CPU缩放:当前频率如何超出最小 – 最大范围?

我试图理解为什么我的CPU不能以更高的频率运行( 相关链接 ) 有人可以解释一下,当定义最小值和最大值时,有效值最终会超出该范围吗? $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 3267000 $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 3300000 $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq 1199960 $ cpupower frequency-info analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 0.97 ms. hardware limits: 800 MHz – 3.30 […]

系统监视器显示不正确的CPU数量

我目前正在运行Ubuntu 14.04.2桌面。 当我期待56时,系统监视器工具向我显示32个 CPU。 我应该担心吗? System Monitor的屏幕截图: 如您所见,它显示32个CPU。 输出lscpu : ~$ lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 56 On-line CPU(s) list: 0-55 Thread(s) per core: 2 Core(s) per socket: 14 Socket(s): 2 NUMA node(s): 2 Vendor ID: GenuineIntel CPU family: 6 Model: 63 Stepping: 2 CPU MHz: 1337.882 BogoMIPS: […]
