若使用IB网络，则执行以下命令。 ``` time -p `which mpirun` --allow-run-as-root -x PATH=$PATH -x LD_LIBRARY_PATH=$LD_LIBRARY_PATH -x LD_PRELOAD= /path/to/MATH / lib/libmathlib.so -x OMP_NUM_THREADS=4 -map-by ppr:32:node:pe=4 --bind-to core --hostfile hostfile --mca pml ucx ./wrf.exe ``` - 若使用RoCE网络，则执行以下命令。 ``` time -p mpirun --allow-run-as-root -hostfile hostfile -x PATH -x LD_LIBRARY_PATH -x LD_PRELOAD= /path/to/MATH /lib/libmathlib.so -x OMP_NUM_THREADS=4 -map-by ppr:24:node:pe=4 -bind-to core -display-map -mca pml ucx -mca btl ^vader,tcp,openib,uct -x UCX_TLS=self,sm,rc -x UCX_NET_DEVICES=mlx5_0:1 -x UCX_IB_GID_INDEX=5 ./wrf.exe ``` - --hostfile hostfile：指定使用的节点名字列表。 - -x OMP_NUM_THREADS=4：指定使用的线程数。 - -map-by ppr:32:node:pe=4：指定进程和线程的绑定方式，每个节点32个进程，每个进程4个线程（此处以单节点128核cpu为例）。 - UCX_NET_DEVICES 指定ROCE网络网口。 - UCX_IB_GID_INDEX指定ROCE网络类型。 12. 执行以下命令验证程序正常结束。 ``` less rsl.out.0000 ```
