Nvidia's Ujval Kapasi to Discuss Agentic PyTorch Performance on Vera Rubin
Agentic pipelines shift the performance bottleneck from single-model inference to the full chain of tool calls, data movement and distributed execution, so framework-level tuning matters more than raw GPU throughput. Engineers building agents on PyTorch, Triton or vLLM can use the co-design lessons to plan their stack for Vera Rubin-class hardware. The keynote is a marker for where Nvidia's agent infrastructure work is heading.
Nvidia's Ujval Kapasi will present "PyTorch Performance for Agents on Vera Rubin" at PyTorchCon 2026. The keynote examines what agentic workloads, which chain reasoning, tool calls, code execution and distributed inference in a single request, demand from the PyTorch stack. Using Vera Rubin as a case study, he covers hardware and software co-design across CPUs, GPUs, memory and networking. The talk also details optimizations across PyTorch, Triton and vLLM on Vera Rubin.
