Bandwidth flucation in Nvlink connection (p2pBandwidthLatencyTest)

Question

The topology of my cluster is demonstrated in the first pic:

However, running the p2pBandwidthLatencyTest, I got an unpredicted result. The bandwidth between 2 and 3 is obviously lower than 0 and 1. Is there anyone who knows the possible reason?

what sort of system is this? Is it a Dell C4130 or C4140? – Robert Crovella Nov 06 '18 at 15:11 — Robert Crovella, Nov 06 '18 at 15:11

Per to the technical support, it is due to the concrete hardware placement difference.
