This dataset hosts NVIDIA Nsight Systems profiles of fastvideo running Wan-AI/Wan2.1-T2V-1.3B-Diffusers text-to-video inference on a 4× L40S node (PCIe Gen4 x16, no NVLink), plus the static plots and measurement summary used to discuss the trace.
The trace shows a bandwidth-bound, same-stream-serialized workload: compute kernels and NCCL SendRecv collectives share a single CUDA stream, so there is no compute/comm… See the full description on the dataset page:
