He's describing the Cuda execition model. More interestingly, it's the same model as Intel's Implicit SPMD Program compiler (ispc, God that name is awful). But

More interestingly, it's the same model as Intel's Implicit SPMD Program compiler (ispc, God that name is awful). But ispc works across SIMD lanes.
- petermcneeley 1y agoYes this is just the GPU programming model without the hw perks (subgroups etc). Im impressed if he came up with it on his own but its pretty clear from the article that he didnt. The GPU model works because the GPU is just wide SIMD with automagical scheduling. To apply this to the CPU might be misguided unless you use SIMD aka like ISPC.
