If your an Intel fanboy please stop reading and go troll somewhere else. This is a legitimate attempt to start an honest discussion about the "current state of things" with regards to which CPU manufacturer makes the most CPUs that offer "the best bang for the buck".
I have been researching the purchase of a new CPU.
My manager has asked me to find out how many CPUs we own against how many CPUs are actually being used. The question might be simple but I am confused with the outputs from some of the commands I ran. In this regard, I have the following questions.
1. Are LPARs and Logical CPUs the same?
2. When I look at my software license, it indicates that we are licensed for 10 Logical CPUs.
I have a dual-core Core i3 on my laptop, and System Monitor gives usage statistics for 4 different "CPUs". I'm assuming that the 4 CPUs the OS recognizes are actually the cores in the processor, and the 4 "CPUs" are due to the hyperthreading, which I understand creates a virtual core for every physical core.
Modern CPUs are quite complicated and to understand the performance profiling often needs to be used. The CPUs have performance monitoring units (PMUs) that allow to count and sample a wide variety of events. Linux perf provides an interface to the PMU.
