It would be very easy to support 512-bit vectors everywhere, and just emulate them on most systems with a small number of smaller vectors. It's easy for a compiler to generate good…

I've found sorting-network-based filters to be faster than these methods up to size 25x25 or so. It has worse computational complexity, but filters up to that size covers a lot of …

Placing pixel centers at 0.5, 0.5 is only the obvious choice if you think pixels are little squares rather than point samples. Pixels-as-squares makes intuitive sense to people, es…

Halide is generally good for pipelines that do math on multidimensional arrays, so quite possibly. It has a property that I think would make it hard to use for some applications in…

You again? The only other time your account has posted was to plug TVM in a different post on Halide. If you're not a Tianqi Chen sockpuppet, then you should apologize to him for m…

The HDR+ siggraph paper (hdrplusdata.org) states that they use Halide, as does the newer siggraph paper on the Pixel's portrait mode ( http://graphics.stanford.edu/papers/portrait/…

It works but still needs a bit of cleanup. I was planning to get back to it after an upcoming conference deadline. Here's the PR: https://github.com/halide/Halide/pull/3220

Halide doesn't currently have good ways to handle sparse matrices, unless they have some sort of special structure that lets you pack them into rectangular shapes (e.g. a constant …

What Americans call scones are entirely unlike a British scone. A British scone is closest to an American biscuit.

I am indeed Andrew. I'd rather not elaborate - it wasn't a huge amount of code, they added attribution when we complained about it, and they've been very careful to credit us appro…

I find it in poor taste to be plugging TVM on a post about Halide, given TVM's history of lifting code from Halide without attribution (well beyond the "improved" fork of the IR).
