Could you build this?
No Zero-copy context bridging and KV-cache stitching directly inside the vLLM engine requires specialized expertise in low-level CUDA kernels and distributed LLM memory management.
What it would actually take: Requires custom CUDA/C++ extensions interacting with vLLM PagedAttention block managers, memory-mapped shared memory or NVLink peer-to-peer copies, and modifications to vLLM's internal scheduling engine. Builders need deep understanding of GPU memory paging, attention mechanisms, and low-level C++/CUDA systems engineering.
