Experimenting a bit with the /d2cgsummary and /d1reportTime flags described by Aras here and here I noticed that one of our functions was consistently showing up in the Anomalistic Compile Times section:
1> Anomalistic Compile Times: 2
1> create_truth_types: 0.643 sec, 2565 instrs
1> draw_nodes: 0.180 sec, 5348 instrs
Minimal D3D11 reference implementation: An uncluttered Direct3D 11 setup + basic rendering primer and API familiarizer. Complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion that should be easy to follow from the code alone. ~200 LOC. No modern C++, OOP or (other) obscuring cruft. View on YouTube
Also check out Minimal D3D11 pt2, reconfigured for instanced rendering and with a smaller, tighter, simplified overall code structure, or Minimal D3D11 pt3, with shadowmapping + showcasing a range of alternative setup and rendering techniques.
| In shader programming, you often run into a problem where you want to iterate an array in memory over all pixels in a compute shader | |
| group (tile). Tiled deferred lighting is the most common case. 8x8 tile loops over a light list culled for that tile. | |
| Simplified HLSL code looks like this: | |
| Buffer<float4> lightDatas; | |
| Texture2D<uint2> lightStartCounts; | |
| RWTexture2D<float4> output; | |

I recently happened upon a very interesting implementation of popen() (different API, same idea) called popen-noshell using clone(2), and so I opened an issue requesting use of vfork(2) or posix_spawn() for portability. It turns out that on Linux there's an important advantage to using clone(2). I think I should capture the things I wrote there in a better place. A gist, a blog, whatever.
This is not a paper. I assume reader familiarity with
fork()in particular and Unix in general, though, of course, I link to relevant wiki pages, so if the unfamiliar reader is willing to go down the rabbit hole, they should be able to come ou
