TensorRT's operator fusion merges multiple consecutive small operators in a computation graph into a single large operator, reducing the number of GPU kernel launches and memory reads/writes of intermediate results; a typical fusion operation can combine convolution, batch normalization, and activation function into a single GPU kernel call.
