AMD ATOM Engine - Line hint:

Context Before
AMD has launched a new inference engine called ATOM. Atom can deliver slightly better single node performance, but it is completely lacking on a lot of features that makes it unusable for real workloads. One such example is that it does not support NVMe or CPU KVCache offloading, tool parsing, wide expert parallelism, or disaggregated serving. This has led to zero customers using it in production. Unlike Nvidia’s TRTLLM which generates billions of tokens per hour globally at companies like TogetherAI, etc and does support tool parsing and other features ↗, there are no token factories currently using ATOM due to the lack of the aforementioned features.
Furthermore, maintainers of open-source inference engines like vLLM are disappointed in AMD due to a lack of engineering and GPU resources provided by AMD. For example, Simon Mo, lead vLLM maintainer, states in this GitHub RFC that there is still no working MI355X that he can add to vLLM CI, hence the poor user experience. There are currently zero Mi355X tests on vLLM, while NVIDIA’s B200 has many tests on vLLM. Similarly, there are still not enough MI300X CI machines on vLLM. Upstream vLLM needs at least 20 more MI300 machines, 20 more MI325 machines and 20 more MI355X machines to reach the same level of usability as CUDA.

Context After
Moreover, the vLLM maintainers say that they cannot support day 0 vLLM support for ROCm due to this issue of lack of machine resources. This huge disparity in time to market continues to lead to ROCm lagging behind and leaving a huge opening for Nvidia to continue to charge an insane 75% gross margin (4x markup on cost of goods).
② Atomic Claim
vLLM 將開始取得幾台 MI355X machines，使其 CI test parity 從 0% 提升到至少非零。
