 list - but maybe someone on this list knows more] I have a number of dual CPU and dual CPU/dual core Opteron systems that are used as compute servers. In an effort to reduce power consumption and reduce heat output, I would like to make use of the PowerNow! capabilities to clock back the CPUs when the machines are idle. These machines are running a 2.6.9-42 RHEL4 kernel
