Thank you for sharing! RE: ~15:30 Modular vs. Fixed Switches - Are deep buffers desirable in RDMA? Jitter and latency variation and associated frame reordering over parallel flows seems like a sensitivity. Don't these absurdly integrated systems (GPU to GPU) have their own transmission control mechanisms and realtime knowledge of the state of the flows? Is the Ethernet network doing ECN or Pause in these deployments? I think the slide at 21:50 addresses my questions. Sorry. Impatient.
