First, the concept① Physical CPUThe number of CPUs in the actual server slot on the physical CPU, the number of physical IDs that can be repeated is several② Logical CPU③CPU Number of coresThe number of chipsets that can process data on a CPU, such as the current i5 760, is
Linux distinguishes physical CPU, logical CPU, and CPU cores (I) concept www.2cto.com ① physical CPU the number of physical CPUs in the actual Server slot the number of physical CPUs, there are several non-Repeated physical IDs. ② logical CPU Linux users are certainly familiar with the/proc/cpuinfo file. it lists the specifications of processor 0-n separately. It
How to learn more about CPU information in Linux systems. Of course, it is checked by Cat/proc/cpuinfo, but for example several physical cpu/several cores/several threads, these questions how to determine. After viewing, my development machine was 1 physical cpu,4 cores 8 threads, Intel (R) core (TM) i7 CPU 860 @ 2.80GHz recorded, judged by the process and knowle
the relationship between the number of physical CPUs, the number of cores, and the number of threads.

of Intel quad-core E3 1230v2? AMD technology remains at 32 nm, and Intel has already entered the 22nm era. In addition, AMD architecture is not as good as Intel, leading to a large gap in single-core performance. AMD relies on the number of heap cores to compete with
information in the Cat/proc/cpuinfoprocessor The ID of the logical processor. ID of the processor that physical ID physically encapsulates. the ID of the core ID for each key.

[1] Physical CPU: The number of CPUs on the slot in the actual server.
Number of physical CPUs: There are several physical IDs that can be counted without duplicates.
