I have a Sun server with 4 CPUs. How can I verify if all 4 are being used? When I use top, it doesn't seem to break it down into 4 cpus, should it? example: load averages: 1.14, 1.06, 0.88; up 27+03:16:09 14:39:30 148 processes: 145 sleeping, 1 running, 2 on cpu...

What Are the Differences Between Itanium and x86_64 CPUs?

This is definitely a "stupid" question, but I can't think of anywhere else to ask it, so here goes. My knowledge of CPU history on big iron machines starts with the last DEC Alphas, a short stint with Sun servers, PA-RISC and Itanium, Intel 486s on the desktop before that, and Motorola 68000 CPUs...

uptime, load average, and # cpus

I was told that there is a correspondance between the number of cpus, the load averages, and when the cpus reach 100% capacity. I have 4 cpus and said that once the numbers hit 4.00, my CPUs are 100% at capacity. load average: 0.08, 0.09, 0.11 Is that correct? Thank you

cpufreq-info

cpufreq-info(1) 														   cpufreq-info(1)

NAME

       cpufreq-info - Utility to retrieve cpufreq kernel information

SYNTAX

       cpufreq-info [options]

DESCRIPTION

       A small tool which prints out cpufreq information helpful to developers and interested users.

OPTIONS

       -c --cpu <CPU>
	       <CPU> number which information shall be determined about.

       -e --debug
	      Prints out debug information.

       -f --freq
	      Get frequency the CPU currently runs at, according to the cpufreq core.

       -w --hwfreq
	      Get frequency the CPU currently runs at, by reading it from hardware (only available to root).

       -l --hwlimits
	      Determine the minimum and maximum CPU frequency allowed.

       -d --driver
	      Determines the used cpufreq kernel driver.

       -p --policy
	      Gets the currently used cpufreq policy.

       -g --governors
	      Determines available cpufreq governors.

       -a --related-cpus
	      Determines which CPUs run at the same hardware frequency.

       -a --affected-cpus
	      Determines which CPUs need to have their frequency coordinated by software.

       -s --stats
	      Shows cpufreq statistics if available.

       -y --latency
	      Determines the maximum latency on CPU frequency changes.

       -o --proc
	      Prints out information like provided by the /proc/cpufreq interface in 2.4. and early 2.6. kernels.

       -m --human
	      human-readable output for the -f, -w, -s and -y parameters.

       -h --help
	      Prints out the help screen.

REMARKS

       You can't specify more than one of the output specific options -o -e -a -g -p -d -l -w -f -y.

       You also can't specify the -o option combined with the -c option.
