Wall-clock time to solution for the same DA problem. EnVar: 65 wall-clock hours (316, 800 CPU hours) on a HPC cluster with Intel Xeon Gold Cascade Lake 6248R CPUs (Data Assimilation). FastDA: 5 wall-clock hours (195, 840 CPU hours) on same HPC cluster (generation of training data), 2 GPU hours on one NVIDIA RTX A4000 GPU (DeepONet training), 1.73 CPU minutes on one Intel Xeon W-1250 CPU (Data Assimilation).
