    C500 vllm-0.23.0是否支持Qwen3.6-35B-A3B? 已解决 2026年8月19日 10:38

    8专家并行,docker是vllm-metax-0.23.0-maca.ai3.8.0.103-torch2.10-py312-ubuntu22.04-amd64.tar.xz,先是带CUDA graph的启动失败,报驱动层面的trace,index_elementwise_kernel越界;换eager启动以后,发一个请求出现:

CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect. For debugging consider passing CUDA_LAUNCH_BLOCKING=1 Compile withTORCH_USE_CUDA_DSA` to enable device-side assertions.

    C500 GPUDirect RDMA:GPU 写显存对网卡 P2P READ 不可见(发送方向) 已解决 2026年7月28日 16:58

    问题:C500 显存经ibv_reg_dmabuf_mr注册给mlx5网卡。GPU kernel写这块显存后,GPU的写停在L2域,网卡通过dma-buf P2P读HBM读到的是旧值。
    提问:
    1. C500 GPUDirect 是否支持网卡从显存 READ(从显存发送),还是只支持网卡写显存(接收)?
    2. 若支持,有没有让GPU kernel的显存写对网卡P2P读可见的 API(L2→HBM flush/system-scope store/dma-buf 注册前的正确内存属性)?mcDeviceFlushGPUDirectRDMAWrites是接收侧,有无发送侧对应?

    C500是否支持GPU-initiated 通信 已解决 2026年7月15日 09:39

    目前想把C500的RDMA传输控制面从CPU改为由GPU kernel来做,需要GPU和MACA支持GDAKI / GPUDirect Async,请问目前是否支持,有相关文档吗?
