In fact, as long as

You can get the current number of CPUs ...
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.

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.

2 Introduction and implementation of consumer Stack
2.1 Structure of a stack
Elastic stack microserver is a set of development kits provided by Echelon. Its structure is as follows:
Figure 1 Producer stack structure
The figure shows that the communication between the master processor and the consumer stack
almost as fast as the 2.66 GHz Xeon/Opteron chip, or 1.5 GHz Itanium 2 is about as fast as 4 GHz Xeon/Opteron. The computing speed of the CPU depends on the performance indicators of the CPU pipeline.
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?
