Those things on Tianhe 2 (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

Various accelerator card heterogeneous computing

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
