The NIC DMAs packets straight into GPU memory, the kernel JIT-compiles per-packet programs to GPU machine code, and dispatches work using the GPU's SIMT architecture to process many packets in parallel. This shifts per-packet CPU cost onto the GPU, allowing throughput to scale with GPU occupancy rather than CPU core count. Development was done on GCN (Radeon RX Vega) and RDNA2 hardware, leveraging AMD's fully open-source upstream driver stack. NVIDIA and Intel GPU support are not yet viable due to driver maturity limitations. ## Full article daily.dev links to this article rather than hosting it.
