Optimizing LLM Inference with Hybrid Parallelism
antirez · x · 2026-07-10
While discussing DwarfStar's target deployment, the author noted that 8 L40S GPUs aren't the ideal setup, but tests were conducted since a friend had the machine available.
Because vLLM doesn't support Ada architecture NVIDIA cards with DeepSeek v4 Flash, the author had Fable adopt a compromise between pipeline and tensor parallelism to balance prefill and generation speeds. The post emphasizes that in the current landscape, temporarily forking and modifying code to accommodate different hardware has become essential.
