Our paper titled "SuperBench: Improving Cloud AI Infrastructure Reliability with Proactive Validation" received the Best Paper Award at the 2024 USENIX Annual Technical Conference (USENIX ATC '24).

A line graph comparing the end-to-end performance of Meta’s MoE language model using Azure NDm A100 v4 VMs with and without Tutel. The x-axis is the number of A100 (80GB) GPUs, beginning at 8 and going up to 512, and the y-axis is the throughput (K tokens/s), beginning with 0 and going up to 1,000 in intervals of 100. Tutel always achieves higher throughput than fairseq.
