Qualcomm ARM CPU vs. Intel x86 CPU Performance ComparisonWith the advent of the mobile internet era, arm-based CPUs such as Qualcomm (Qualcomm), Texas Instruments (Texas Instruments) have received more and more attention, while the former king's Intel x86 architecture seems to be struggling in the mobile internet due t
The quad-core is a processor core that has four functions on one processor based on a single semiconductor. In other words, four of the physical processor cores are integrated into one core. The difference between the quad core and the dual core is that on multitasking, the CPU of the four cores open four programs to open four programs faster than the dual
Cat/proc/cpuinfo: you can see the actual number of cpu cores in detail. it should be the cpucores parameter value, the number of physical CPUs, and the number of non-repeated physicalids. There are several [user @ localhost ~] # Cat/proc/cpuinfoprocessor nb

Requirement
During programming, especially in program development involving the system environment, we may need to dynamically obtain the number of available CPU cores in the current machine. For example, when we need to perform parallel computing, we may determine the degree of Parallelism Based on the number of CPU cores
