Question 620
At the Northbridge public-sector AI program, a team enables RDMA over Ethernet without planning congestion signaling or suitable loss characteristics and sees inconsistent transfers. How should the team reduce the chance of the issue recurring?
Explanation
Correct Answer
The continuing risk is that RDMA over Converged Ethernet can be sensitive to congestion and network-loss behavior. To sustain the correction, review switch and NIC congestion counters as traffic grows. This directly addresses the reported issue at the Northbridge public-sector AI program.
Incorrect Answers
That practice helps control a different risk: many AI services still use conventional network protocols even if some GPU transfers benefit from specialized paths. The recurring control here should be to review switch and NIC congestion counters as traffic grows. For the Northbridge public-sector AI program, the priority is to design appropriate RoCE Ethernet congestion management including supported ECN and priority controls where necessary.
The alternative suggests that the team monitor regional capacity requirements as training scale increases; it would not directly prevent the observed issue from returning. For the Northbridge public-sector AI program, the priority is to design appropriate RoCE Ethernet congestion management including supported ECN and priority controls where necessary.
This maintenance work is reasonable for optical transceiver compatibility. The continuing exposure described here is that RDMA over Converged Ethernet can be sensitive to congestion and network-loss behavior. For the Northbridge public-sector AI program, the priority is to design appropriate RoCE Ethernet congestion management including supported ECN and priority controls where necessary.
