Failed run multiple nodes scripts on NVIDIA A100 #4

Hello! I found that when I use openmpi, ucx, cuda, and gdrcopy to compile OpenCFD-SCU-v3.0, I can only run it on a single node. Running on multiple nodes will result in a segmentation fault. Has this program been tested on NVIDIA GPUs before? 企业微信截图_1711640613617

More investigation on Nvidia GPUs is needed.
