Benchmark Results

Training Time: Time to solution during training. The number of GPUs ranges from 2 GPUs to 64 GPUs. ImageNet training with ResNet-50 using 2 GPUs takes 20.00 hrs, 36.00 mins, 51.11 secs. With 64 GPUs across 16 compute nodes, we can train ResNet-50 in 1.00 hr, 7.00 mins, 51.31 secs, while maintaining the same level of top1 and top5 accuracy.
