      @marcan42 and the variable trip count loops makes me as a compiler person REALLY wish those could be constants...

      @FioraAeterna Thankfully none of that is performance-sensitive code, the OpenCL kernel is all that matters :-)

      @FioraAeterna This is the horrible thing it's trying to compute (well, the worst step). 128 ins, 128 outs, full mesh.pic.twitter.com/aOpHDYoL0z

      @FioraAeterna The "kernels" are distinct 3x3 convolutions. So there are 128x128 independent 3x3 kernels, for each in,out pair.

          @marcan42 does this mean there's 128^2 coefficients?

          @FioraAeterna 3² × 128² coefficients, yes.
