Chinese chipmaker Moore Threads has launched its first domestically-produced 1000-card AI training cluster, dubbed the KUAE Intelligent Computing Center. A central part of the KUAE cluster is Moore Threads new MTT S4000 accelerator card with 48 GB VRAM utilizing the company's third-generation MUSA GPU architecture and 768 GB/s memory bandwidth. In FP32, the card can output 25 TeraFLOPS; in TF32, it can achieve 50 TeraFLOPS; and in FP16/BF16, up to 200 TeraFLOPS. Also supported is INT8 at 200 TOPS. The MTT S4000 focuses on both training and inference, leveraging Moore Thread's high-speed MTLink 1.0 intra-system interconnect to scale cards for distributed model parallel training of datasets with hundreds of billions of parameters. The card also provides graphics, video encoding/decoding, and 8K display capabilities for graphics workloads. Moore Thread's KUAE cluster combines the S4000 GPU hardware with RDMA networking, distributed storage, and integrated cluster management software. The KUAE Platform oversees multi-datacenter resource allocation and monitoring. KUAE ModelStudio hosts training frameworks and model repositories to streamline development.

With integrated solutions now proven at thousands of GPUs, Moore Thread is positioned to power ubiquitous intelligent applications - from scientific computing to the metaverse. The KUAE cluster reportedly achieves near-linear 91% scaling. Taking 200 billion training data as an example, Zhiyuan Research Institute's 70 billion parameter Aquila2 can complete training in 33 days; a model with 130 billion parameters can complete training in 56 days on the KUAE cluster. In addition, the Moore Threads KUAE killocard cluster supports long-term continuous and stable operation, supports breakpoint resume training, and has an asynchronous checkpoint that is less than 2 minutes. For software, Moore Threads also boasts full compatibility with NVIDIA's CUDA framework, where its MUSIFY tool translates CUDA code to MUSA GPU architecture at supposedly zero cost of migration, i.e., no performance penalty.
