DeepSeek open-sources Ascend infrastructure components in collaboration with Huawei Ascend
The Ascend counterpart to DeepSeek's GPU infrastructure stack has been open-sourced, including the TileLang high-level compiler, DeepGEMM, FlashMLA, TileKernel and DeepSelect kernel libraries, and the DeepEP distributed communication library. Huawei contributed the jointly defined SuperPoD Flex and UBL128 fabric with 128-card 3.2 Tbps single-layer scale-up and 256,000-card two-layer scale-out. Reported DeepEP throughput is 375 GB/s for dispatch and 347 GB/s for combine; on Ascend 950, DeepSeek-V4.1-Flash offline inference runs at 2,469 tokens/s per card at TPOT=5ms.
