1. CPUs with the same core ID are Hyper-threading of the same core. (Physical ID and core ID is not necessarily consecutive but they is unique.) Any CPUs with the same core ID is hyperthreads in the same core.)2. CPUs with the same physical ID are the same CPU-encapsulated thread or cores. (Any CPU with the same physical ID is threads or cores in the same physical socket.)
① Number of physical CPUs:
- [Email protected] ~]# Cat/proc/cpuinfo | grep "Physical ID" | Sort | Uniq | Wc-l
② the number of cores per physical CPU (that is, the number of nuclei)
- [Email protected] ~]# Cat/proc/cpuinfo | grep "CPU Cores" | Uniq CPU Cores:4
This can figure out the logical CPU of your server is the number of physical * cores, and if your server is server2003, you can graphically see the number of logical CPUs in your resource manager.
- /proc/cpuinfo description with 6 Entries apply to multi-core and Hyper-Threading (HT) Technical checks: processor, vendor ID, physical ID, siblings, core ID, and CPU cores.
- * Processor Entry includes a unique identifier for this logical processor.
- * Physical ID The entry includes a unique identifier for each physical package.
- * Core ID The entry holds a unique identifier for each kernel.
- * Siblings Entry lists the number of logical processors in the same physical package.
- * CPU Cores The entry contains the number of cores in the same physical package.
- * If the processor is an Intel processor, The string in the vendor ID entry is Genuineintel.
