How to identify the number of physical CPUs, a few cores, is hyper-threading or multi-core
Judge the basis:
1. CPUs with the same core ID are the same core hyper-threading.2. CPUs with the same physical ID are the same CPU-encapsulated threads or cores.
English version:
1.Physical ID and core ID are not necessarily consecutive but they unique. Any CPUs with the same core ID are hyperthreads in the same core.2.Any CPU with the same physical ID are threads or cores in the same socket.

chip can perform almost as fast as the 2.66 GHz Xeon/opteron, or 1.5 GHz Itanium 2 is about as fast as 4 GHz Xeon/opteron. CPU's operating speed also depends on the CPU's pipeline of various aspects of performance indicators.
Of course, the frequency and the actual speed is related, can only say that the clock is only the performance of the CPU one aspect, and does not represent the overall performance of
to study the tools to use, or worry that the replacement of components takes too long, even if the chassis is opened for the first time, according to the illustration of the chassis backplane, it can also be completed in dozens of seconds to several minutes, which sounds really good.

Of course, the clock speed is related to the actual computing speed. It can only be said that the clock speed is only one aspect of the CPU performance, not the overall performance of the CPU.

is a two-dimensional array [don't tangle, in order to make it easier for me to convert it to JSON], where type has only two values of 1 and 2,Now you need to move the type=1 element into the $new array, type=2 to the $old array.
Is there any way besides using the loop?

For many enterprise users, performance is not the primary factor for server selection. The most important indicator is low power consumption and capital budget. AMD's latest haolong 4100 series processor is developed and designed for such users. The 4100 series is a low-level version of The Magny-Cours codenamed mainiku core haolong 6100 series processor. Haolong 6100 has two versions: 8-core and 12-core. In contrast, the "Lisbon" haolong processor is only a single core.
