The post covers why Random Forests are used for ambiguous genomic position classification, how the tree data structure was flattened into a GPU-friendly BFS array layout with a 16-byte node struct, and how two WGSL compute shaders (traverse and reduce) handle inference. It also details multithreading with Rayon, pipelined GPU submission across three models, f32 precision verification, and a zero-copy unified memory optimization for Apple Silicon via wgpu's MAPPABLE_PRIMARY_BUFFERS feature. ## Full article daily.dev links to this article rather than hosting it.
