Redefining Scalable AI Performance: OCI Supercomputing in the Cloud (Presented by Oracle)#

GTC 2026 digest Program Core pick San Jose · 16–19 March 2026

Abstract Talk page Slides Recording

Jagwinder Brar, Taylor Newill (Oracle) — Talk, Tuesday, March 17

  • Why: A third-party cloud fabric datapoint at extreme scale — OCI's Acceleron RoCE network connecting hundreds of thousands of GPUs is one of the few large-scale non-InfiniBand production fabrics with public numbers.
  • What: How OCI connects hundreds of thousands of NVIDIA GPUs into AI superclusters claimed at up to 16 zettaFLOPS peak, with Acceleron ultra-low-latency RoCE networking and next-generation GPU instances improving LLM throughput, multimodal/scientific workload speed, and cluster utilization. (from abstract only)
  • How: Abstract does not explain how Acceleron achieves its latency characteristics — that detail is the thing to extract in the room or from the recording.
  • Where applicable: OCI-specific deployment; "Presented by Oracle" means expect positioning, so treat the perf claims as marketing until verified. Still, as a hyperscale RoCE reference point it is worth the skepticism-and-all read.
