Indeed. Notice the last author. Halide has had transparent autodiff for some time now. I am guessing, this is follow-on work in the usual academic style. (Not trivializing at all.) I've been watching Halide for a while as I really like it, intuitively. Also it wasn't that hard to bring up on FreeBSD with a few patches, where it performs more or less exactly as on Linux when configured cpu only. That's solid generic programming, to say the least. However... I have no recent decades experience with HPC but I would be surprised if dense tensor operations were a significant component of current workloads. Could be though!
