How to identify the number of physical CPUs, the number of cores, whether hyper-threading or multi-core Jun.04, 2009in server judgment basis: 1. CPUs with the same coreid are hyper-threading of the same core. 2. A cpu with the same physicalid is a thread or cores encapsulated by the same cpu. English version: 1.

I believe everyone knows about Tianhe 2, ranking first among the top 2013 and 2014 top500, which is one time faster than the top 2nd Titan, what kind of architecture does Tianhe 2 use to achieve this capability? Let's take a look at it. Tianhe No. 2 Model for TH-IVB-FEP, using the central processor and co-processor computing architecture layout: Tianhe 2 has a total of 16,000 computing nodes, each of which is equipped with two Xeon E5 12 core central

Heterogeneous computing:Heterogeneous computing uses different types of processors to handle different types of computing tasks. Common computing units include CPUs, GPGPU, GPDSP, Asics, FPGAs, and other types of core processors.There are many accelerator cards or coprocessors that are used to increase system performance, which are common:GPGPU is the most common accelerator card, connected by PCI-E. The GPU was first used for graphics processing cards, the graphics card, and then slowly develop

The number of Linux CPUs is judged by/proc/cpuinfo.Same Physical ID: determines a physical processorIf "siblings" and "CPU cores" are consistent, hyper-threading is not supported, or hyper-threading is not open.If "siblings" is twice Times "CPU cores", then hyper-Threading is supported and Hyper-threading is turned on.In fact, just#include Long num = sysconf (_SC_NPROCESSORS_ONLN);You can get the current number of CPUs ...Basis of judgment:1.

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
