Hi Kaiming, This most likely means that for some reason, the GNI provider is not getting a valid RDMA cookie/ptag.
How are you trying to launch your job? (aprun, srun, MPICH hydra launcher). Also, to help me try to reproduce the error, could you post your MPICH configure options (I'm assuming your are building MPICH yourself). Thanks, Howard Am Do., 20.
