Before revision:  We implement our technique into a Python library called Surfer and find that it makes accurate iteration execution time predictions  on ResNet-50, Inception v3, the Transformer, GNMT, and DCGAN across six different GPU architectures.
After revision:  We implement our technique into a Python library called Surfer and find that it makes accurate iteration execution time predictions (with an average error of 11.8\%) on ResNet-50, Inception v3, the Transformer, GNMT, and DCGAN across six different GPU architectures.
