E.2.3. /proc/cpuinfo
This virtual file identifies the type of processor used by your system. The following is an example of the output typical of
/proc/cpuinfo
:
processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Xeon(TM) CPU 2.40GHz stepping : 7 cpu MHz : 2392.371 cache size : 512 KB physical id : 0 siblings : 2 runqueue : 0 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm bogomips : 4771.02
processor
— Provides each processor with an identifying number. On systems that have one processor, only a0
is present.cpu family
— Authoritatively identifies the type of processor in the system. For an Intel-based system, place the number in front of "86" to determine the value. This is particularly helpful for those attempting to identify the architecture of an older system such as a 586, 486, or 386. Because some RPM packages are compiled for each of these particular architectures, this value also helps users determine which packages to install.model name
— Displays the common name of the processor, including its project name.cpu MHz
— Shows the precise speed in megahertz for the processor to the thousandths decimal place.cache size
— Displays the amount of level 2 memory cache available to the processor.siblings
— Displays the total number of sibling CPUs on the same physical CPU for architectures which use hyper-threading.flags
— Defines a number of different qualities about the processor, such as the presence of a floating point unit (FPU) and the ability to process MMX instructions.
