InfiniBand is a proven networking technology for HPC and AI clusters. Which of these are recognized advantages that make InfiniBand suitable for these demanding workloads?
Select all correct answers, then click Submit.
Short Explanation
A, D, E, and F are correct advantages. C is false (high latency is bad, not good). B is misleading — offloading is CPU-level (CPU doesn't manage transfers), not GPU-level. InfiniBand excels at: low latency, high reliability, CPU offloading via RDMA, and high bandwidth.
Full Explanation
InfiniBand's advantages for HPC and AI are well-established. Low latency (single-digit microseconds) is critical for distributed training synchronization. High reliability means your interconnect doesn't lose or corrupt data. CPU offloads (via RDMA) mean the network adapter handles data transfers autonomously, freeing the CPU for application work. High bandwidth (100–400 Gbps depending on generation) supports large inter-GPU data exchanges. Now, let's address the false options: C says "high latency" is an advantage, which makes no sense — high latency is detrimental. B says "GPU offloads" — that's confusing. InfiniBand enables CPU offloading (CPU doesn't manage transfers), not GPU offloading per se. The question tests your understanding of InfiniBand's value proposition and weeds out misconceptions.
