similar to: cpuspeed on centos 5

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

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

I've been playing and comparing frequency scaling between AMD and Intel CPUs yesterday and there seem to be great differences between AMD and Intel and some gotchas. This is all on CentOS 5.2 with latest Xen kernels (which are supposed to be powersaving-enabled since 5.2). AMD: It seems once I get the AMD CPU to use the ondemand governor it works very well and very efficiently. But this

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

We are using CentOS-4.3 (x86_64) with Opteron servers, and noticed a problem with cpuspeed: If we reboot by doing "# reboot" or similar from a shell, the boot will hang not long after cpuspeed starts. The machine freezes: ctrl-alt-del doesn't work, and only pressing the reset button or a power cycle will restart the machine. If we reboot from power-up or by pressing the reset

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 -

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.

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

Hello, Using kernel: 2.6.18-92.1.13.el5.centos.plus the cpu throttling works as desired (see 2 traces below) ------------- trace snips -------------- dmesg | grep -i pow ACPI: SSDT (v001 PTLTD POWERNOW 0x00000001 LTP 0x00000001) @ 0x3fff9b40 powernow-k8: Found 1 AMD Athlon(tm) 64 X2 Dual Core Processor 4600+ processors ( 2 cpu cores) (version 2.20.00) powernow-k8: 0 :

[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

Hi All, I had a box centos5 AMD64 X2 4200+, Asus motherboard, Nvidia 7100 video card, 512M, when playing a video at 1080p it did well but had a couple times went out of sync. So amd dropped its price and I got a 5200+, gigabyte motherboard, Nvidia 7100 video card, 512M. This FASTER system is actually slower. The video is WAY behind on sync. I have looked at the X config they are the same. I

Hi, Although I set check.names to FALSE in read.table, the duplicate names get modified.

Hey all, Since moving a 4.3 x86-64 install from a single athlon64 to a new dual core AMD cpu it would appear that cool'n quiet is having trouble as is shown in the system logs; powernow-k8: ignoring illegal change in lo freq table-2 to 0x2 powernow-k8: transition frequency failed Any ideas ? Cheers, Brian.

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
