Harnessing 3200Gbps Network (8): Bus Topology

In the previous chapter, we achieved a transmission speed of 97.844 Gbps on a single network card. In Chapter 2, we introduced that the best transmission speed is achieved by pairing GPUs with nearby network cards. Before we start using multiple network cards, we’ll first clarify the machine’s system topology in this chapter. We’ll name this program 8_topo.cpp. Obtaining System Topology To obtain…
